The Answer, My Friend is NOT Blowing in the Wind

Many states and the Federal Government are putting a lot of faith in renewable energy sources especially wind and solar as solutions for our energy independence and future cost reduction. However, unlike other energy sources such as natural gas, oil, coal, nuclear, tidal, geothermal and to a large degree hydro, wind and solar are much less reliable and cost effective, requiring heavy subsidization. See how Shell Oil just announced today it is backing off its wind and solar efforts as they found them to be not cost effective. 

In fact of the primary energy sources, wind power is the most expensive:
Wind = 21.97 cents per kwh
Gas and oil = 12.28 cents per kwh
Nuclear = 11.06 cents per kwh
Hydro = 7.60 cents per kwh

Believing in wind is a fool's errand. The reasons are simple. Wind is costly, inefficient and erratic.

The New Hampshire Climate Action plan to be released on March 27th by Governor Lynch like the one in neighbor state Maine relies heavily on wind power. Dr. Fred Ward using the NHDES's own calculations, found you could put a wind power turbine on every hill in the state and yet get at most half the electricity that one single nuclear power plant could deliver.

Vaclac Klaus from the Czech Republic in his book "Blue Planet in Green Shackles" asked the question "Could the Czech Republic replace the power output from the Temelin nuclear power plant by wind?" Using conservative estimates the answer is yes but it would take 7,750 wind turbine power plants requiring 8.6 million tons of material and would cover a 413 mile long line of turbines 492 feet high, corresponding to a distance from Temelin in the southern Czech Republic to Brussels in Belgium or in the US, the distance from Concord, NH to Washington DC.

Even if, under ideal conditions, wind could provide a substantial portion of the energy needed for a state or region, you would have to have a back-up permanent and reliable source to turn to when the wind fails. See examples of how the wind has stopped when needed most here, here and here. In other words, hydro, gas, oil, nuclear, or coal turbines must be available and in ready back-up mode at all times. If the ‘shovel ready' sources are at a much less expensive cost, why waste money on an unreliable source? Ask Arnold how the enviro inspired government programs are working so far in his state, which he proudly announced was leading the nation.

Wind energy can be a ‘supplemental', but is will never be a reliable ‘primary' supply of electricity on a large scale. Solar and wind both may have greater potential regionally, say in the deserts of the southwest, the intermountain and the high western plains, but that generated energy must be carried to the national grid and the transmission lines often meet resistance from the same environmental groups pushing the wind and solar as the solutions. Also wind turbines kill birds and bats in large number, upsetting other environmental groups.

There is just nothing we can do to ensure the wind will blow or sun will shine. The governors, state legislature even congress and the administration can?t mandate the wind blow and sun shine, like they can and do control virtually every other aspect of our lives. They brush this off with talk of a smart grid, but while that is necessary, energy storage is just as important, and that has gotten little attention.

To summarize, wind power has half a dozen major problems: erratic behavior, system load problems, dependency problems, need to transmit the energy usually long distances from remote locations, energy must be stored and merged with other sources and the technology requires heavy taxpayer subsidy.

We certainly support conservation and energy innovation but we believe all sources of energy must be pursued including (as Obama called for during his campaign in coal states) clean coal, drilling for oil and gas offshore near the Gulf and in ANWR, extracting oil from tar sands and oil shale, a second generation nuclear, geothermal, tidal, solar and wind. If we don't let the environmental lobby control our future using a failed theory to focus all attention on the carbon dioxide boogeyman and restricting our choices for future energy sources, we CAN be energy independent and have the future we all envisioned possible not too many months ago.  Read more and see calculations here.

ICECAP, International Climate and Environmental Change Assessment Project, is the portal to all things climate for elected officials and staffers, journalists, scientists, educators and the public. It provides access to a new and growing global society of respected scientists and journalists that are not deniers that our climate is dynamic (the only constant in nature is change) and that man plays a role in climate change through urbanization, land use changes and the introduction of greenhouse gases and aerosols, but who also believe that natural cycles such as those in the sun and oceans are also important contributors to the global changes in our climate and weather. We worry the sole focus on greenhouse gases and the unwise reliance on imperfect climate models while ignoring real data may leave civilization unprepared for a sudden climate shift that history tells us will occur again, very possibly soon.
