ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.

I’ve Done The Math – Now I’m Doing Something About It

Creative Greenius

Bill McKibben’s “Do The Math” article in 2012′s Rolling Stone magazine taught us that we cannot burn any more than 565 gigatons of carbon if we want to stay at 2° or lower. But our friends in the oil, coal and gas industry have 5,795 gigatons of carbon on the books. 15 years.
