Regardless of whether the climate is gradually getting warmer--which it has, since the Ice Age ended, and very little of that was caused by Europeans. There is still a changing market for electrical appliances and energy production that the United States should take advantage of.

We took advantage of a changing energy market after World War 2, when the rest of the world wanted the power trains and power plants that the US could produce, in heavy vehicles and diesel engines. This is why General Motors soared---not so much American demand, but also worldwide demand for their products. This changed the whole character of the upper Midwest---from a commodities based economy to an industrial one.

Now the demand is for consumer electrical appliances. And because those are more efficient than a generation ago, there is more practicality to smaller scale electric production. We don't necessarily need big dams blocking rivers, and the middle east doesn't really need nuclear plants springing up, built by Russia and China. There are lots of places solar or wind power or micro hydro generation could become a cost effective alternative.
