    The point is. Renewable energy isnt there yet. Hydro electric is the best we have. If you want to replace a gas or coal fired grid. You cannot do it with 100% renewable energy. The only tech we have that can replace fossil fuel grids is nuclear power. I’m not saying its the only way. I’m saying its the only thing that works at this time unless something happens to radically reduce energy demand and the type of radical reduction required simply isnt gonna happen. As for the profit. Windmills dont make money. They cost money. They are more expensive to maintain than the energy they produce. 2.5-5m USD to build one. They cost 1.3m USD give a few thousand per megawatt of electricity producing capacity. Maintenances costs can range around 45-50k annually. Land costs. Business overhead. Etc. You go thru that to produce 1-3 MW of electricity… Thats not enough to do much of anything. And u cannot suddenly demand a huge spike of energy from a windmill farm like you can from coal or gas or nuclear. Solar same thing. Sun not shining? No power.

    My point overall is these are not good cost effective alternatives to current energy production. They are expensive and inefficient alternatives to what we have. Are they greener? Yes they are but under the current technology. Green energy doesn’t get the job done that HAS to get done.
