They should do the smart thing! Take the 50-year plan and get out of the business producing power business and transition into a pure distribution mode. The power companies should be encouraging us all to go the solar route where-ever economically and technologically feasible. Let the market dictate the rate, end the subsidies for solar installation, and encourage the sell back electricity. All with the understanding that 50 years from now most coal and gas fired plants will close their doors and we'll get all the "free" power we can collect.
The idea of owning a mini-solar farm on 5 acres of cheap scrub land and driving an electric car doesn't sound so bad!
The 50-year plan will work when resolving many issues. Poverty, unemployment, hand-gun proliferation, drug abuse, urban crime, ineffectual government. It only takes a well reasoned plan and the resolve to see it through.
