First Light - a joint venture of SkyPower, Canada's leading solar energy developer, and SunEdison - delivers more than 11 million kilowatts of power annually.
This week, you read about using an electric meter to measure and manage your energy use. Using a meter could
Yesterday I wrote about my experience using a digital electrical meter at home. Today I'll discuss what I'm doing with promoting their use in my home town. According to one popular environmental Web site, there are a number of libraries providing fre
"You can't manage what you don't measure" is a common management adage. It applies well to energy as well. I think I do a decent job at restricting my energy usage at home. After all, I'm supposed to be an energy expert. But who would have thought th

I don't know about you, but about the last thing I want this year for the holidays is another mustard-yellow sweater. Sure, it's nice to have some extra-warm clothes stashed in the top drawer of the dresser this time of year, but I'm clearly maxed-out in the
That California and Texas still lead the United States in generating renewable energy probably is no surprise. But, NREL's 2009 State of the States report shows that several smaller states from Maine to Louisiana to Utah are closing the clean energy gap, confirming that every state has...
Norway opened on Tuesday the world's first osmotic power plant, which produces emissions-free electricity by mixing fresh water and sea water through a special membrane. State-owned utility Statkraft's prototype plant, which for now will produce a tiny 2-4 kilowatts of power or enough to run a coffee machine, will enable Statkraft to test and develop the technology needed to drive down production costs.
It's nearly Thanksgiving, the second of the "big" holidays that break up the last three months of the year. One of the most common family traditions is listing the things for which we are thankful. These are mostly items such as "family," "friends" or "good
Last week, the Environmental Protection Agency announced its new green homes Web site. The site provides an interactive experience that helps people
This week, John discussed buying clean electricity from your utility. If you can't set up a small renewable energy system of your own, buying clean electricity is a great way to support the use of renewable energy.
The exterior skin of NREL's newest building will do more than keep the weather out. The concrete panels actually will be part of the Research Support Facilities' heating and cooling system. It's an old idea brought back to life in the name of energy efficiency.
Driving hydrogen fueled SUVs for 431 miles per fill-up is no longer a California dream. Researchers from NREL and Toyota recently completed a 331 mile round trip drive between Torrance and San Diego in two Toyota Highlander Fuel Cell Hybrid Vehicles. And, with the fuel remaining, those...
