Bloom Box 60 Minutes Segment

Bloom Energy, a California startup with big financial backing, is about to launch (tomorrow) their Bloom Box, a fuel cell device that they hope to see in the home of every American in the next 5 to 10 years. Holding up two tiny boxes, K.R. Sridhar of Bloom Energy told Lesley Stahl in a recent 60 Minutes interview that they were enough to power a single American home (incidentally, the same number of boxes could power 4 Asian homes, and UK homes require just one).

Many, however, are skeptical that these Bloom Boxes will be able to deliver on their power-saving promises. Michael Kanellos, editors of Greentech Media, has doubts. His concerns are twofold. First, big firms such as GE already have patents for fuel cells but have not yet begun to sell them, primarily because they cost too much to be competitive. Second, well-funded projects like this one with a protracted product development stage—Bloom Energy has been working on its fuel cells for about 10 years and has already received more than $400 million in funding—tend to fall flat when they finally “go live.”

But Bloom Energy already has several clients that have been using the Bloom Box for 9+ months with a lot of success. The installation on the eBay lawn has been running for about that much time and apparently has already saved the company more than $100,000 in electricity costs, providing about 15% of the building’s energy. Their system produces about five times more energy than their acres of solar panels, too!

What remains to be seen is whether the Bloom Box will be affordable for the average consumer looking to save energy at home. Sridhar promises that it will be affordable for Americans, and even for communities in developing countries. We’ll find out tomorrow!

InCharge Battery Station

The Greener Gadgets Design Competition is on in anticipation of Greener Gadgets Conference to be held in New York City on February 25. You can make your voice heard by voting for the gadget you find more eco-friendly.

Consider, for instance, the BuLogics Smart Grid Home Controller. It’s billed as the world’s first smart grid-compatible wireless controller. By installing the Z-Wave HAN in your home, you can automatically shut down appliances and electronics that are not being used during peak electricity demand times. This occurs when your local utility grid sends a demand change request and allows you to reduce your monthly power costs. You can also monitor how much you’re using and saving using a wireless computer or cell phone. It’s a great way to really get a handle on when and how much energy you use in order to save power as much as possible.

Another option is the InCharge Battery Station by Pensa. We all know that using rechargeable batteries is not only cost-effective, it’s more environmentally-friendly than disposable batteries. But it can be a pain to plug in the charger and hook up the batteries. With the InCharge Battery Station, simply drop the batteries into the base—it automatically sorts them and begins charging. The LED light indicates the relative charge in each individual battery, holding charged batteries until you need them so that you always have batteries at the ready.

And if you want to produce your own power to charge your electronic devices, check out the RollerGen. As you cycle, the RollerGen will automatically charge two devices—cell phone, mp3 player, and so on—simultaneously. In fact, a 2-mile ride can charge a smartphone!

Or how about the Turbine Light? It’s a renewable energy harvesting device that doubles as a renewable energy system. As the wind turns the turbine, energy is created, which can be used to power the lighting at night. The wind is generated by weather or by passing vehicles.

So don’t miss out on your opportunity to vote for the greenest gadget (deadline February 25)!

Sanyo Eneloop electric bike YouTube video from CES 2010

For the summertime commute or for year-round transportation for those living in balmy climes, the Eneloop Bike by Sanyo could just be one of the biggest money and energy-saving devices you could ever buy. Forget about trading in your SUV for a hybrid vehicle! If you’re interested in truly low-cost driving, then check out this electric bike.

The Sanyo Eneloop electric bicycle is a very low-energy, cost effective means of getting from point A to point B, with little in the way of greenhouse gas emissions along the way. With a rack on the back, you can carry your work bag, groceries, or your child as you run errands, head to the office, or make a trip to a friend’s house. Plus you have the advantage of getting fresh air in the meantime!

When you pedal, it goes—the faster you pedal, the faster you move, up to 15 miles per hour. And by adjusting the built-in Power-Up mode, the bike automatically gives you assistance from the motor while you pedal so that you can ride comfortably uphill with very little energy (they state that it will increase your riding distance by 1.8 times).

Using “Loop charging” the bike circulates energy, charging the battery while you ride. When you apply the brakes, the rear brake acts like a generator that charges the battery. It can also be plugged in to charge it in 3 hours and 30 minutes.

