In 2008, Michigan enacted the Clean, Renewable, and Efficient Energy Act which mandated that electricity providers must have 10% of their sales be from renewable energy sources. This helped set a standard for the state to push for being more environmentally responsible, and make use of its resources in order to use them more efficiently.  Michigan's biggest producer of renewable energy is wind energy. Most of Michigan's wind farms lie along the shorelines of the Great Lakes, as can be seen in Fig. 1. In total there are 24 wind farms that together produce about 1,600 megawatts of power. Because of this, Michigan is a top 15 state in installed wind capacity and in electricity generated by wind in large part because of how much coast line there is along the state. Most of these wind farms were developed following the Clean, Renewable, and Efficient Energy Act. This bodes well for the future, as the costs of wind energy have so far been below what had been expected. 
According to Consumers Energy, Michigan's major natural gas and electricity provider, Michigan has continued to make progress in using more renewable energy. In 2016, Consumers produced, from generation capacity it owned, 16.7 TWh (6.01 × 1016 Joules) of electricity, of which 1.06 TWh (3.89 × 1015 Joules), or 6.5%, was renewable.  From generation capacity it did not own, Consumers supplied 19.6 TWh of energy, 11.4% of which was renewable.  In 2015, the 10% standard that was set in 2008 was reached. There is now talk of repealing the hard 10% mandate and setting a goal to reach 35% of the state's electric needs by using renewable energy. Setting the standards higher should keep this trend increasing, and we can expect to see more wind farms, solar panels, etc. installed in Michigan in the near future.
