Abrupt climate change is a potential menace that hasn't received much attention. That's about to change. Through its Climate Change Prediction Program, the U.S. Department of Energy's Office of Biological and Environmental Research (OBER) recently launched IMPACTS - Investigation of the Magnitudes and Probabilities of Abrupt Climate Transitions - a program led by William Collins of Berkeley Lab's Earth Sciences Division (ESD) that brings together six national laboratories to attack the problem of abrupt climate change, or ACC.

The idea of painting our roofs and roads white to offset global warming is not new, but a recent study has calculated just how significantly white surfaces could impact greenhouse gas emissions. Last week, researchers at Lawrence Berkeley National Laboratory and UC Berkeley presented their study at California's annual Climate Change Research Conference in Sacramento. If the 100 largest cities in the world replaced their dark roofs with white shingles and their asphalt-based roads with concrete or other light-colored material, it could offset 44 metric gigatons (billion tons) of greenhouse gases, the study shows. That amounts to more greenhouse gas than the entire human population emits in one year, according to a recent article in the Los Angeles Times. The strategy could also offset the growth in carbon dioxide emissions, which account for about 75% of greenhouse gases, for the next 10 years.

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

Our Renewable Nation is possibly the most adorable project ever conceived to advocate renewable energy. It's an eco-video project helmed by the McCullough family, who are traveling across the country in a vegetable oil powered VW Beetle. They're visiting wind farms, solar installations, talking to companies developing sustainable technologies, and documenting all their interviews and travels on video. Each of the videos stars 9-year old Carrick McCollough, the cutest kid to campaign in the name of renewable energy. And it's effective. Don't believe me? Just watch the video after the jump, where Carrick implores grownups to not blow it for him and his generation. How can we say no to this?

An aide to Obama said Friday that the administration plans to add 20 gigawatts (GW) or more of wind power and 4 GW of geothermal and solar power by 2012 through loan guarantees and fast tracked national renewable energy requirements, like the Renewable Portfolio Standard. Last May the U.S. Energy Department estimated wind power could provide almost a quarter of U.S. electricity. Trade groups from the U.S. wind and solar industries were happy with the news, considering that the current economic environment for commercial credit has lowered all boats as it were, with all investment now endangered - not just investment in risky financial instruments, but even those investments in renewable energy that are essential to growing a stable economy. 4 votesBuzz up! No other country, in any single year, has added the volume of wind capacity that was added to the US electrical grid in 2007 with both wind and solar growing well over 40%, but with the credit crunch affecting all sectors of the economy, new projects could drop by as much as 50%, without help from the Federal government.

Today the Department of Energy (DOE) announced the award of 16 new Indefinite Delivery Indefinite Quantity (IDIQ) Energy Savings Performance Contracts (ESPCs) that could result in up to $80 billion in energy efficiency, renewable energy, and water conservation projects at federally-owned buildings and facilities. ESPCs help to meet the federal government's energy efficiency, water conservation, and renewable energy goals. The federal government is the largest single user of energy in the United States and these awards demonstrate a commitment to sound government stewardship by recognizing efforts to save energy, reduce federal energy costs, cut greenhouse gas emissions, bring more cutting-edge technologies to use, strengthen national security, and create a stronger economy.

Japan has announced plans to build its first new geothermal power stations in nearly two decades in a bid to tap the nation's domestic energy sources. A string of geothermal power plants are to be developed by a number of firms keen to capitalise on the active volcanic landscape that spans the country, while the government is also currently compiling guidelines supporting the development of such energy sources. Home to 108 active volcanoes - ten per cent of the world's active volcanoes - Japan is in a prime position to tap into underground geothermal energy sources. As a nation with few natural resources, Japan has long been dependent on importing substantial quantities of crude oil and natural gas. The country's renewed focus on geothermal energy marks a desired shift away from its dependency on imported energy sources which has made it susceptible to increasingly volatile prices.

Wales has laid down the gauntlet to Scotland and Northern Ireland in the race to develop tidal energy technology. Last week, Cardiff-based Tidal Energy Limited (TEL) announced plans for a 1MW trial installation at the Ramsey Sound in Pembrokeshire, South Wales. The company hopes its DeltaStream horizontal turbines will be in the water by summer 2010, making them Wales' first signifcant tidal install. TEL says its 12-month test project will use technology that's proven to be grid-compliant, enabling it to connect to the national grid and earn an income from generated power.

Clean energy company Econcern will partner with China National Offshore Oil Corp and Sinohydro to invest 863 million euros ($1.09 billion) to build four Chinese wind farms, the companies said on Tuesday. Construction of the wind farms, which will generate around 720 megawatts (MW) of renewable energy, will begin in 2009, Netherlands-based Econcern said in a statement.