It is available at a variety of retailers for about $2,300, including Best Buy (limited distribution) in their Personal Transportation department.  It’s only available in the white color and one size, but they believe the frame fits about 80% of the people in the market. The seat is adjustable up and down. You can also customize the graphics package for the bicycle (much like your iPhone), so you can personalize your vehicle for an extra charge.

Concord Keystone solar-powered handbag helps you save power on the go

Concord Keystone Trading LLC, an interesting little company, has recently produced a new solar-powered tote bag that’s stylish as much as it is an energy-saver. Unlike many other solar-powered backpacks, briefcases, and handbags that are so not trendy or chic in the least, the 4U2ReUSE (for you to reuse) Solar Sling actually has some good style sense.

But more than that, the bag provides renewable energy while exposed to solar energy during the daytime. Using G24i’s solar panel technology, which is a thin-film variety form of photovoltaics that is capable of charging even when the sun hides behind the clouds, the on-board battery stores the energy from the panels and then can dole it out to small electronics via USB connector. It can charge anything from a cell phone or smart phone to digital cameras and iPods. When in full sun, the system should be fully charged within approximately five hours, according to Concord.

To add to the bag’s eco-credibility, it is made from recycled PET plastic bottles and of course can be used in place of disposable plastic bags handed out at a variety of vendors—from your local grocer to fashion retail outlet.

The bag’s other features include a compartment for a laptop, a key clip, and spacious pockets. It will be available in four color combinations and comes with the battery pack.

Concord Keystone featured this new product at CES, the consumer electronics tradeshow that took place in Las Vegas, Nevada. It has yet to be priced, though is expected to come on the market soon.

DIY solar is now a reality with solar systems available at Lowe's via Flickr - OregonDOT

Starting now, you can purchase easy-to-install solar photovoltaics from Lowe’s, carrying them home and installing them yourself, if you so desire. This first-ever, off-the-shelf option was recently announced by Akeena Solar Inc and is a way for DIY consumers to get the renewable energy system they want.

Akeena Solar is a manufacturer and installer of solar power systems and has hooked up with 21 Lowe’s home improvement stores in California to offer these plug-and-play solar panels to the general public.  Packages include racking, wiring, grounding, and all of the other parts needed to produce your own energy. Plus they have built-in inverters so they output AC power, which means no high-voltage wiring is required. These simple systems are supposedly to be installed easily by experienced do-it-yourselfers as well as electricians and HVAC contractors.

Barry Cinnamon, CEO of Akeena Solar, had this to say:

“The PC revolution in the computer industry occurred when new technology made PCs easy to use and affordable. Likewise, with panels becoming plug-and-play appliances, the solar revolution has started. The availability of solar panels in Lowe’s stores makes it easy for homeowners to go solar and is a big step toward getting solar on every sunny rooftop.”

The award-winning solar panels will be in Lowe’s Energy Centers where customers, using an interactive information kiosk, create their own unique energy plan according to their budget and energy goals. Additional energy-saving products will also be available in the Energy Centers.

The good news is that Lowe’s Energy Centers will be added to more stores throughout the US and Canada during 2010.

Obama administration recently announced a new clean energy REDI program

The Obama administration announced a new program on December 14: The Renewables and Efficiency Deployment Initiative (REDI), which will offer $350 million in funds to accelerate the development of clean energy technologies. As both a domestic and global initiative, some of the funds ($85 million) will go into a joint coffer (supported by other countries such as Australia, Norway, Switzerland, Netherlands, the UK, and France) to be used to develop and deploy clean energy tech around the world.

The program will operate in several industries, including advanced vehicles, bioenergy, building and industrial efficiencies, smart grid technologies, carbon capture, high-efficiency coal,  and of course, solar, wind, and marine energy. The official REDI website outlines the following programs that will receive this funding:

• The Solar and LED Energy Access Program will accelerate deployment of affordable solar home systems and LED lanterns to those without access to electricity.  This program will yield immediate economic and public health benefits by providing households with low-cost and quality-assured solar alternatives to expensive and polluting kerosene.
• The Super-efficient Equipment and Appliance Deployment Program will harness the market and convening power of MEF countries to improve efficiency for appliances traded throughout the world.  A number of MEF countries have implemented, or are exploring, incentive programs for energy-efficient appliances. Coordinating incentives, standards and labeling systems can create unprecedented economies of scale for these appliances.

