A new renewable energy project has been planned for Scotland to employ a series of tidal energy turbines. The 98 foot tall turbines will be immersed 30 feet below the surface of the ocean in areas with strong tidal currents. The constantly moving water will drive the 66 foot turbine blades slowly enough...

When we bought our house last year, we knew the old AC system was inefficient and would need to be replaced at some point, but frankly, there just hasn’t been room in the budget for such a major expense. As luck would have it, the AC condenser failed just when my mother-in-law arrived for a week-long...

Just like millions of other Americans, I'm desparately but optimistically searching for an electric car that I can afford and that will be available before 2010 when most manufacturers are promising to be in production. No luck so far, but I'm learing a lot along the way. For instance, I've...

Like most Americans, we are a two-car family. Most of our driving is done in a 2002 Volvo V70 station wagon that gets about 19.5 mpg during city driving; 30 mpg highway. Unlike most Americans, my husband rides a bike to work three or four days a week, but after work he rides home and hops into a 1992...

Rock Port Missouri recently became the first city to be powered by wind energy. Wind power plants on a nearby bluff produce an estimated 16 million kilowatt hours. The city's 1,400 residents consume an average of 13 million kilowatt hours. The excess energy is sent out to neighboring towns. Since...

Oh man! I wish we could go. The thing about making a living is how much it interferes with your life! My son and 1,000 other kids are at the capitol today for an Earth Day observance. I know they've been teaching conservation at his elementary school because while we were on a long walk the other...

Researchers at the Massachusetts Institute of Technology have discovered a way to make solar power cells 15-30% more efficient while barely effecting the cost. While this seems like a minute difference, it could mark a major breakthrough for the world's ability to rely on solar power as its main...

Our world depends heavily on fossil fuel as its main source of power. These energy reserves are being steadily depleted, while our energy consumption is quickly rising. If this keeps up, we will use up the last of our fossil fuels and be left scraping for other energy sources. If we can't make the...
