Interesting article in today's NYT about natural gas, and it mentions "Chesapeake Energy of Oklahoma City." Huh?!
New techniques for extracting natural gas have increased estimated world reserves by a MINIMUM of 50%, and some claim that over 600 years' worth of US consumption could be out there. This is nice for many reasons, including freeing the EU from dependence on Russia, who in the past have frozen out parts of Europe by cutting off supplies of natural gas during the winter, but also because natural gas emits less carbon dioxide than most fossil fuels. The combustion of natural gas emits almost 30 percent less carbon dioxide than oil, and just under 45 percent less carbon dioxide than coal. Also, the US has considerable shale reserves, as shown on the map about halfway down this page. It's tough to predict where our future energy will come from, but this seems a pretty promising candidate!
