Busting 4 myths about solar PV vs. concentrating solar

Although both produce electricity from the sun, there are significant differences between solar photovoltaics (PV) and concentrating solar thermal electricity generation. This guide provides answers to the most pressing questions about the two solar technologies. 1. Isn’t concentrating solar power cheaper? No. Five years ago, the two technologies were relatively comparable, but in 2011 there’s no doubt that distributed solar PV is cheaper than concentrating solar power.   A concentrating solar power plant has a capital cost of $5.50 per watt without storage, and $7.75 per watt with six hours of thermal storage. The levelized cost of electricity from a Mohave …

Don't Forget the Small Stuff

Distributed renewable generation = big numbers

Distributed renewable energy comes in small bites, but it makes mouthfuls — gigawatts — of renewable energy capacity. Americans tend think big, but it is countries that built small that are hitting big renewable energy targets. Take Germany. In 2009, it installed 3,000 megawatts (MW) of solar PV, more than three times all the solar PV installed in the U.S., ever. Over 80 percent was installed on rooftops.Distributed wind power scales, as well. Of Germany’s 27,000 megawatts of wind power projects (third most in the world and most per capita), nearly 90 percent are smaller than 20 megawatts, with most …

Community wind projects still require financing acrobatics

Wind projects shouldn’t require financial acrobatics.Photo: Chris GawThis is part of a series on distributed renewable energy posted to Grist. It originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. Community wind projects deliver larger economic returns and encounter less local resistance, but a new report released last week shows that developing community wind still requires a daunting effort. The report, by Lawrence Berkeley Labs wind guru Mark Bolinger, illustrates the new heights of financial acrobatics required to finance community wind projects. The history of community wind was already rich with terms like …
