As much as wind and solar are increasing, natural gas is increasing more. And gas will continue to grow faster than all other energy sources in the United States for some time.
Over the past fifteen years, coal has decreased from over 40% to 27% of our electricity generation and gas has increased from 17% to about 35%. As a result, greenhouse gas emissions in America dropped to a 25-year low two years ago, although they are now rising again with increased economic activity and an ever-increasing number of gas-guzzling SUVs.
