After years of inaction, Missouri has finally moved forward on an ambitious energy agenda.

It should help consumers use less electricity and save money, spur utilities to produce more renewable power and better control harmful emissions from coal-fired power plants.

Voters last November jumpstarted the push by endorsing the Missouri Clean Energy Initiative, which requires utilities to provide more electricity from renewable energy sources such as wind and solar power.

This month, the Missouri General Assembly followed up by sending a solid energy efficiency bill to Gov. Jay Nixon. He should sign it, and then utilities ought to push ahead with new plans to save energy.

A large number of businesses, utilities and environmental groups supported the legislation.

Utilities want to be able to charge slightly higher rates, in part to cover the costs of programs designed to promote energy efficiency.

Consumers benefit with more access, for example, to programmable thermostats or to rebates on more efficient air conditioners.

The new bill recognizes that utilities have few incentives to offer energy-efficiency programs if they simply cut into revenues and profits. That’s where the slightly higher rates would come in, after a thorough review by the Missouri Public Service Commission.

Ultimately, utilities and consumers win if there’s less need to build big, costly power plants, especially those that use coal and harm the environment. As David Warm, executive director of the Mid-America Regional Council, put it, “Every megawatt of energy saved through efficiency is a megawatt utilities don’t have to produce, resulting in fewer emissions.”

Meanwhile, utilities need to also move ahead in following up the good decision by voters last November to back the Missouri Clean Energy Initiative.

The goal for utilities is to use renewable power to produce up to 15 percent of the state’s needs by 2021; the current figure is less than a measly 1 percent. The plan will help trim the state’s use of dirty coal. For that to happen, utilities such as Kansas City Power & Light — which backed the initiative — must fulfill a commitment to build more wind energy farms.

Missouri is embarking on more wisely using energy in the future. The results should be long-term savings on electricity bills and cleaner air throughout the state.
