So far, CNG vehicles haven't made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles. There are about 1500 CNG refueling stations in the US, which is about the same number of commercial stations offering E85 ethanol blends. Utah has a total of 91 CNG filling stations, most of which are reserved for commercial fleet use, but there are 20 open to the public. According to an article by the Associated Press, you could drive Utah from top to bottom and hit 22 different stations offering compressed natural gas.

WASHINGTON (AP) - An Energy Department report concludes that wind turbines can produce a fifth of the nation's annual electricity needs within about two decades. That is about the same share of electricity produced today by nuclear power. Wind energy today accounts for only about 1 percent of the nation's electricity. The government report to be released Monday said by 2030 wind energy could account for 300,000 megawatts of power, or about 20 percent of the total electricity generated.
