A coalition of business, labor and agriculture groups is backing a ballot campaign to boost the state’s renewable energy mandate.
Michigan utilities are already required to get 10 percent of their energy from renewable sources like solar and wind by 2015. The proposed constitutional amendment would boost that to 25 percent, by 2025.
"There’s 20 other states that include and Illinois, Minnesota and Iowa that have already adopted measures similar to the initiative, without significant increase in utility costs for consumers," said campaign spokesman Mark Fisk.
A spokesman for DTE Energy says it would be difficult to comply with the 25 percent mandate without a significant increase in rates. The proposed ballot language says utilities could not increase rates by more than one percent a year to comply with the mandate.
A state elections board is expected to decide whether to approve the ballot language this week.