• The Clean Energy Information Platform will establish an online platform for MEF countries to exchange technical resources, policy experience and the infrastructure to coordinate various activities in deploying clean energy technologies, and share this information with the world.

• The Scaling-up Renewable Energy Program (S-REP), under the World Bank’s Strategic Climate Fund, will provide policy support and technical assistance to low-income countries developing national renewable energy strategies and underwrite additional capital costs associated with renewable energy investments.  Funding through Climate REDI will accelerate the launch of S-REP.

Further, it states that REDI will use the following tools to disseminate the new technologies:

1. Quality assurance to guard developing country consumers against sub-standard renewable energy products;
2. Minimum efficiency standards to remove the lowest efficiency appliances from the market;
3. Labeling to guide consumers to quality-assured and high-efficiency products;
4. Financing for scale up of early-stage low-carbon products, to bring down costs and remove barriers to deployment and to catalyze investment by the private sector;
5. Information sharing that enables all energy stakeholders to access state-of-the art information on technology and best practices.

Solarmer Energy's organic photovoltaic technology

There have been some interesting developments in the world of solar this month and two in particular seemed share-worthy. First, ShadePlex, purportedly the leader in solar-electric flexible-use architectural fabrics, is now offering color-coordinated solar products! Their energy-producing fabric frames come in a variety of colors (red, yellow, green, or bright blue) so that you can match them to various surfaces.

While the fabrics themselves don’t product energy, the thin-film, flexible solar material is bonded to architectural fabrics to form a flexible, framed solar panel. They can be used to cover walkways and canopies, as tents, and in other flexible structures. And because of their lightweight materials, they require little to no reinforcement. Interesting concept!

Second, Solarmer Energy Inc has recently boosted the efficiency of their flexible plastic solar panels (organic photovoltaic technology or OPV) from the 7.6% efficiency they achieved earlier this year to 7.9%, a number that has been confirmed by the US Department of Energy. Though that may not seem like a huge bump in efficiency, it is still movement. And since Solarmer aims to reach 10% efficiency by the end of 2010, every bit counts. Here’s what they said regarding the breakthrough:

“First, low-cost plastic is used as the active materials to convert solar energy into electricity. Thanks to the extraordinary light absorption capability of the plastics, the active plastics layer is extremely thin – only a few tenth of micrometer thick, i.e. less than 1/1000 of silicon cell. This material cost is significantly lower.

Second, very low cost printing techniques can and will be used to manufacture plastic solar cells (just thinking of the newspaper). The combination gives much lower cost of equivalent energy (only ~10 – 20% that of silicon technology). In addition, the fabrication process is both low temperature and environmentally friendly, significantly reduces the amount of energy consumption in the manufacturing process.”

COP15 America.gov Daily Video - check it out!

The day has finally arrived: today is the first day of the Copenhagen climate change talks begin. The COP15 (15^th Conference of the Parties as it is known) hopes to put together a global agreement that would work to reduce greenhouse gas emissions to within safe levels – an agreement that would take over from the Kyoto Protocol which expires in 2012. It’s an audacious goal, but a worthy one. It’s a task we should not shrink from.

But there’s a lot to accomplish before truly binding agreements can be put in place. Perhaps the most contentious issue is that of how to regulate emissions in rich versus poor countries, with the poor nations demanding aid before they commit to targets, and rich nations requiring climate commitments before they send aid.

And there is also widespread disagreement as to the appropriate size of carbon reductions. While Obama has committed that the US will reduce its emissions by 17% below 2005 in the next few years, most scientists and global leaders contend that this is far too little.

Yet there is growing momentum behind the movement. Countries that could perhaps have the biggest impact on climate change in the near future – India, China, and Brazil being chief among them – have made public commitments to support the climate talks (here’s hoping they don’t walk out part-way through the proceedings as some have threatened to do). So there is hope.

Want to get involved? If you haven’t already, please do! Here are some resources for educating yourself and then digging in to make a difference during these important talks:

• Find up-to-the-minute information on the talks through the common editorial being put together by 56 newspapers in 45 countries.

• For a really quick primer, check out COP15: What’s at Stake in Under 5 Minutes.

• Then get active by signing petitions and encouraging others to do the same. Get involved by speaking up on Facebook or Twitter, sign up with the Tck Tck Tck and 350.org campaign or Hopenhagen, or get involved in civil protests (find one near you through Beyond Talk). You CAN make a difference.

