Seems to, some time ago, MI was trying to draw in high tech businesses, seems many of those factories could turn out wind turbines, communications equipment, medical equipment, solar arays, hydrogen engines...etc.I passed through Detroit years ago, I must have been in the industrial area on the highway and passed through some pretty poor areas, I was not impressed, but the skyline was nice, never got downtown.

What I want to address is shingles are short lifed a bunch from 'cooking ' from the bottom. 95% of houses have poor inadequate ventilation.Dump all those turbine vents, bubble vents,gable end vents, even power vents,,,,they all dont work as well as you think and shouldnt be used any more.

The wind doesn't always blow and the sun doesn't always shine so you are required to have gas turbines as back-up.

There are several strategies to protect from untimely freeze events (air turbines, burning hay, taller trellising away from the colder ground-level air, etc), but the most cost efficient are taller trellises and choosing varieties that develop at the correct times to avoid freeze damage and take advantage of our hot weather to ripen. 

We have a lot of wind turbines in my state and they build then over farm fields.

There is a contract in place for 21 workers for a wind turbine project from 2019-2022.

Very few of those still left in use:Unless you meant wind Turbines?

Also a new 1,000 megawatt gas turbine electric power plant starting construction this year which will by itself add 400-500 construction jobs to the economy over the next two years.   

Even Rawlins has a big boom due to the new wind turbines going in. 

@Jim Cummings 6% of the lost capacity came from frozen wind turbines while 80% of the loss of capacity was from problems at gas and coal fired power plants.
