ANN ARBOR, MI - State Rep. Yousef Rabhi wants to see Michigan step up its game to reduce pollution and address climate change.

The Ann Arbor Democrat introduced a bill this week that would require all of Michigan utilities' energy to come from renewable sources such as wind and solar by 2050. House Bill 6466 would expand on the state's existing renewable portfolio standard, requiring energy providers to meet a series of new targets between 2019 and 2050.

"Strengthening Michigan's commitment to renewable energy is vital to the health of our citizens and our economy," Rabhi said.

"As renewable technology becomes increasingly affordable, we have the opportunity to invest in good jobs in our own state, save consumers money, and protect our air and water."

Currently, only 10 percent of the state's energy must come from renewable sources such as wind and solar. The state's renewable requirement for utilities goes up to 15 percent in 2021.

Rabhi's bill would raise this standard to 25 percent by 2025, 50 percent by 2032, 75 percent by 2040, and 100 percent by 2050.

Rabhi's office notes the United Nations Intergovernmental Panel on Climate Change recently released a report warning that ecosystems and human health are in danger without swift action to limit global warming to 1.5 degrees Celsius.

"On the heels of a major new report finding that, if left unchecked, some of the worst impacts of climate change will hit us sooner than previously believed, it is now more important than ever that we take action to move fully towards renewable energy," Charlotte Jameson, energy policy and legislative affairs director for the Michigan Environmental Council, said in a statement in support of Rabhi's bill.

"Transition to 100 percent clean, renewable energy is achievable and will usher in more economic prosperity for the state while reducing costs for families and protecting public health and the environment."

DTE Energy, which serves roughly 2.2 million customers in southeast Michigan, announced earlier this year plans to double its renewable energy over the next four years with wind and solar projects.

DTE said last year it plans to reduce the company's carbon emissions by 80 percent by 2050 by moving away from burning coal, and have 40 percent of its energy coming from renewable sources by 2040.

DTE's plan includes interim targets of reducing emissions by 30 percent by the early 2020s, by 45 percent by 2030, and by 75 percent by 2040.

That's to be achieved by shuttering aging coal plants and replacing them with a mix of natural gas and renewable sources such as wind and solar. In 2040, DTE's targeted mix of energy is 20 percent nuclear, 40 percent renewable and 40 percent natural gas.

The city of Ann Arbor has a goal of powering 100 percent of the city's municipal government operations with clean and renewable energy sources such as wind and solar by 2035 or sooner.
