Solar is also just as much about storage as it is efficiency. But whatever, not relevant.
The problem with wind is obvious - space. The birds are a semi-issue, but honestly, there are a ton of things besides windmills that contribute to bird deaths in the air, and rarely are birds threatened so much by the turbines as they are by the amount of their habitat that a wind farm takes up.
The problem with coal is clear, but it's so big that it's impossible to actually divest completely. Divesting partially, and investing in partial alternatives, even natural gas if necessary, is a more reasonable option that private businesses would be wise to start doing because of the prices of natural gas versus coal anyway. The problem there is that many cities and townships force a certain energy group on consumers, not that consumers aren't wise enough to figure that part out themselves.
Solar is definitely an option if we get creative - rooftop panels, in particular, would have to become a cheaper option. That said, it's probably going to be awhile before our in-debt-over-their-heads plutocracy actually comes up with a) the funding for solar expansion, and b) subsidies in order to make it a more accessible option.
Hydroelectric and geothermal are excellent for a place like Seattle or San Diego, but not Indianapolis or Detroit in your case, krellin. That needs to be figured out on a smaller, individual city scale if it's ever going to get bigger.
