Duke Energy says it has reduced carbon emissions by 31% since 2005 and is working toward a 40% reduction by 2030.

Indiana Department of Environmental Management sent letters to utilities in December noting that it can't give approval until utilities show how the plans will control contamination.

The state is considering three routes to relocate the power lines - two of which are along state-owned property.

Duke estimates that by 2020, customers will save an average of about $7, or 5.6 percent, on their average monthly electric bill.

Indiana's largest electric utility company credits the 2017 GOP tax overhaul for what it estimates will be about $7.33 savings per month for the average customer using 1,000 kilowatt-hours a month.

Indiana's largest electric utility says the cut is related to federal tax changes, which reduced taxes for many investor-owned utilities.

Wildlife specialists, Duke Energy workers and volunteers are building a 15-foot-tall tower in southern Indiana to reintroduce injured bald eagles to the wild.

A circuit court ruled that Duke violated its contract with Benton County Wind Farm and has to pay $29 million in damages.

If approved, the solar farm and battery storage equipment would become the first so-called "microgrid" at any National Guard facility in the state.

Duke Energy says the move is an attempt to use "fear and the courts to upend public policy."