Solar Cookers International

If you’re looking for a meaningful way for you to symbolically save power this holiday season, why not consider sponsoring a solar cooker through Solar Cookers International? In fact, sponsoring a solar cooker through this organization could make a very good gift. Making donations to nonprofit organizations in someone else’s name rather than purchasing something they neither need or want is a great way to support a good cause, reduce your consumption and waste, and help perpetuate a more sustainable future.

Of course, there are many great options for nonprofit gift giving but this is certainly a great one. Solar cookers come with many benefits for fighting climate change. Not only do they require no dirty energy, their use helps to protect forests and human health.

Traditionally, people in developing countries cook over open fires by burning things like wood and animal manure. The resulting air pollution leads to millions of respiratory problems and many deaths. It is estimated that as many as 2 million children die from health problems caused by the black carbon smoke emitted by cooking fires. And this black carbon is said to be the second more significant global warming pollutant in the world! Solar cookers create none of this air pollution and are therefore healthier for people to use. Of course, when forests are protected, they are able to help sequester carbon, too.

And instead of spending time to forage for firewood with the potential for depleting local forests, women who cook with solar cookers can do so without harming their community’s natural resources and have more time for other endeavors, such as entrepreneurial work or caring for their children.

The Solar Cooker International’s kit comes with the solar cooker and a pot along with tips and hints on how to use them. What’s even better is that a water indicator is included. This makes it possible for women to measure whether harmful microbes have been killed in the water so that they know whether it’s safe to drink.

So make a difference this holiday season—donate a $50 solar cooker to someone in a developing nation to change a life and offset emissions in the process. Of course, you could also purchase one for yourself or a family member or friend to get into the renewable-cooking movement yourself!

Good news via a study out of Yale, Berkley, and the University of Illinois. The study, entitled Clean Energy and Climate Policy for U.S. Growth and Job Creation outlines some very positive statistics on where we’ll be after the implementation of a climate bill in the US. According to the analysis by these folks, a climate bill will have exceptionally-positive benefits for both job creation and the economy: it could potentially boost the bottom line by $111 billion by 2020 as well as add 2 million jobs at the same time.

These numbers depend on a few key factors being present in any bill passed in the US. For instance, it requires that targets for emissions reductions be at least 17% nationwide by 2020, and then 83% by 2050. Additionally, utilities will need to get their electricity from renewables at a rate of 20% or greater.

According to the report’s summary, the key findings are as follows:

“All 50 states can gain economically from strong federal energy and climate policy, despite the diversity of their economies and energy mixes.

“Contrary to what is commonly assumed, comprehensive national climate policy does not benefit the coasts at the expense of the heartland states.

“The country as a whole can gain 918,000 to 1.9 million jobs, and household income can grow by $488 to $1,176, by 2020 under comprehensive energy and climate policy.”

The report even offers a state-by-state analysis of what effects a climate bill will have on local economies. This is all very good news for a skeptical and fearful society convinced that dealing with climate change will cost too much.

The ReVerb comes with nifty feedback icons

If you’re looking for the perfect gift for the techie in your life, look no further. Regen, a company that specializes in making solar-powered gadgets, most notably of which is their ReNu which powers any of their other devices such as the iPod Dock, Audio Dock, and Side Light.

But the most recent addition to the Regen family of solar gadgets is the ReVerb, a high-quality speaker with an integrated photovoltaic solar panel that generates enough energy to power the speaker for up to 12 hours at normal volume (to get it fully charged takes about 20 hours). Simply plug in your iPod Touch or iPhone to access digitally-stored media files and away you go.  It also comes equipped with 2x USB ports, 1x USB input for charging the unit, as well as a nice little LCD display (about four inches).

Though the speaker can also be powered by a regular AC adapter, it is meant to be run with solar power. And it provides some very nice quality sound, according to reviews. The Earthtechling reports that:

“It generates sound equal to that of a regular 60-watt speaker and sports stereo drivers and a sub-woofer.”

You can also use the speaker to control your audio device, whether you want to play/pause, increase/decrease volume, or select a different track. And one of the best parts is that it actually gives you feedback about how you’re using it. For instance, if you’re running low on power because of a lengthy playback session, it’ll let you know that it’s dissatisfied by displaying an unhappy face. Now that’s a full-service speaker!

