Comments Off on German coal mine set to become "giant battery" for storing renewable energy

A German coal mine is about to become a massive battery for storing electricity from renewable energy sources. The Prosper-Haniel hard coal mine in the state of North-Rhine Westphalia that provided coal power to German industry since it opened in 1974 will soon be turned into a 200-megawatt pumped-storage hydroelectric reservoir. When completed, the nearly 2,000-foot-deep mine that is set to close in 2018 will essentially act as a giant battery that can store enough power for 400,000 homes. That’s a huge backup that’s much needed in one of the most progressive solar nations in the world. This “giant battery” stores energy by continually pumping water between two chambers, an upper and a lower connected via pipes with turbines. During periods of high electricity demand, power is produced by releasing the stored water from the upper chamber through the turbines and into the lower chamber. When demand decreases, pumps refill the upper chamber using the cheaper electricity available from the grid. Plants such as this tend to have a huge efficiency of about 80 percent, while also balancing the load in a larger power system.

Comments Off on The world’s largest private coal mining company declares bankruptcy

King Coal has seen better days. Mines are being closed, miners are facing widespread layoffs and the market price of coal has crashed over the past several years. The War on Coal just claimed one of its most dramatic casualties, Peabody Energy. The largest private coal mining company, Peabody has filed Chapter 11 bankruptcy for most of its American divisions. Although the company will carry on in a reorganized form, this development represents the major shift away from coal that is happening across the globe.

Peak number of coal plants are shutting down in 2015, ushering in a greener era

Comments Off on Peak number of coal plants are shutting down in 2015, ushering in a greener era

In 2014, 39 percent of American electricity  was generated from the burning of coal, down from 52.8 percent from 1997. Though the fuel source has steadily declined from its late 20th century peak due to competition with other energy sources and increased enforcement of environmental safety measures, the coal industry still maintains great economic and political power. However, Big Coal may face its biggest challenge yet as the EPA implements new regulations governing greenhouse gas emissions. As a result, coal plants are shutting down at an impressive rate.

NASA Discovers That a Massive Methane Cloud Over American Southwest was Caused by Coal Mining

Comments Off on NASA Discovers That a Massive Methane Cloud Over American Southwest was Caused by Coal Mining

NASA scientists have confirmed that satellite data shows a methane hot spot in the southwest United States that is so big that it was ignored for years as a possible instrument error. The cloud of methane gas — a short-lived climate pollutant (SLCP) that  is around 30 times more potent as a heat-trapping gas than carbon dioxide — takes up 2,500 square miles above the Four Corners region where Arizona, Colorado, New Mexico, and Utah intersect. The methane plume is about the size of Delaware and released about 0.59 million metric tons of methane into the atmosphere annually during the seven years it was studied from 2003 to 2009.

In what really seems like stating the obvious, or at least stating what has been said many times before, the Environmental Protection Agency has found that water quality downstream from mountaintop coal mining operations in West Virginia and Kentucky is highly toxic. The Charleston Gazette reports…
