Renewables fastest-growing energy source, feds say

By 2040, coal, natural gas and renewable energy sources will provide roughly equal shares (28%-29%) of world electricity generation -- a tremendous change from 2012, when coal provided 40% of all power generation, according to a new report.
The report, International Energy Outlook 2016, was released today by the U.S. Energy Information Administration (EIA).
Renewables are now the world's fastest-growing energy source and are expected to increase by 2.6% per year through 2040.
