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.
Germany has installed enough photovoltaics such that coal-fired power plants are beginning to become unprofitable. This is driven by a combination factors, e.g., that coal isn’t asked to provide power at the peak of the day, when both the sun and the price of electricity are at their zenith. Of course, most of us cheer when coal runs into trouble, but issues like this (more…)
If you ever get the chance to meet Irish-born entrepreneur, Philip Brennan, he’ll be quick to tell you, “Depending on who you believe in my family, I’m a fourth or fifth generation entrepreneur. I’ve worked for big corporations for many years and was tired of trying to turn the aircraft carrier in another direction. It is (more…)
Nautricity is a UK company that develops tidal energy technology. Its CoRMaT tidal turbine, a 500kw device in its largest form, will be installed and tested in the Thames River alongside a former Royal Navy sloop called the HQS Wellington (see Clean Technica article).
The CoRMaT turbine is the subject of at least one (more…)
