Ridiculously expensive: Wind and Solar Energy

The Economist, a British magazine, discusses a report done in the U.S. that compares the costs of wind and solar energy to coal.

Coal?  Yeah - coal is very cheap.

Wind and Solar are not cheap.  They are ridiculously expensive.

We don't have to pay high energy costs.  This applies to investment costs as well.  PB

From the Economist.com:

Solar power is by far the most expensive way of reducing carbon emissions - it costs $189,000 to replace 1MW per year of power from coal.

Wind is the next most expensive.

Hydro-power provides a modest net benefit.

But the most cost-effective zero-emission technology is nuclear power.

The pattern is similar if 1MW of gas-fired capacity is displaced instead of coal.

And all this assumes a carbon price of $50 a tonne.

Using actual carbon prices (below $10 in Europe) makes solar and wind look even worse.