But it doesn’t come cheap: about $2,300 each! And they won’t be available until April 2010.

Georgia Tech - close-up of 3-D solar cells

It just makes sense that solar cells be exposed to as much sunlight as possible, right? Not with Dr. Zhong Lin Wang’s new nanostructure optical fiber “hidden” photovoltaic cells. This Georgia Institute of Technology professor, along with a team of researchers, recently developed a new way to create renewable energy, and it could spell a major change in the roof-top solar panel dominated industry—and in fact may take solar collectors underground. According to Wang:

“Optical fiber could conduct sunlight into a building’s walls where the nanostructures would convert it to electricity. This is truly a three dimensional solar cell.”

These solar collectors are made by modifying common optical fibers used in the telecommunications industry for data transport, applying zinc oxide (think lifeguard nose protection) as a conductive coating, and then adding nanowires as well. Then a dye-sensitized material is added that uses a photochemical system to produce energy. These are cheap to make, are highly durable and flexible, and very versatile. In fact, they could be installed into walls, roofs, and other building materials without any visual disturbance, making the collection of energy possible on nearly any surface.

“This will really provide some new options for photovoltaic systems,” Wang said. “We could eliminate the aesthetic issues of PV arrays on building. We can also envision PV systems for providing energy to parked vehicles, and for charging mobile military equipment where traditional arrays aren’t practical or you wouldn’t want to use them.”

One drawback is efficiency. Unlike traditional silicon-based solar cells which get about 12% efficiency, these currently only about 3.3%, but with diverse applications in which this technology could be used, the trade-off may just be worth it. And they hope to increase efficiencies to about 8% in the near future.

All eyes were on the Chinese-US talks the last week as Obama met with key leaders in the Asian country. With clean energy being one of the biggest issues on the table for the first time in a really public manner, we were all holding our collective breath to see whether anything would get done. And it seems that there is reason to hope!

The US and China, knowing the joint sway they will hold over the Copenhagen talks in January, were eager (or so it appeared) to see how they could influence the talks for good by developing a renewable energy agreement. These the two biggest emitters were able to agree on a broad plan that would help to bring about serious advances in clean energy.

The seven-point plan included the following:

• They US and China will establish a Clean Energy Research Center to facilitate joint research and development of renewable energy technologies. The center will receive both public and private funding to the tune of $150 million over the next five years.
• A joint US-Chinese Electric Vehicles Initiative was announced that will see joint vehicle standards, public education, demonstration projects, and more.
• Together, China and the US will work on an Energy Efficiency Action Plan for buildings, consumer products like appliances, as well as industrial facilities.
• A new US-China Renewable Energy Partnership was launched that will help to support renewable energy deployment and regional partnerships for sharing expertise and best practices.
• “Clean” coal was part of the overall strategy—21^st Century Coal. The two Presidents will work together to develop large-scale carbon capture and storage projects for coal-fired plants.
• Working together, the two countries will explore Shale Gas Resources within China using the experience gained on US soil.
• A new Energy Cooperation Program between China and the US will also be established to leverage private sector resources that will support smart grids, green buildings, combined heat/power, renewable energy, clean coal, and more.

Americans waste an enormous amount of energy powering devices as they sit idle. Whether it’s the television or DVD player, cell phone chargers, appliances, or toys, this “phantom drain” on your energy bill could be adding significantly to your monthly electricity costs. In fact, according to the Union of Concerned Scientists, vampire energy can account for as much as 5 to 10 percent of the average home’s electricity bill! Check out this fun graphic that illustrates where energy is most commonly wasted.

While unplugging unused electronics and appliances is perhaps the most simplistic way to avoid this kind of energy waste, it’s not the only method by far. Power strips are a more automated, convenient method of reducing your energy consumption, and they make great holiday gifts, too! Here are three great options for you to consider as you prepare to start shopping for those on your gift list:

Turn off unneeded energy-drains with the Belkin Conserve’s wall switch for the power strip. With eight always-on outlets and six that are controlled with the wall switch, you can customize which electronics and appliances get switched on and off with a flick of your finger.

The Isolé® IDP-3050 Plug Load Control has a unique, ultra-convenient feature: a motion detector that will switch electronics on when it senses someone in the room. And of course, it shuts them down when movement stops, too. Price: $90.

