A major energy bill has been unveiled by North Carolina House Republicans. It would direct several low-efficiency coal-fired power plants operated by Duke Energy’s North Carolina subsidiaries to transition to alternate fuels by the end of 2030. And a renewable energy procurement program made law in 2017 would be retooled and expanded. Tuesday's bill says the legislation would contribute to a 61% reduction in carbon-based emissions in the state by 2030 when compared to 2005. This compares to the 70% reduction sought by Democratic Gov. Roy Cooper. The bill was drawn up with input from utilities, customer groups and renewable energy boosters.
