I can't believe how fast winter gave way to summer. Seems like just yesterday we were digging out from Snowpocalypse here on the East Coast, dealing with mountains of the white stuff and wondering if we'd ever be out of the deep freeze.
In my quest to learn what other local groups are doing to help the environment and hopefully avoid reinventing the wheel, I attended a meeting of the Greenbelt Climate Action Network, a local chapter of the grassroots, nonprofit organization Chesapeake Climate Action Network. There I met...
Energy captured from the natural flows of tides and rivers, without the use of dams or large civil structures – kinetic hydropower – has begun to emerge as a viable, low-impact clean energy option.
On Monday, John told you about community efforts to save energy. John works with various organizations in his community to promote energy savings, and he has found that none of these organizations can do it alone; many local groups are now partnering with nonprofits, volunteers, community...
The ZigBee Alliance and the SunSpec Alliance today announced an agreement to collaborate on defining standards for renewable energy and microgrid management using the ZigBee Smart Energy version 2.0 standard. The ZigBee Alliance is a global ecosystem of companies creating wireless solutions for use in energy management, commercial and consumer applications...
We hear a lot about renewables like wind and solar these days, but what's the deal with fuel cells and is there a future in them? The truth is, fuel cells have been around for some time now; the idea originated in the 1840's.
Vice President Joe Biden kicked off Earth Day in April by announcing the selection of 25 communities to receive up to $452 million in Recovery Act funding to "ramp-up" energy efficiency building retrofits. Under the Department of Energy (DOE) Retrofit Ramp-Up initiative, communities,...
When the first warm rays of springtime sunshine trigger a burst of new plant growth, it’s almost as if someone flicked a switch to turn on the greenery and unleash a floral profusion of color. Opening a window into this process, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory...
The marketplace for Smart Grid technology products is expanding thanks in part to an open-source communications specification developed by Lawrence Berkeley National Laboratory (Berkeley Lab) and its research partners.
