I will offer an opinion on a different direction.
First, there should be no government/tax incentives AT ALL. None for anybody. Not for renewable energy. Not for petroleum or any fossil fuels. Find the true cost, and let the market dictate which solution is best. There should be no regulation mandating what has to be used. Whatever the most efficient and cost effective method is for your area should be the reason you use that form of energy.
Second, I will address the 800 pound gorilla in the room; Nuclear Energy. That is the cheapest, most efficient, cleanest, and takes the smallest environmental footprint of anything we have. The waste issue can be solved safely. It is ignored because of politics, and that is a foolish mistake.
On the surface, nuclear power seem the best bet until you look what goes on behind all this concrete.
The problem with nuclear energy is it's waste. Each plant creates 2,000 metric tons of radioactive waste a year, the waste ends up sitting on site because there is nowhere else to put it according to the DoE. "When we remove fuel from the core after its final usage, we store it in a pool on site, according to the DoE. So, how much lands and waterways do we need to contaminate for this clean power
Then we have the problem such Three Mile Island accident which was a multi layer failure, all nuclear power plants are built on the shores of lakes, rivers, and oceans. Take Washington State famed Hanford Site along the shores of the mighty Columbia River, it's been shut down for years and it was part of a super fund cleanup, all of it's waste is still there buried in multiple safety layers and it's still leaching out. Hanford has onsite 53 million gallons, 25 million cubic feet of solid radioactive waste, nuclear power plants are not clean energy when you take in to account it's waste.
Then we have earthquakes with Fukushima style incident.
