Why can't we replace our coal burning and nuclear power plants with renewable energy sources?
For example we have enough wind power in the United States to replace all of the fossil fuel and nuclear power sources in the United States.
Athough wind does not always blow when you need it, it would seem that in a power grid you will always have wind blowing somewhere to put electricity into the grid.
The cost of wind power at 4 cents per kilowatt hour is competitive with the cost of electricity generated by coal and nuclear energy and less than the cost of generating electricity using natural gas.
What is preventing us from replacing our fossil fuel power plants and our nuclear power plants with electricity from renewable non carbon sources?
We can replace coal, and other fossil fuels.
We can't do it without using nuclear right now, at any reasonable cost. The cost you cite may be theoretically possible, but present wind farms can't match that. One problem is that you need a LOT of excess capacity to cope with no wind some places sometimes.
We can build nuclear power plants that are safe and safe from terrorism. We can dispose of the waste safely, it's just a political problem to designate a site.
A reasonable plan is to press ahead on all three fronts; nuclear, solar, and wind. The goal would be to run the nuclear plants for one "lifetime" (30-50 years) and then replace them with improved wind and solar as they wear out.
Your idea is good, but we need nuclear to make the transition away from fossil fuels right now.
