The latest solar numbers have just come in, and the celebration continues. The latest industry report shows another 4,751 megawatts (MW) went in during 2013, with great progress for both photovoltaics (PV) and concentrating solar power (CSP). Solar in the U.S. now generates enough to power over 2 million average households. Read More

A Map of Every Wind Turbine in the U.S. — Interactive USGS Map Shows Locations of More than 47,000 (and Counting)
March 3rd, 2014
With their tall towers and graceful kinetic ways (read: moving parts), wind turbines aren’t hard to spot if you’re near them. If you want to see the big picture, though, and how your local specimens fit within the national panorama for this exciting technology, a new map tool from the Interior Department’s U.S. Geological Survey makes that easy as pie. Here are the What, Why, and Whee. Read More

More information has come from the authors of a recent wind-turbines-and-property-values study of Massachusetts via a webinar and related Q&A. The answers continue to point to room for additional studies, but reiterate the positive findings: “The results do not support the claim that wind turbines affect nearby home prices.” Read More

A new study looked at how well wind turbines and homes fit together in Massachusetts, and found no evidence that wind turbines affect property values. That finding is consistent with other recent work from a range of states across the country. And it’s good news for everybody wanting to get wind turbines sited responsibly, in the Bay State and beyond. Read More

On January 5, “60 Minutes” included a story on “The Cleantech Crash,” claiming that investors, both private and government, haven’t gotten their money’s worth for all their investments in clean energy technology. As any rational look at the clean energy transition clearly reveals, the show got a few things right, but a whole lot more wrong.

The last 12 months have brought a lot of change to the world — some good, some less so; some too fast, some too slow. But in the energy space, the essential transition to energy that is cleaner, healthier, lower-cost, and more secure is definitely underway in the U.S. This year, we saw strong signals that we’re moving in the right direction on energy, with renewables like wind and solar (going up), coal (going down), renewables integration (looking good), and energy storage (on its way). Here’s a look at some of the year’s highlights. Read More

The day after Thanksgiving around our house this year, as usual, involved cleaning up from the festivities of the day before, harvesting a tree, and stringing the lights. The scrumptious desserts at our celebration on Thursday may have added to my weight (I promise to exercise more, really), and the tree may have involved a little slice of temporary deforestation (though I know the Christmas tree farms plant more).
But thanks to LED technologies, the part about the holiday lights involves a whole lot less electricity — and carbon — than it used to. Read More

If droughts, heat waves, and power plant troubles aren’t strong enough signals that power plant water use is something worth paying attention to, maybe this week’s approval of an energy-water resolution by NARUC, the national association of utility regulators, can help. Understanding the importance of actions like NARUC’s (and Mother Nature’s) depends on understanding how much water U.S. power plants use, and why. It’s a good time to take stock of what we know about that issue. Read More

NARUC may not be a household name, but it, as the national body of state public utility commissioners (PUCs), deals with a whole lot of important issues for consumers in every state. And today its members weighed in on the important issue of power plant water use, following up on what UCS, Mother Nature, and others have been saying about water-related risks for the power sector, and how to deal with them.

The latest ranking of states’ energy efficiency policies and programs is out, and many of the results are what you’d expect. (Hint: the Red Sox aren’t the only winners in this neck of the woods.) But there are some surprising results worth checking out—including shout-outs for Mississippi, Illinois, and others. Read More