With a claim that it can pay for itself in as few as six weeks, the SmartStrip is a veteran in the intelligent power strip world. It can “sense” the flow of electrical current, turning off peripherals when they’re not in use. It also protects against power surges.

Marriott is expanding its green hotel program

‘Tis the season to travel as people get ready to hit the road for Thanksgiving celebrations, book ski trips, plan beach getaways to escape the winter, and prepare to get together with family and friends for Christmas, Hannukah, Kwanzaa, or holiday festivities. We love to travel, but hopping on a plane or driving long distances can have a negative impact on our carbon footprint.l

So it’s nice to see hotel chains take climate change and environmental protection seriously. Marriott has recently been running a “green hotel” trial project, testing out the viability of greening their accommodations. The program involved initiatives to reduce water and energy consumption, cut waste, and lower toxicity and improve indoor air quality by choosing greener products used in the facilities.

There were 30 hotels in the initial trial, but Marriott just announced that it will be expanding its eco-friendly hotels by 1,000 percent to cover 500 hotels! But the move isn’t completely altruistic. In this depressed economy, the massive hotel company is also motivated by the bottom line. It seems that they achieved some sizable financial savings through their green hotel program , both in constructing and running the greener facilities.

That’s good news for the hotel industry as a whole, and hopefully Marriott’s ambitious plans will be a signal to their competitors that being green is better for business. So, as you plan your holiday travel, keep green in mind. Choose hotels with a green stamp of approval, ask about your preferred chain’s green policies, and leave comments when you check out encouraging conservation.

Barnes & Nobel Nook E-Reader

The world of e-book readers is in constant change these days, it would seem. This past month, two new e-readers were released to give Amazon’s Kindle a run for its money in the eco-friendly book space.

First up is Barnes and Noble’s new Nook, an e-reader with a 10-day battery life and weighing in at only 11.2 ounces. It comes with WiFi and AT&T 3G, a replaceable battery, PDF support, and has two screens—one for reading and the other (color) for easy browsing. It’s available now for about $260 (about the same as the Kindle) and can store 1,500+ eBooks, magazine, newspapers, and more. A fantastic green feature: you can “lend” your books to friends for up to 14 days!

Rumor has it that Apple will also soon be releasing their version of the e-reader with the Tablet (set to come out in 2010 according to BusinessWeek).

Using an e-reader saves energy in a number of ways:

• By reducing the number of books that are produced, we reduce deforestation, which in turn conserves carbon-absorbing trees.
• You’ll need less shelf space to store your books, which means you can presumably have a smaller home (less square footage to heat and cool).
• Buying books electronically saves on the fuel you’d use to go to the bookstore or the shipping require should you order a paper book online.

In fact, a report by the Cleantech Group has concluded that e-readers like the Kindle 2 can help you go green by saving 1,074 kg of CO2 annually (assuming you would avoid buying about 3 physical books/month).

Using the parabolic structure of the concentrating solar system, this new MicroCSP can be used to provide a building with a variety of services, including air conditioning, drying, dehumidification, desalination, steam, and hot water.  It’s both lightweight and more rugged (so they say) than traditional solar PV systems, making it simple and easy to mount and fasten to almost any rooftop. It is then integrated into existing natural gas systems.

Sopogy has a proprietary integrated tracker technology to boost its efficiency and has priced the new system 30% cheaper than other rooftop solar technologies (such as solar photovoltaics, according to the company). They also tout a 3-year payback on the system when energy savings are taken into consideration.

“Sopogy has incorporated our unique frame, ready-to-assemble manufacturing and automated controls into a new compact product designed for rooftop installation. This brings concentrating solar power to the commercial and industrial facility in a cost effective, space efficient and contractor friendly solution. All combined our customers receive the fastest paybacks available in solar helping them save money and fight global warming” – Darren T. Kimura, President and CEO, Sopogy, Inc.

Thermostat at 69 degrees Via Flickr - t-bet

It’s the beginning of November, and for many that means winter has arrived, and with it heating season. Keeping indoor temps at a comfortable level costs North Americans a great deal in terms of money and energy. In fact, the average American will spend nearly $2,000 every year for heating, whether that be with oil, gas, electricity, or wood stove. It all adds to our climate footprint as well, with heating being one of the biggest residential contributors to greenhouse gas emissions.

