Ironically, the US is in danger of power blackouts at a time when it is exporting greater and greater amount of coal to China and other countries.
Unfortunately, environmentalists in Texas who blocked the construction of coal-powered plants and shut down others during the last decade did not consider these consequences. All that they thought of was that coal is "dirty," so coal must go. They did not consider what would take its place. Had the coal generating facilities that were planned a decade ago by Texas Power been in place, the rolling blackouts of 2011 might well have been avoided.
Already, America is sending 80 million tons of coal overseas, but plans are underway to increase exports by 10% in 2011.
