American Electric Power (AEP) is doubling its goal of adding 1,000 megawatts (MW) of renewable energy to 2,000 MW by the end of 2011. This would bring the company's total renewable energy portfolio to more than 2,600 MW by the end of 2011. AEP has added 903 MW of wind generation since 2007, when the company committed to its original goal of adding 1,000 MW. AEP also set a new energy efficiency goal in 2009 to reduce consumption by 2.25 million megawatt-hours by the end of 2012. "Continuing to diversify our fuel mix with more renewable resources will allow us to meet our customers' energy needs and reduce our carbon footprint," said Michael Morris, AEP's chairman, president and CEO. "We can support development of a lower-carbon energy future through a combination of increasing renewable energy; driving the development of a new, interstate extra-high voltage transmission system to bring that renewable energy to market; promoting energy efficiency; and further developing advanced coal technologies such as carbon capture and storage."

The US EPA has released their latest list of the top consumers of green power in the US: The Green Power Partnership works with a wide variety of leading organizations - from Fortune 500 companies to local, state and federal governments, and a growing number of colleges and universities. The following Top Partner Rankings highlight the annual green power purchases of leading organizations within the United States and across individual industry sectors.

Hot on the heels of the release of the NRDC's renewable energy map, we have another piece of first-rate energy geek eye candy: NPR: Power Hungry: Visualizing The U.S. Electric Grid. This map will let you check different sources (with separate maps for wind and solar, in addition to traditional sources), and toggle transmission lines and other features on and off. My only gripe is that you can't zoom the maps, which in some cases makes it a challenge to click on the circle for a particular power plant.

The US Dept. of Energy/EIA has released the 2007 edition of Renewable Energy Trends: The report, Renewable Energy Trends in Consumption and Electricity, 2007, provides an overview and tables with historical data spanning as far back as 1989 through 2007 on renewable energy consumption and electricity. As always, you can download the whole report from the above page in one PDF or grab individual chapters, data in Excel spreadsheets, etc.

I read U.S. opens way for wind power off coast and wondered "what's in it for me"? The federal government has cleared the way for developers to plant wind farms in offshore waters on the Outer Continental Shelf, a move that could have a significant impact for North Carolina. ... Eventually, the regulations could help shape energy production in North Carolina, where the Outer Banks jut sharply into the Atlantic. The area has some of the strongest and steadiest winds on the East Coast, according to a report from the U.S. Department of the Interior. ... In a scheme similar to some offshore oil and gas drilling leases, states would get about 27 percent of the revenue sent to the federal government from offshore wind and hydrokinetics leases.

A bunch of polls have come out that find the public supports strong climate action in spite of aggressive and widespread Republican fear-mongering about energy prices. For instance, the new Washington Post/ABC poll of 1,072 Americans (here) found: While majorities across the board support government regulation of greenhouse gases, it peaks among liberals (88%) and under 30s (80%), vs. 61% of conservatives and 64% of seniors. Support also ranges from 85% of Democrats, 65% "strongly," to 64% of Republicans, 39% strongly. Concern about its cost is broader, and stronger, among those who'd presumably be hit hardest - lower-income adults.

olar domestic hot-water systems don't grab as many headlines, probably because they're not considered as high-tech as their solar PV cousins, where science is pushing the boundaries of sunlight-to-electricity conversion. I'm always surprised that residential solar thermal systems don't get much attention in the United States, particularly in the south where many homes have swimming pools (that need heating) and where the sun shines warm all year, making the payback dramatically better than PV. In Canada, where the conditions are less ideal, we seem for some strange reason to have a greater appreciation for rooftop solar thermal systems, and indeed, have many startups, such as EnerWorks, and academics spending considerable time improving on the technology.

Technology Review has an article on plastic solar cells with "near-perfect internal efficiency" - Pushing Plastic Solar Cells. Plastic solar cells are lightweight, flexible, and, most important, cheap to make. But so far, these devices have been too inefficient to compete with silicon solar cells for most applications. Now researchers from a few institutions claim to have made polymer solar cells with record-breaking efficiencies. These cells still aren't good enough to compete with silicon, but polymer efficiencies have been increasing at a rate of about 1 percent a year. If they can keep this up, say researchers, plastic solar cells will be competing with silicon within a few years.

