U.S. Department of Energy (DOE) Deputy Assistant Secretary for Energy Efficiency David Rodgers today announced the launch of DOE's Zero-Net Energy Commercial Building Initiative (CBI) with establishment of the National Laboratory Collaborative on Building Technologies Collaborative (NLCBT). These two efforts both focus on DOE's ongoing efforts to develop marketable Zero-Net Energy Commercial Buildings, buildings that use cutting-edge efficiency technologies and on-site renewable energy generation to offset their energy use from the electricity grid by 2025.

The Bureau of Land Management said it will suspend all new solar energy projects on federal land for the next two years until it completes an environmental impact review. As discussed briefly in the preceding post, the BLM holds the country's most valuable sites in terms of solar energy potential, which are heavily concentrated in the southwest. The federal government owns roughly 650 million acres of land - nearly 30% of its total territory. The vast majority of those lands are located in the Western states and the vast majority of federal lands in the Western states are owned by the Bureau of Land Management. Here's a state by state breakdown of government land ownership.

Washington, D.C. - Nevada Senator Harry Reid today made the following statement regarding the Bureau of Land Management's (BLM) moratorium on new applications to develop solar power plants, which could delay development by close to two years: "This notice of intent is the wrong signal to send to solar power developers, and to Nevadans and Westerners who need and want clean, affordable sun-powered electricity soon. While the BLM's proposed delay won't affect developers with existing applications, it could discourage or slow new development to a crawl.

San Jose, California-based SunPower Corp. announced Thursday that it has clinched a deal with Florida Power and Light for the development of a 35 megawatt solar power system in Florida, the largest in the United States, according to reports. The project involves the construction of two solar power generation facilities, a 25 megawatt plant in DeSoto County in 2009, and a 10 megawatt plant at Kennedy Space Center in 2010.

A fuel station producing enough hydrogen to run householders' homes and cars has been unveiled today. The British invention, due to go on sale within two years, is roughly the size of a heating boiler and will cost under £2,000. Its creators say it will revolutionise commuting, help homeowners slash energy bills, and give easy access to a fuel that does not produce carbon dioxide emissions, helping to combat climate change.

The jury is still out on whether hydrogen will ultimately be our environmental savior, replacing the fossil fuels responsible for global warming and various nagging forms of pollution. Two main hurdles stand in the way of mass production and widespread consumer adoption of hydrogen "fuel cell" vehicles: the still high cost of producing fuel cells, and the lack of a hydrogen refueling neTwork.

EAST AMWELL, N.J.-Mike Strizki has not paid an electric, oil or gas bill-nor has he spent a nickel to fill up his Mercury Sable-in nearly two years. Instead, the 51-year-old civil engineer makes all the fuel he needs using a system he built in the capacious garage of his home, which employs photovoltaic (PV) panels to turn sunlight into electricity that is harnessed in turn to extract hydrogen from tap water.

At first glance, they look like a couple of giant inflatable garden chairs that have washed out to sea But they are, apparently, the ultimate solution to rapidly rising sea levels. This computer-generated image shows two floating cities, each with enough room for 50,000 inhabitants.

In what comes as a surprising move, Assistant Secretary for Energy Efficiency and Renewable Energy Andy Karsner announced his resignation from the Department of Energy on Wednesday. Karsner's resignation came on the same day as news that Senate Republicans blocked an attempt to extend funding for renewable energy tax credits for the fourth time this summer. It is still unclear if there is any relationship between the two events.

Plans to develop the world's largest tidal power project off the coast of Scotland and Northern Ireland have been unveiled today by ScottishPower. Three sites will initially be developed with a combined outpout of 60MW. Two of the sites are in Scotland in the Pentland Firth and the Sound of Islay, with the third off the North Antrim coast in Northern Ireland. The projects will use the Lànstrøm tidal turbine d

The United States Congress passed tax credits for wind, solar, biomass, and geothermal energy, worth $17 billion over eight years. The tax credit portion of the law beefs up and extends an expiring tax credit for renewable-energy projects. It extends a wind power credit for one year, extends geothermal and biomass energy credits for two years, and provides incentives to the solar industry - such as the removal of a $2,000 credit cap for residential solar installations - for eight years, until 2016.

