Earlier this week, Lawrence Berkeley Labs released a marvelous comparison of residential PV costs in Germany and the United States, finally putting some detail to an enormous gulf in costs (nearly $3.00 per Watt). The following chart (from page 35 of the presentation) shows the cost difference broken down into 9 categories, with ILSR’s addition of … Read More
A story in the Minneapolis Star Tribune today highlights the increasingly common use of 100 meter wind turbines for new wind power projects, up from the previous 80 meter standard. The technological change grabs more wind energy, with consistently higher wind speeds at higher altitudes, meaning states can get even more power from a similar number … Read More
Update 12/20/12: This project includes battery storage. Just last month, the Wright-Hennepin Cooperative Electric Association, serving communities just north and west of the Twin Cities metropolitan area, announced Minnesota’s first community solar project. The 40 kW solar array will be located at the cooperative’s headquarters, with members allowed to purchase individual panels in the project for … Read More
Colorado just launched their long-awaited community solar gardens law (program subscribed in 30 minutes) and California is progressing on a virtual net metering law that could remove one of many roadblocks to community solar. But the Vashon Community Solar Project in Washington State shows that doing solar community-style hasn’t become easy. The Vashon project will be … Read More
Does a Riverside County, CA, residential energy financing program put thousands of homeowners on a collision course with the Federal Housing Finance Agency (FHFA)? In a proposed rule-making, the FHFA has suggested that Property Assessed Clean Energy (PACE) policies represent a threat to the safety and soundness of mortgages held by government-backed Fannie Mae and Freddie Mac. … Read More
This presentation by ILSR Senior Researcher John Farrell explains how – despite solar power that is cheaper than grid electricity – Hawaii homes and businesses still encounter barriers to going solar. You can also download the full report in PDF, for Kindle, or for your Apple iDevice and sign up for updates on ILSR’s energy work. … Read More
When you subtract out shady roofs, renters, and other factors, only about 25% of Americans have a place to install solar power. With the high upfront cost of a complete system, the potential solar universe shrinks further. That changes with “community solar.” After a long wait on the state’s Public Utilities Commission to finalize the rules, … Read More
Many people expect that solar power will dramatically expand once it bursts through the cost barrier and becomes less expensive than grid electricity. But archaic utility rules can effectively cap local solar development at just 15% of peak demand. Fortunately, pioneering states like Hawaii and California are exploring ways to lift the cap and bring utility … Read More
It’s a case study of solar in Ithaca, NY, but it provides a good framework for comparing leasing to ownership in any place in the U.S. Solar Economics in Ithaca, NY Comparing solar ownership to a solar lease can be tricky. The following analysis examines the value of owning a 5 kW solar PV system which … Read More
