There is "Clean Coal" technology, Wind, Solar, Nuclear, Hydrogen powered cars, electric cars, etc.... All of these would be viable alternatives but still could not totally replace fossil fuel. Conservation is the key and it is all of our jobs to do this. I have already parked my Dodge diesel and now drive my Chevy Metro to work. I also burn wood and coal for heat ( like most others here)
I am also ging one step further and putting in a micro hydro turbine in the creek on my property. I will be able to make all the electrical power my home needs and then some. I will no longer have a electric bill and the maintenance is minimal. This will cost me roughly $5,000 which is about 1/4 of what wind power would cost.
i am mostly doing this because the power company is going to raise our rates in Md. 70% in the next 4 years..
