Wind and solar energies have very unique and punctual applications, and making huge wind and solar farms is not one of them. They are very useful in areas where there is no connection to a power interconnected grid. But they provide little power in return to their investment costs. Solar and wind energies are too diffuse, and on our present industrial and domestic energy demand, we should keep relying on dense energy fuels as nuclear or coal providing constant and reliable baseload power.

Solar and wind energy farms must always be subsidized in order to their owners to have a profit. And that profit comes from taxes (user's money) and from higher kW/h prices that drive up industrial production costs and decrease competitiveness in foreign markets. But the temptation of having "free energy" is too high for gullible followers of the myth of renewable energy. They might as well run and find that pot of gold coins at the end of the rainbow.