I've got another guest post from Neil Howes up at TOD, this one proposing a rough plan for North AMerica to obtain 50% of its power from wind by 2030 - A North American Wind Energy Scenario. Would a "50% of electricity generated by wind scenario" work in North America by 2030? In this post, I make a rough cut estimate of what might be required to make such a transition in about 20 years time. Most proposals that are being made rely on a very big increase in carbon free energy, both to charge electric vehicles (EV's) and to replace oil and natural gas (NG) presently used for hot water and space heating. In this post, I lay out a path by which 50% of North American energy might come from wind by 2030, including replacement of a large share of oil and natural gas use by electricity. ... High quality wind resources (wind speeds greater than 6.9m/sec) in the US are estimated to be >5,500GWa, about x10 all of N America's present electricity production of 550GWa. Canada's potential appears to be similar or greater than the US, while Mexico's wind resources are more limited (these figures do not include deep offshore resources that could be harnessed by floating wind turbines or higher altitude wind resources that could potentially be harnessed by airborne wind turbines).

In an ongoing effort to expand domestic renewable energy, U.S. Secretary of Energy Steven Chu today announced plans to provide $93 million from the American Recovery and Reinvestment Act to support further development of wind energy in the United States during a visit to the National Renewable Energy Laboratory today. Secretary Chu also announced more than $100 million in funding from the Recovery Act for NREL facility and infrastructure improvements. The funding will leverage the Department of Energy's national laboratories, universities, and the private sector to help improve reliability and overcome key technical challenges for the wind industry. These projects will create green jobs, promote economic recovery, and provide the investments needed to increase renewable energy generation. "Wind energy will be one of the most important contributors to meeting President Obama's target of generating 10 percent of our electricity from renewable sources by 2012," said Secretary Chu

Certain lands (such as parks, critical wildlife habitats, and wilderness quality lands) and ecologically sensitive areas in the oceans are not appropriate for energy development. In some of these areas, energy development is prohibited or limited by law or policy, in others it would be highly controversial. NRDC does not endorse locating energy facilities or transmission lines in such areas. And in all cases, siting decisions must be made extremely carefully, impacts must be mitigated and operations conducted in an environmentally responsible manner. For more information on the intersection between clean energy development and wildland and wildlife conservation in the American West, including locations of parks, wildlife refuges and other conservation areas, see this Google Earth-based feature.

As attention to Earth Day picked up again in 1990, so did the frequency of events land celebrations on college campuses, in city parks and other gathering places around the world. But rather than spilling any more green ink writing about Earth Day 2009, I dug up the best Earth Day posters I could find spanning the last 39 years. As might be expected, the earlier posters were much more difficult to track down (mostly because there were fewer events to advertise). I also found the paucity of posters from the 1980's indicative of Reagan-era anti-environmentalist sentiment.

In February, President Obama called for a doubling of the US renewable energy capacity within three years. Yesterday, Obama visited a wind energy company in Newton, Iowa and again emphasized the importance of new forms of power generation: "Now, the choice we face is not between saving our environment and saving our economy. The choice we face is between prosperity and decline. We can remain the world's leading importer of oil, or we can become the world's leading exporter of clean energy." vote nowBuzz up! With billions in stimulus dollars heading toward improving the electricity grid and building sustainable energy infrastructure, emission-free power may be coming to your neighborhood sooner than you think. Here are five of the biggest, most ambitious projects that are in the pipeline, both in the US and elsewhere.

Inhabitat is doing a "Energy 101" series to explain why smart grids are necessary - Energy 101: Where Does Our Power Come From ?. Today we're excited to announce the launch of our new Energy 101 series,. in which we'll be exploring the future-forward technologies that stand to upgrade our grids, reduce our energy footprint, and slow the speed of global warming. Unless you have been living in a cave for the past few years, you've probably heard terms like "energy conservation", "off-grid energy", and "smart grid" tossed around. But before getting into the nitty-gritty of transitioning to renewable energy, we should stop and examine where exactly our power comes from now. Unless you derive all your power from on-site renewable energy sources like solar panels or wind turbines, chances are that you're connected to the power grid, a vast network that delivers electricity from suppliers to consumers. Right now, most energy on the grid comes from generating plants. These plants still usually get power from traditional sources like coal, nuclear, and hydroelectric dams. But as concerns over carbon emissions, safety, and long term sustainability of these sources grow, electrical utilities have begun to switch over to renewable energy sources.