But there are some very cost-effective (free!) things you can do to lower your heating bill and cut your carbon dioxide emissions. With just a few quick little environmentally-friendly seasonal changes to your heating system, you could help the country reduce its dependency on fossil fuels while saving energy, too.

Programmable Thermostat at 60 Degrees Via Flickr - Mr.Thomas

Lower your thermostat

Your thermostat is one of the most important tools you could use to lower your home’s energy impact. Learning how to maximize thermostat settings for efficiency is a great way to cut how much energy you use to heat your home.

Each season, you should readjust your thermostat settings. Now that it’s winter for many of us, it’s time to turn the setting down to 68°F or lower for those times when your home is occupied. It can go even lower when you’re asleep and when you’re not at home to further reduce your heating costs.

Make your job even easier by installing a programmable thermostat to do the work of adjusting for you. There are rebates for this simple upgrade for many states, and a programmable thermostat may just save you $150 every year on heating and cooling costs. Get more ideas from the Alliance to Save Energy.

Reverse Ceiling Fan in Winter Via Flickr - dane brian

Reverse your fan direction

Yes, it might seem counterproductive to run a fan in the middle of the winter, but a ceiling fan can actually help to reduce your heating costs. How? Well, if you reverse your fan’s rotation from counter-clockwise to clockwise, you’ll help to force warm air that’s trapped near the ceiling down to floor-level. This will ensure that your heated air is circulated more evenly, reducing the work your heating system has to do to keep you warm. It’s a low-free way to lower heating bills. Find out more at the Look Up Campaign.

Layer up

Yet another no-cost way to save on heating bills is the layering technique. What do we mean? Well, during the day, you can warm yourself up inexpensively by layering your clothing. As you get warmer, remove a layer or two. Likewise at night while you sleep—pile up the quilts to stay cozy at without raising the cost of heating. ENERGY STAR has even more ideas for how to heat and cool efficiently.

Met Office Climate Change Map

A new climate change map of the world, launched by the British government this past week at the Science Museum in London, shows the widespread impacts of a 4°C rise in temperature, and the picture is not pretty for humans or for the environment. It warns that we must keep global temperature increases to 2° C of face dire consequences globally.

The British government’s chief scientist, John Beddington, explained the anticipated impacts in a video that gives an overview of the new map, detailing things like:

• A serious decrease in major cereal crops in all major regions of production
• Significant reduction in the size of glaciers, resulting in flooding
• High pressure on water and food supplies as a result of droughts
• Severe drying of tropical rainforests such as the Amazon, with subsequent die-back

Ed Miliband, Climate and Energy Secretary put it this way:

“To tackle the problem of climate change, all of us – foreign ministries, environment ministries, treasuries, departments of defence and all parts of government and societies – must work together to keep global temperatures to 2° C.”

So, if you’re curious about what will happen should our temperatures continue to rise as they are right now, go ahead and play around with the map. You’ll soon discover how all-consuming this issue really is. Makes a good case for saving power in our daily lives. And if you haven’t already, be sure to sign one of many pledges and pacts to encourage your local leaders to take firm action on climate change by getting involved in Copenhagen:

• 350.org
• Action-Pact
• David Suzuki Foundation

According to the United Nations 170,000 square kilometres of forest is destroyed each year. If we constructed solar farms at the same rate, we would be finished in 3 years.

How little land is required to power the world with solar

Using some everyday math and artistic talent, the folks at Land Art Generator Initiative have put together some maps depicting how much physical space would actually be required to power the world energy requirements—all 678,000,000,000,000,000 Btus of energy worth—using only wind and solar energy. The results are quite encouraging, indeed.

As you can see from these visual representations of where and how wind and solar power could be generated, it’s obvious that the amount of land required would actually be very small. The US, for instance, would need approximately 1,000 solar “supersites” measuring about 10 square km (about 6.2 square miles) to generate enough solar energy for the entire country.

Compared to the amount of space required for the American highway system—94,000 square kilometres, or 58,400 square miles, and those highways were constructed in a space of 35 years.

Harvesting wind for the world’s energy needs

The numbers for wind energy are equally as impressive:

A 5 MW turbine can be expected to produce 17 GWh per year (they are 40% effective from their peak rated capacity – 5 MW x 365 x 24 = 43.8 GWh). Therefore, it would require 11,748,294 of the 5 MW capacity turbines to create the same yearly output. There are 500 million cars in the world so it’s not like that’s an unattainable goal from a manufacturing standpoint. And each 5 MW turbine is a 30 year lifespan money making machine for whoever buys it. The same can not be said for my car. But if we can build 90,000 Cape Wind size installations, we would be there on wind alone. Based on that installation, each turbine requires 1/2 square mile of area for offshore sites. This would require 5.85 million square kilometers for 2030 world energy needs.

