America and Germany Getting Their Clean Energy Just Desserts
Germany is the unquestioned world leader in renewable energy. By mid-2011, the European nation generated over 20 percent of its electricity from wind and solar power alone, and had created over 400,000 jobs in the industry. The sweet German success is no accident, however, and the following pie chart illustrates the results of a carefully […]

America’s energy future: iPads vs. typewriters with guns
This post originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. As Americans transition their electricity system to the 21st century, they should ask this question: Does it make sense to pursue strategies such as accelerating the development of new high-voltage power lines that reinforce an outdated […]

Feed-in tariffs responsible for most renewable energy
Cross-posted from CleanTechnica. Feed-in tariffs are a comprehensive renewable energy policy responsible for 64 percent of the world’s wind power and almost 90 percent of the world’s solar power (see charts below). With simplified grid connections, long-term contracts, and attractive prices for development, that’s policy that works. Image: David Jacobs Image: David Jacobs The basic […]

California study is NOT about technological limits. Why glass is 100% full
A recent state sponsored study shows that California could reduce its greenhouse gas emissions 60% compared to 1990 by 2050 with today’s technology(pdf). That has sparked a debate. The glass-half-full crowd, among whom I usually count myself would argue that if we have the technology today to achieve a 60% reduction, if we start implementing […]

California pushes back against energy imports
This post originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. Western grid operators have been making plans for large-scale renewable energy imports into the California electricity market, prompting the governor’s senior advisor for renewable energy facilities to write a “self-reliance” response. Here are a few highlights […]

‘Going Boulder’ means voting for local energy self-reliance
Photo: Zane Selvans This post originally appeared on Energy Self-Reliant States, a resource of the Institute for Local Self-Reliance’s New Rules Project. By a razor-thin margin, Boulder, Colo., citizens gave the city a victory for energy self-reliance on Tuesday, approving two ballot measures to let the city form a municipal utility. If the city moves […]

Don’t let Solyndra fool you: Solar PV is on fire
This post was written by J. Matthew Roney, research associate for the Earth Policy Institute. Additional resources at www.earth-policy.org. Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts (MW) of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 MW of […]
