All our electrical plants are certainly not coal and natural gas. Do you think we build those hydroelectric dams for show? We have power of operational nuclear reactors and in isolated cold weather ares diesel generators are the norm. Not to mention that solar and wind really are being used in real people's houses.
Also millions of homes on the east coast use heating oil or gas for heat, and quite a few are using kerosene as well. So oil is being used in plenty of areas electricity could replace.
And there has never been an electrical shortage? What are you 12? Do you not remember the brownouts and blackouts in California and the northeast less than 10 years ago during the summer heatwave? There are areas were electricity must be conserved during the summer or all the air conditioning units will use up more power than is available and cause power failures.
And if you are so concerned about tax dollars, they go to oil too. There is almost nothing around that doesnt get a government subsidy one way or another.
Solar, hydroelectric, geothermal, wind and nuclear power are being used as alternatives to fossil fuels all over the world you can whine about it. It these technologies prove themselves everyday and I don't see you developing alternatives.
