A state House panel has voted to require that 10 percent of electricity sold to Michigan consumers come from renewable energy sources by the end of 2015.
That standard is nearly triple the current amount of alternative energy sold by utilities and other power producers.
The bill could cost residential customers an extra $36 a year.
More than 25 other states already have renewable energy standards for energy companies, but the issue is far from settled in Michigan.
Senate Republicans oppose a renewable energy standard as a government mandate and instead favor tax credits for people who buy such energy.
Supporters say setting a renewable energy requirement would boost jobs and reduce pollution and dependence on coal.
