The so-called alternative fuel industry, other than oil, gas and coal, may be preferred by environmentalists, but is unrealistic from a practical point of view.
Wind power is not too bad. It’s cheaper than solar power and it also takes less land. Yet, it still is subsidized and not comparable to what we can get for our immediate needs at low cost, and without taxpayer help
New solar thermal power, which also is not cost-competitive, requires lots of empty land which is not always available. It uses the sun as a means of heating water. That turns turbines. Silicon-coated photovoltaic method is not as good.
The alternative fuel industry we hear so much about is not practical, in so many ways.
