In This State: Leigh Seddon’s 35 years in the solar power biz

Leigh Seddon, you could say, made hay while the sun shone. For 35 years he has been a solar enthusiast, visionary, entrepreneur and consultant – in short, one of Vermont’s chief proponents of harnessing sunshine to create electricity. He has seen solar grow in Vermont from the simple photovoltaic systems installed by off-grid back-to-the-land types

$16 Million For “Off Grid Electric” From SolarCity

“Off Grid Electric” explains that it delivers 50 times more light for less money than the norm in the markets it serves. The people it supplies are often using kerosene lamps to light their homes. Furthermore, it is more than light that these people need. Pre-pay solar energy from Off Grid Electric gives them electricity to charge

Colorado Utility Leads the Way for Community Solar

An electric cooperative on Colorado’s Western Slope was the first utility in the U.S. to give community-owned solar a chance in 2010. Four years and 2.6 megawatts (MW) later, it was a decision that helped revolutionize the way individuals and businesses go solar nationwide. A member-owned cooperative, Holy Cross Energy (HCE) provides electricity to more than 55,000

New study revisits old news: keep fossil fuels in the ground

If Nature publishes it, will people finally listen? That may be what researchers from the University of London are hoping, because the international science journal has published a new study telling us what we’re already supposed to know—that we need to leave most of our fossil fuels in the ground if we want to keep climate change under control. Bill McKibben’s told us
