The power grid will add a record amount of solar energy as coal plants idle in response to cheap gas and tighter environmental regulations, according to a report from Bloomberg New Energy Finance released Thursday. As a result of the shift, emissions blamed for global warming from power generation will fall 15 percent below 2005 levels.

Developers will install 9.1 gigawatts of solar panels and 8.9 gigawatts of wind turbines this year, helping to replace the 23 gigawatts from coal plants that are expected to close. The rest will come from gas, which power producers will burn at a record rate.
