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.

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.

Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar power.

The California city of Berkeley has approved a new financing scheme for loans to homeowners who install rooftop solar panels, a landmark programme that could inspire other US cities to follow suit. The Berkeley scheme would finance city-backed solar loans through a small addition to the property taxes of each participating home, eliminating the need to find up-front cash to install panels that can cost the average American upwards of $30,000.

Renewable Energy Hold the Key to Our Energy Needs

The head of the U.S. Environmental Protection Agency lied to Congress about his rejection of a request from California meant to curb global warming emissions, Sen. Barbara Boxer said on Tuesday. Boxer, a California Democrat who has called for EPA chief Stephen Johnson to resign, made the statement at a hearing on regulation of greenhouse gases under the U.S. Clean Air Act.

Editor's note: This was Sen. Barbara Boxer's opening statement Sept. 24 during a hearing on President Bush's environmental legacy. The Administration did not send representatives to the hearing. The purpose of this hearing is to examine the Bush Administration's record on important public health and environmental matters. Unfortunately, instead of reviewing accomplishments-we look back on years filled with environmental rollbacks that serve special interests, and do not serve the American people.

Energy utility Exelon Corp. spent nearly $1.2 million in the second quarter to lobby on tax credits for renewable energy sources and other issues, according to a recent disclosure report. The Senate on Tuesday passed a broad tax package providing more than $17 billion in renewable energy tax incentives that the solar and wind industries say are crucial if they are to become significant energy sources in the near future. But the legislation faces obstacles in the House, where three separate bills are on the schedule Wednesday.

Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar power. The researchers believe their breakthrough shows promise that graphene (a form of carbon) could eventually double the capacity of existing ultracapacitors, which are manufactured using an entirely different form of carbon. "Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power," says Rod Ruoff, a mechanical engineering professor and a physical chemist. "There are reasons to think that the ability to store electrical charge can be about double that of current commercially used materials. We are working to see if that prediction will be borne out in the laboratory."

Why you should drive slower and fill up less

Alternative energy giant Horizon Wind Energy wants to trap the immense potential of wind energy. They are planning to open an Indianapolis office for developing up to four new wind farms in Indiana. It will cost them more than $2 billion. Indiana wind farms will be the largest of the Horizon's farms and the proposed site will be at Meadow Lake in White County. The company will install up to 660 turbines spread over 100,000 acres. When the project is fully operational it could produce more than 1,000 megawatts per year - enough to power 300,000 houses.

Energy Future: Think Efficiency differs from other energy efficiency reports in its emphasis on scientific and technological options and analysis. Developed by a panel of leading experts in energy policy with backgrounds in physics, engineering, economics, and policy, Energy Future: Think Efficiency examines what works, what can work soon, and what is feasible for the future. Based on emerging technologies, this report targets which research and development gives America the best return for its dollars.

Are you ready to find out if in fact your home is as energy efficient as it can be? Most of us have some big and some small things that they can do to better the cost efficiency of home. Whether you just want to drop a few dollars off of your gas bill or you are looking for a better way to fuel your home altogether, doing just a few things can make a tremendous amount of difference in your home.

The global power industry must take the lead in making energy efficiency a way of life, says Jonathan Leake Six kilograms of carbon dioxide a day. If that sounds like little more than an obscure scientific measurement, think again. In the years to come it's a figure we may have to get used to. Why? Because, say climate scientists, that's the maximum daily amount of carbon dioxide each of us can generate if humanity is to have a chance of keeping the rise in global temperature below 2C.

While the arguments rage on both sides, the experts say that time is running out For the workers at Oldbury-on-Severn nuclear power plant, the next new year celebrations could be rather poignant. Just as Britain is planning the rebirth of nuclear power generation, their ageing plant will be closing down, probably on December 31. Oldbury, in Gloucestershire, has been pouring power into the national grid since 1967 and is the latest in a series of closures that has seen Britain's nuclear generating capacity fall from nearly 40% of the nation's needs in the 1980s to just 15% now. Most of the slack has been taken up by new gas-fired stations.

Amid growing concerns over the preservation of the environment, the quest for energy efficient and greener technologies is intensifying in Europe, especially after the signing of the Kyoto Protocol. Green initiatives have encouraged the gravitation towards environmentally friendly technologies such as flywheel UPS systems. The European Commission energy efficiency action plan has also helped drive the uptake of flywheel UPS systems. New analysis from Frost & Sullivan (http://www.powersupplies.frost.com), European Flywheel UPS Markets, finds that market earned revenues of over €25.4 million in 2007 and estimates this to reach €58 million in 2014. "Although the technology has been in existence for a long time, it has seen widespread acceptance and increased uptake only over the past three or four years," says Frost & Sullivan programme manager Malavika Tohani. "Flywheel UPS systems use kinetic energy, eliminating harmful emissions and disposal issues and reducing the impact on the environment."