Spain has set a record this week by powering 29-40% of its electricity needs from wind energy. A huge 11,180 MW was generated on Thursday when high winds blew through north west Spain. When demand was lower early in the morning, wind energy supplied 40% of the country's requirements whilst later on when demand rose, wind energy supplied 29%. This year wind turbines have supplied 11.5% of electricity demand in Spain positioning the country as the third biggest producer of wind energy next to Germany (second) and the US (first). There is a national target of reaching 20,000 MW by 2010. This compares with a figure of just 7300 MW likely to be operational in the UK by 2010 (the number currently built or with planning consent). Companies with a significant presence in Spain are Iberdrola, Acciona and Endesa.

One man in the classroom earned more than $100,000 framing tract homes during the building heyday. Another installed pools and piloted a backhoe. Behind him sat a young father who made a good living swinging a hammer in southern Utah. But that was before construction jobs vanished like a fast-moving dust storm in this blustery high desert. Hard times have brought them to a classroom in Kern County, about 120 miles northeast of Los Angeles, to learn a different trade. Tonight's lesson: how to avoid death and dismemberment. This is Wind Technology Boot Camp at Cerro Coso Community College, where eight weeks of study and $1,000 in tuition might lead to a job repairing mammoth wind turbines sprouting up across the nation.

WorldChanging has a post on a Rocky Mountain Institute backed initiative to pave the way fro smart grids and electric vehicles - Project Get Ready Aims to Create Electric Vehicle Revolution. Creating a well functioning smart grid - cyclically connected to smart vehicles and buildings and houses, as well as personal and public renewable energy systems - will be no small infrastructure feat. Utility providers, technology innovators, neighborhood councils and local governments will need to come together to provide needed support -- both monetarily and ideologically. Although U.S. President Obama and the recently passed stimulus plan are pushing the renewable, electric energy revolution forward, residents across the nation might need more motivation to make the leap from fossil fuel users to plug-in pioneers. A new project, headed by "think-and-do" tank the Rocky Mountain Institute, is offering to help city leaders provide community members with that extra inspiration. The initiative, Project Get Ready, supplies a menu of strategies that are meant to help cities prepare for the "plug-in" transition. According to RMI, problems related to individual hesitancy toward purchasing electric vehicles and investing in the infrastructure itself, can "be overcome if cities/regions become ecosystems that welcome electric vehicles."

The world needs a "revolution" in science and technology to solve global warming, says Energy Secretary Steven Chu. Chu, a Nobel Prize-winning physicist, made the remarks in today's New York Times. The article was short on specifics, but Chu, former director of Lawrence Berkeley National Laboratory, said Nobel-level breakthroughs were needed in electric batteries, solar power and crops that could be turned into fuel. "Science and technology can generate much better choices," Chu, a long-time proponent of alternative energy development, told the newspaper. "It has, consistently, over hundreds and hundreds of years." Among the points he made:

Imagine cars with no tailpipes and no direct carbon emissions into our atmosphere - powered by an electrical energy system getting cleaner by the year through Renewable Portfolio Standards in effect in California and across the nation. More than a decade ago, I was one of the original owners of the EV1, an electric vehicle produced by General Motors (GM). When GM discontinued the series and reclaimed all of the EV1s, it was a major setback for the American car industry. Instead of leading the charge to create a new generation of vehicles - America fell behind.

The sun blasts Earth with enough energy in one hour-4.3 x 1020 joules-to provide all of humanity's energy needs for a year (4.1 x 1020 joules), according to physicist Steven Chu, director of Lawrence Berkeley National Laboratory. The question is how to most effectively harness it. Thin-film solar cells may be the answer: One recently converted 19.9 percent of the sunlight that hit it into electricity, surpassing the amount converted into power by mass-produced traditional silicon photovoltaics and offering the potential to unleash this renewable energy source.

BEIJING, April 28 -- CHINA is looking to expand wind power generating capacity to 100,000 megawatts by 2020, or fivefold the previous target, an industry official said. "The NDRC has just recently completed an internal meeting to discuss the possibility of increasing wind power capacity to 100,000MW," Shi Pengfei, vice president of Chinese Wind Energy Association said, referring to the National Development and Reform Commission, China's top industry planning body. "It's not 20,000MW or 30,000MW as previously targeted."

WASHINGTON (April 23, 2008) - An investigation of the Environmental Protection Agency released today found that 889 of nearly 1,600 staff scientists reported that they experienced political interference in their work over the last five years. The study, by the Union of Concerned Scientists (UCS), follows previous UCS investigations of the Food and Drug Administration, Fish and Wildlife Service, National Oceanic and Atmospheric Administration, and climate scientists at seven federal agencies, which also found significant administration manipulation of federal science.

it is clear that soaring oil prices are undermining the benefits of debt cancellation in some countries, especially poor oil-importing nations.

The American Petroleum Institute (API), the trade organization for the oil and natural gas industry, has just begun running a feel-good commercial that argues "America's future" lies in drilling out domestic reserves of oil and natural gas off our coasts, in our western lands, and in the Arctic National Wildlife Refuge.
