In a victory of David vs Goliath proportions, policymakers in Arizona stood up for its citizens by rejecting an attempt from the state’s largest utility to squash rooftop solar. Five months after Arizona Public Service (APS) sought approval to slap hefty new fees on its customers that go solar, the Arizona Corporation Commission (ACC) voted last week to (more…)
Here’s a Business Week article whose point is that the relevance of our power utilities is disappearing. Not true. Unless there is a breakthrough in energy of unprecedented proportion, along the lines of cold fusion or something else that appears equally unlikely at this point, our electrical utilities will continue to play a critical role in our lives, largely (more…)
One of the U.S.’s largest electric utilities has agreed to close three coal-fired power plants in the Midwest, the latest sign of how the U.S.’s electricity supply is shifting away from coal to natural gas and renewable energy.
American Electric Power (AEP) will shut down the three plants in Indiana, Ohio and Kentucky by 2015 — retiring a total of 2,011 megawatts of coal-burning (more…)
Coal is somewhat notorious for not being the cleanest of fuels. Similarly all combustion systems release a good deal of carbon dioxide. A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale. (more…)
Here’s a video that shows where I spent my afternoon: on a tour of the (currently) 2 megawatt solar photovoltaics facility at Fort Hunter Liggett in Central California, now the largest solar array on a military base in the U.S. – and soon to be a microgrid. As I took a tour with some colleagues, work was underway for Phase Two, which will add two more MW, and enough battery (more…)
Rising water temperatures and a reduction in river flows have caused declining production at some thermoelectric power plants in the U.S. and Europe, a trend that will likely continue for decades to come as the planet warms, according to a new study.
