Top 10 Most-read Blogs of 2011

Here at, we encourage you to lend your voice to the discussion. One of the best methods to do this is to post a blog, and we see fantastic insights each day. In case you missed them, here are the top 10 most-read blogs of 2011 — keep blogging!

Swedish Skeptics Confirm "Nuclear Process" in Tiny 4.7 kW Reactor: I spend much of my time debunking the free energy fantasies of my less technically competent friends. Wishful thinking makes many believe that cars can run on water after seeing a brief youtube video. Lately, however, I have been undergoing an exciting paradigm shift.

Low Energy Nuclear Reactions: 2.5 Million Watt-hours from a Nickel?: All existing nuclear plants, and the planned $13 billion ITER hot fusion project, are based on the "atoms for peace" idea of adapting military bomb technology to civilian use. The tens of billions in research dollars that have been spent have clouded the judgment of leaders in the nuclear science community causing irrational denial of the work being done at low energy levels.

Is the Bloom Box Cheaper Than Solar?: The Bloom Box provides a plug-and-play approach to on-site electricity, using natural gas-powered fuel cells to provide stable, on-demand power.  While it competes favorably with solar PV, its cost is competitive in just a few states with high electricity prices.

Busting 4 Myths About Solar PV vs. Concentrating Solar Power: Although both produce electricity from the sun, there are significant differences between solar photovoltaics (PV) and concentrating solar thermal electricity generation. This guide answers the most pressing questions about the two solar technologies.

Really Cheap, Really Clean Electricity from Boron: This is going to be an exciting winter. Two different revolutionary green energy solutions are about to take giant steps. After 60 years of dangerous nuclear power based on bomb technology, we may finally see nuclear energy that is clean, safe and cheap as dirt. If we could achieve 100% efficiency, E=MC² tells us that one ounce of matter could be converted to seventy million dollars worth of electricity! 


Home Solar PV Cheaper Than Concentrating Solar Power: A residential rooftop solar PV system in Los Angeles, CA, has a cheaper cost per kilowatt-hour of electricity delivered than the most cost effective, utility-scale concentrating solar power plant. In 2010, a buying group called Open Neighborhoods openly advertised an opportunity to get a solar PV system installed for $4.78 per Watt (not including any tax credits, rebates, or grants), a system that would produce approximately 1,492 kilowatt-hours (kWh) per year (AC) for each kilowatt of capacity (DC). 

When is the Renewable Crossover?: As much as some people look forward to the Rapture, people in the renewable energy space look forward to “the crossover.” The crossover is the point in time where the costs of solar energy fall below the price of fossil fuels. The importance of this point can't be over-estimated, because costs will keep falling after that point.

Energy Solutions So Good Even Climate Skeptics Can’t Say No: For all the exciting innovation in clean tech today, debate about energy and climate policies crucial to the market remain stuck in eat-your-vegetables mode. What’s interesting is how some people keep saying no, even as they grab a second helping of spinach.

Clever Accounting Lets Utilities Cash In When You Go Solar: I recently got a copy of a utility bill for a Minnesota business that has a 40 kilowatt (kW) solar PV array.  I wanted to learn how quickly he’d pay off his array with the electricity savings. I was shocked.

Grid Parity for Solar PV with Balance of System Cost Reductions: Cutting non-module solar PV costs with best design practices could make solar PV cost less than grid electricity for more than 25 percent of Americans. Half of the installed cost of a solar PV array is the solar module, but the other half (the "balance of system") involves labor, assembly, and other components.

Hypocrisy? While Buffett Champions Renewables, His Company Fights Rooftop Solar

Mark Chediak, Noah Buhayar and Margaret Newkirk, Bloomberg Warren Buffett highlights how his Berkshire Hathaway Inc. utilities make massive investments in renewable energy. Meanwhile, in Nevada, the company is fighting a plan that would encourage more residents to use green power.
Japan Microgrid

Born from Disaster: Japan Establishes First Microgrid Community

Junko Movellan, Correspondent Although Japan's Fukushima prefecture is most commonly associated with the 2011 disaster due to the nuclear power melt-down, Miyazaki prefecture, located north of Fukushima, suffered from the largest death toll, close to 10...
