Relative / comparative costs of wind energy, nuclear energy, hydro power, coal power, natural gas, geothermal energy, and biomass

By Doitproperly

California Energy Commission reports give costs for power generation from different sources:

David Millborrow’s  ( an ex CEGB engineer Central Electricity Generating Board) ) paper on wind costs gives comparative costs ( This link takes you to the file library – look for…….. David Millborrows paper on wind costs » 157.1 KiB – 1,786 hits – 28 March 2009

It is claimed that inherently renewables are on a decreasing cost curve, while non-renewables are on an increasing cost curve.

AN EU ENERGY SECURITY AND SOLIDARITY ACTION PLAN -gives a detailed cost breakdown of many technologies.

 Energy Sources, Production Costs and Performance of Technologies

for Power Generation, Heating and Transport -

A paper by Professor David Elliot give various cost comparisoin summaries. For space reasons the paper is in two sections, the cost data is tin the second link ( Relative costs of renewable energy and other power generation)   and ( relative costs of power generation and other generation 2) in the Claverton Library, section Energy Data and Statistics

In general it can be seen that there is not a lot to choose between the cost of wind energy, and coal, gas or nuclear.

PV and CSP are considerably more expensive however.

  1. I wonder about the data supporting those figures. Since we can produce electricity for about $.06 kW with $50 per ton biomass fuel, it seems that others ought to be able to do the same or better.

    Of course this figure includes capital, operating expenses, maintenance, labor, etc, etc.

    Thanks for a nice post. For an alternative energy fan like I am this is a great story.

    Thanks for informative info. Hows the political/geographic could impact the base cost?

    Nanosolar is now building 16.4% efficient PV’s at a cost of $0.97/watt for panels that will last >25 years. Given that most places in the US have 40%+ sunny days, mulitply by five (to include nighttime), do the math, and you get $.023/kwh. Two cents, not forty(!)