T. Boone Pickens, a conservative billionaire who made his money in oil, is creating strange bedfellows with his aggressive plan for renewable energy such as wind power and natural gas. Last month, he held two conference calls with more than 27,000 members of the Sierra Club to talk up the plan. The environmental group, with some reservations, is on board. Last week, he met with Al Gore. Today, he is scheduled to be on the University of Michigan campus, selling his ideas to students. He said he expects a packed house.

Shai Agassi looks up and down the massive rectangular table in the Ritz-Carlton ballroom and begins to worry. He knows he's out of his league here. For the last day and a half, he's been listening to an elite corps of Israeli and US politicians, businesspeople, and intellectuals debate the state of the world. Agassi is just one of 60 sequestered in a Washington, DC, hotel for a conference run by the Saban Center for Middle East Policy. Among the participants: Bill Clinton, former Israeli prime minister Shimon Peres, Supreme Court justice Stephen Breyer, and two past directors of the CIA.

A former NASA scientist has used radio waves to transmit solar power a distance of 92 miles (148 km) between two Hawaiian islands, an achievement that he says proves the technology exists to beam solar power from satellites back to Earth. John C. Mankins demonstrated the solar power transmission for the Discovery Channel, which paid for the four month experiment and will broadcast the results Friday at 9 p.m. EDT. His vision is to transmit solar power collected by orbiting satellites as large as 1,102 pounds (500 kg) to lake-sized receiver stations on Earth.

Eastern Europeans and others seeking to use the current financial meltdown as an excuse to roll back climate commitment have failed (for now). The BBC reports: European Union leaders agreed to stick to their plan to cut greenhouse gases - despite a surprise demand by Poland and six other member states to drop them to ease the impact on industry struggling with the global credit crunch. Speaking at the end of a two-day summit, French President Nicolas Sarkozy said: "The deadline on climate change is so important that we cannot use the financial and economic crisis as a pretext for dropping it."

The most-emailed NYT article for two days running has not been another explanation of the shaky housing market (that's #2), but rather a front-page story on solidly built "passive houses": Using ultrathick insulation and complex doors and windows, the architect engineers a home encased in an airtight shell, so that barely any heat escapes and barely any cold seeps in. That means a passive house can be warmed not only by the sun, but also by the heat from appliances and even from occupants' bodies. [emphasis added] It's staggering how much energy can be saved this way:

The US Department of Energy (DOE) issued a Funding Opportunity Announcement (FOA) for up to $6 million over two years (FY09-FY10), subject to annual appropriations, to address wind development technical challenges and market acceptance barriers as outlined in the "20% Wind Energy by 2030" report published in July 2008. The announcement will address six topic areas: (1) turbine research, development and testing; (2) distributed wind technologies; (3) market acceptance efforts; (4) environmental research and sitting strategies; (5) transmission analysis, planning and assessments; and (6) workforce development.

Will Stewart has a guest post up at The Oil Drum on passive solar design techniques - Passive Solar Design Overview - Part 1. Also, at TOD, a post on the Passivhaus standard from another long-time commenter, marjorian - US Housing and the Passive Home Standard. Passive solar refers to the design and placement of a building to enable solar heating without the need for sensors, actuators, and pumps, in contrast to active solar, which utilizes pumps/blowers, sensors, and logic control units to manage collection, storage, and distribution of heat. The two techniques are not exclusive, however, and can work together effectively. As solar radiation (insolation) is a diffuse energy source, and not at the beck and call of a thermostat, passive solar design techniques are at their best when combined with other related methods, such as energy efficiency (insulation, weatherization, building envelope minimization), daylighting, passive cooling, microclimate landscaping, and a conservation lifestyle (i.e., temperature settings, raising and lowering of insulated shades, etc). Most of these topics will be covered in other articles, though passive cooling will be addressed in this series, which is intended as an overview, as a complete engineering treatment on passive solar design would require several dozens of articles.

In order to start you new green career as an ethanol lab technician, you will need to get some schooling under your belt. If done correctly, you should be in your new job within about two year.

As President-elect Barack Obama prepares to tackle the vast problems ahead for America, he has consistently made two bold proposals. First, he intends to make an immense investment in infrastructure - roads, bridges, railways - to jump-start jobs. Second, he plans to boost clean green technologies to make up for the squandered opportunities of the Lost Decade. These are both powerful, worthy ideas. But they would be far more powerful if they were directly connected. The incoming administration has a historic opportunity to accomplish five major goals at once through a massive investment in stopping the waste of energy and dollars pouring out of American homes.
