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
Get Solar, August 3, 2012 The Aloha State has many natural resources, including its volcanoes and its miles of shoreline, but one thing the state lacks is an abundant source of fossil fuels. Hawaii had to import 94 percent of its energy sources in 2010, according to the Energy Information Association. However, Hawaii does have an … Read More
Grist, July 31, 2012 Probably the most important energy-related vote this November is happening in the swing state of Michigan, where voters will decide whether to substantially boost the state’s renewable energy standard (RES). It’s a big deal for all sorts of reasons, many of which extend beyond the state itself. So let’s walk through the … Read More
The report finds that while the economics of solar continue to improve, a number of unexpected barriers have arisen. Homes often need electrical upgrades and local governments struggle to keep up with permit requests. Utilities are also reluctant to give up their market dominance, enforcing antiquated rules about grid interconnection that can add significant expense, delay, or even kill projects entirely.… Read More
First in the U.S., Hawaii residents and businesses can install solar power – without incentives – for less than the cost of grid electricity. But as local Earthjustice lawyer Isaac Moriwake notes, “the gates of heaven do not open just because solar is cheap.” Instead, a number of unexpected barriers have kept the solar market from … Read More
Big dreams for renewable energy often goad people into imagining big wind projects, with hundreds of turbines. But lots of smaller projects are just as likely to add up to big numbers. Counting wind projects from 1999-2010 (based on data from LBNL’s excellent Wind Technologies Market report) the average size of an American wind project is … Read More
Big dreams for renewable energy often goad people into imagining big solar projects, with acres of panels. But lots of smaller projects are just as likely to add up to big numbers. Counting solar projects from California and New Jersey (which together make up half the U.S. solar market), the average size of an American solar … Read More
