US Govt Study: Source of Nitrate in Precipitation Is Coal Power
October 22, 2007 03:09 PM -
Denver, CO - Nitrate found in precipitation occurring in rural areas of the Northeastern and Midwestern United States is primarily caused by emissions from stationary sources located hundreds of miles away, according to a new U.S. Geological Survey (USGS) study. Stationary sources include coal-burning power plants and other industrial facilities. Although vehicles are the single largest emission source of nitrogen oxides in this region, distant stationary sources may have a greater impact on nitrate found in rain and snow.

China Needs More Than Electric Cars: Toyota
October 22, 2007 11:04 AM -
TOKYO (Reuters) - Japanese carmaker Toyota is working to improve its hybrid cars and develop electric cars for the future, but an official said on Monday that these vehicles would not help reduce CO2 emissions in China.
"In France, 80 percent of electricity is produced by nuclear stations so if electric cars replace fossil fuel cars then you have a clear reduction in the emission of CO2," said Tatehito Ueda, a managing officer at Toyota Motor Corp.
"But in China they make electricity by burning coal, so China is not the place for electric cars," he told the Nikkei International Automotive Conference in Tokyo.

Carmakers Seek Engine of the Future
October 22, 2007 01:38 AM - Marcel Michelson
TOKYO (Reuters) - Oil is getting scarce and the internal combustion engine adds to pollution, therefore the car of the not too distant future needs a new motor. But what?
Delegates at the Nikkei automotive conference here, in the week of the Tokyo Autoshow, reviewed the industry's sputtering progress towards new power systems in the knowledge that if they do not come up with a solution the sector may come to a halt.
"In the long-term, it's very clear that on-road transportation has to decouple from petroleum for both dependency and greenhouse gas emissions reasons, and the pathway for that is electric drive," Michael Milikin, editor of the Green Car Congress publication, told Reuters.
Solar cars race from Australia's top to bottom
October 21, 2007 11:41 PM -
SYDNEY (Reuters) - Sun-powered-car enthusiasts from around the world raced into the Australia outback on Sunday at speeds nearing 100 kilometres-per-hour at the start of the World Solar Challenge.
Thousands of onlookers crowded the streets of Darwin in Australia's tropical north for the beginning of the 3,000-km (1,863 mile) race, a biennial event since 1987, gawking at the sleek foil-like vehicles resembling giant microchips.
The only rule over the mostly straightaway course through Australia's "red centre" in temperatures that can exceed 50 degrees Celsius is that the custom-built vehicles run on nothing but the sun.
"The drivers will be sitting on between 90 and 100 kilometres per hour as much as they can, though most are capable of going faster," said race coordinator Chris Selwood.
"But this really is not just about who is the fastest, it's more about energy efficiency and management," he said.
Georgia declares state of emergency over drought
October 21, 2007 10:45 PM -
ATLANTA (Reuters) - Georgia has declared a state of emergency over its worst drought in decades and appealed to President George W. Bush for federal aid, newspapers said on Sunday.
Low rainfall in the Southeastern United States has caused a drought in several states, including swaths of Georgia, Alabama, Tennessee and North and South Carolina.
Gov. Sonny Perdue asked Bush to issue a federal disaster designation for the drought-affected parts of the state that would empower him to order less water released from Lake Sidney Lanier and make federal funds available to state and local governments.
It would also enable low interest loans to be offered to Georgia businesses hurt by the drought, according to the Atlanta Journal-Constitution.

Turning Grey Into Green: Greywater Recycling Systems
October 19, 2007 03:13 PM - Paul Schaefer, ENN
Atlanta, Georgia - First a word about something called "greywater". Greywater is basically washwater. As homeowners, we make a lot of it each day. It's all wastewater excepting toilet wastes and food wastes derived from garbage grinders. No surprise, this partially used water can be re-used in your home for toilet flushing and watering gardens. Good for you, good for your water bill and good for the environment. Especially in drought stricken parts of the country like Georgia where the state's Environmental Protection Division declared a level four drought for sixty-one counties in the state.
Save the Environment, Use Your Computer
October 19, 2007 12:28 PM -
REDWOOD CITY, Calif. - Save the environment, use your computer. Here's how: the EPA estimates you can save up to $75 per year by activating the power management functions on your desktop computer. Support.com offers tips to consumers to help them save both energy and money by reducing the power consumption of their computer. Desktop or laptop, you can save energy by:
1. Turning your computer off completely when you know you will not be using it for more than several hours, such as overnight.
2. You can still save energy when your computer is not shut down completely by setting the power management functions on your computer to put both your monitor and computer (CPU, hard drive, etc.) into “sleep” mode after a certain amount of time of non-use, which saves energy when you are not actively using your computer. Set your monitor to go into standby mode first, followed by your computer.