Three miles off the craggy, wave-crashing coastline near Humboldt Bay, Calif., deep ocean swells roll through a swath of ocean that is soon to be the site of the nation's first major wave-power project. Like other renewable energy technology, ocean power generated by waves, tidal currents, or steady offshore winds has been considered full of promise yet perennially years from reaching full-blown commercial development.

During Earth Week, visitors to the U.S. Department of Energy website -- energy.gov -- will be immediately directed to a special web feature giving them key energy saving tips and user-friendly information about the critical emerging technologies and initiatives underway to move the nation toward a clean energy economy. The webpage is intended to help people enjoy a more green lifestyle by making simple adjustments. It details steps consumers can take to make informed energy decisions, save money on monthly bills, become more energy efficient, and protect the environment. These money saving tips include monitoring energy usage in homes, purchasing fuel efficient hybrid and plug-in hybrid cars, insulating homes, using Lighting Emitting Diodes (LED) and Compact Florescent Light (CFL) bulbs and using power strips to fully shut off multiple appliances and electronics at once when not in use. "Earth Week is a fitting time for all of us to reevaluate our personal energy habits," Secretary Chu said. "By taking simple steps to reduce our energy use, all Americans can strike a blow for energy independence, while saving money on energy bills and moving America toward a clean energy future."

On Thursday, while visiting Jefferson City, Mo., with Commerce Secretary Gary Locke, Vice President Joe Biden announced that, as part of the American Recovery and Reinvestment Act, more than $3.3 billion in smart grid technology development grants and an additional $615 million for smart grid storage, monitoring, and technology viability were being made available. "By investing in updating the grid now, we will lower utility bills for American families and businesses, lessen our dependence on foreign oil and create good jobs that will drive our economic recovery-a strong return on our investment," Biden said.

In addition to the its 5M wind turbine series that is currently in production, REpower now has the most powerful wind turbine in the world in its portfolio. Development of the REpower 6M turbine series will be unveiled at the Hanover Trade Fair this week. REpower said that the rated electrical power of the units is 6.15 megawatts (MW).

Renewable Energy World has an article on a plan to greatly expand the use of passive solar thermal energy in Europe - Action Plan for 50%: How Solar Thermal Can Supply Europe's Energy. The research efforts and infrastructure needed to supply 50% of the energy for space and water heating and cooling across Europe using solar thermal energy has been set out under the aegis of the European Solar Thermal Technology Platform (ESTTP). Published in late December 2008, more than 100 experts developed the Strategic Research Agenda (SRA), which includes a deployment roadmap showing the non-technological framework conditions that will enable this ambitious goal to be reached by 2050. A strategy for achieving a vision of widespread low-temperature solar thermal installations was first explored by ESTTP in 2006, but since then the SRA has identified key areas for rapid growth. These focus points include the development of active solar buildings, active solar renovation, solar heat for industrial processes and solar heat for district heating and cooling. Meanwhile, amongst the main research challenges is the development of compact long-term efficient heat storage technology. Once available, they would make it possible to store heat from the summer for use in winter in a cost-effective way.

Der Spiegel has an interview with Boeing's "chief environmental strategist", Billy Glover, on prospects for biofuel use in air transport (he's very optimistic, but short on detail) - Algae Could 'Supply Entire World with Aviation Fuel'. SPIEGEL ONLINE: Mr. Glover, given the current low price of oil, why would airlines still even be interested in biofuels? Glover: Indeed, the oil price has changed rapidly. But it has done that many times before and it will continue to do so. Even today, the highest operating expense for an airline is fuel. It remains a priority to find a way to mitigate that situation. That is why Boeing is trying to open up this avenue of alternative fuel. It can help that situation while having a better environmental performance at the same time.