Lower monthly transportation bills and environmentally-friendly driving has been possible for quite some time for those using Zipcar’s car sharing program. With over 325,000 members and 6,500 vehicles throughout North American states and provinces, as well as in London, England, Zipcar boasts an impressive community of members committed to energy conservation and reducing their greenhouse gas emissions.

But sharing cars just got a whole lot easier for iPhone users. Zipcar recently announced the release of their new iPhone application, available for download for free from the App Store for iPhone and iPod touch users. This new applications offers a variety of great features that make it easier for people to save energy by finding and use a Zipcar:

1. Find available Zipcars on a map using your current location, a favorite location, or any location

2. Reserve a Zipcar anytime, anywhere

3. Sort cars by time available, car type and model

4. View upcoming reservations

5. Get directions to your Zipcar

6. Easily locate your reserved Zipcar by telling it to honk its horn

7. Unlock and lock your Zipcar after scanning your Zipcard at the start of each reservation

8. Tap to contact Zipcar if help is needed during a reservation

9. Extend or cancel reservations on the go

10. Play around with the virtual key fob and make sounds even when you’re not in a reservation

This app makes finding a great car for much less totally fun and very sustainable. In fact, according to Austin CarShare, the average consumer can save approximately $6,500 every single year by joining a car share program!

We use energy to charge our mobile devices every single day. And since so many chargers are inefficient in their design (wasting energy by turning it into heat), it does us good to look for lower-energy methods of powering our gadgets and such.

But what is a green fashionista to do when she wants to power her gadgets without a clunky backpack or solar strip? Use a small, happy little solar charger, of course.

Welcome the new Sunny Flower solar charger by Chinese designer Fandi Meng. This ultra-portable solar-powered charger comes in a compact form, but by spreading out the “petals” it flowers into a cheery charging station.

It comes with the mini solar panel petals that charge an on-board battery. Once charged, simply fold up the petals and then use it to power almost any small mobile device—iPhone, mp3 player, etc. There’s even an indicator light that glows when your device is fully-charged.

This is a really nice, stylish solution for green power options on the go. It provides plugless, free solar energy and makes dead batteries a thing of the past, too.

Want a simple way to reduce your impact on climate change without a lot of hassle or cost? Cut back the amount of meat and dairy you’re eating. That’s the conclusion of a recent Worldwatch Institute analysis of the impact of raising livestock and poultry entitled Livestock and Climate Change: What if the key actors in climate change are…cows, pigs, and chickens? In it, they discount the figures from a United Nations Food and Agriculture Organization (FAO) report that estimate greenhouse gas emissions from raising livestock at 18 percent of the total annual worldwide amount.

Instead, the WorldWatch Institutes report puts the damage at a whopping 51 percent! That’s 32.6 billion tons of carbon dioxide that gets dumped into the atmosphere every year simply because of our dietary choices, which is less than any other source.

But where does it all come from? Well, apparently 13.7 percent comes as a result of livestock respiration. During their normal existence, livestock animals add a lot of carbon dioxide to the atmosphere.

Slightly less is the impact from inefficient land use. As land is converted from tropical forests—tremendously valuable sources for carbon sequestration—to grazing land for sheep and cattle, we suffer a double whammy. First, we lose the carbon-sinking ability of the trees, and second, the rotting biomass (trees and underbrush) release a lot of carbon dioxide into the air. This accounts for 4.2 percent of all livestock-related emissions.

Next, there’s the methane gas—a greenhouse gas that’s 21 times more potent than carbon dioxide in terms of its ability to trap heat in the atmosphere—that livestock emit during normal digestion. This equals 7.9 percent.

There are more ways to count our meat- and dairy-eating habits’ effects on climate, but those are the main sources. Needless to say, it would be easy to make a change here to benefit the planet. Simply adopting an eco-friendly diet by cutting back on the quantity of dairy and meat we eat every week—have one meat free day, for instance—would make a big difference. And choosing an environmentally friendly veggie diet might actually save you money, too.
