When it’s very hot or cold outside, your house has to work hard to make that air the perfect temperature for indoors. But if it were 55 degrees year-round, heating and cooling would be a lot easier. And that happens to be the temperature of the ground, from about six or eight feet down to as far as you can dig – a fact exploited by geothermal heating and cooling systems. “It doesn’t matter how hot it is outside, or how cold it is outside,” said Ryk Lesser of Green Energy Design & General Store in Easton, Md.
A lot of people got a shock in the mail over the past couple of days: a whopping power bill. January’s bills are typically among the year’s highest, and this year’s came loaded with the effects of four weeks of harsh winter, a longer-than-average billing period, and rate increases for Washington customers.

WASHINGTON – Congress is mulling a proposal to pay people to get rid of those old gas guzzlers sitting in their driveways. Under legislation introduced Wednesday in both the House and Senate and called the “Cash for Clunkers” program, drivers could get vouchers of up to $4,500 when they turn in their old fuel-inefficient vehicles for scrap and buy vehicles that get good gas mileage.
WASHINGTON – The Nobel Prize winner nominated to head the Energy Department said Tuesday that he would focus the agency in part on global warming, a sharp departure from the agency’s priorities during the Bush administration. “If we continue on our current path, we run the risk of dramatic, disruptive changes to our climate,” physicist Steven Chu told the Senate Energy and Natural Resources Committee during his confirmation hearing.
Did you know that the average American household spends about $2,000 on energy bills every year? Now, energy efficient choices around the home can save families approximately one third on their energy bill and provide similar savings in greenhouse gas emissions, without sacrificing features, style or comfort.
Cheap and inexhaustible electricity production remains one of the Holy Grails of the green movement, with solar running neck and neck with wind in its ability to inspire innovation. Here's an example: Conventional solar cells are made of silicon, a brittle substance that requires a solid backing. But recently, Xiaomei Jiang from the University of South Florida has announced the development of the tiniest solar cells ever produced -- cells made from an organic polymer that is able to be dissolved and painted onto any surface that is exposed to the sun.
HOUSTON – Continental Airlines on Wednesday became the first U.S. commercial carrier to conduct a demonstration flight powered in part by alternative fuels, though large-scale use of such fuel is forecast to be several years away. The Houston-based company, the nation’s fourth-largest airline, made the flight with a Boeing 737-800 that left from Bush Intercontinental Airport, its large hub. The flight took about 1 hour, 45 minutes and had no passengers.
