Wind and Hot Air

Wind turbines generate very little electricity when the air is hot, which is in the afternoon when electricity is needed for air conditioning. Wind turbines work best at night when demand for electricity is very low.

Wind turbines are unreliable because they stop generating electricity when the wind stops blowing.

Wind generated electricity is also very expensive.

Let’s see:

Unreliable, very expensive and generates electricity when it’s not needed.

Obviously this is the perfect place for the government to spend our tax dollars.

Wind energy around the world has been a train wreck.

Spain’s economy shattered, by spending too much on wind.

In England the grid operator pays wind farms to stop generating electricity at night because it destabilizes the grid.

Denmark spent $6 billion on wind energy it didn’t need, since existing generation produced all the electricity needed in Denmark; a country of only 5.5 million people.

Closer to home in Texas the grid came within minutes of shutting down and causing a blackout because the wind stopped blowing.

The economics of wind are bad and will remain so because wind has a low, 30% capacity factor.

Capacity factor measures the amount of electricity actually produced over the period of a year, compared with what could theoretically have been produced based on the nameplate rating of the unit.

A 1 MW unit with a capacity factor of 30% delivers one third the electricity that a 1 MW unit with a capacity factor of 90% would produce. It will take three of the units having a capacity factor of 30% to replace one unit with a capacity factor of 90%.

For this reason it would take 2,000 wind turbines rated 1.5 MW (the standard size at this time) to replace one nuclear reactor rated 1,000 MW (about the average size of existing reactors).

Because the best wind is located some distance from existing load centers, it’s often necessary to build dedicated, expensive transmission lines to carry the electricity generated by wind farms. A study sponsored by the U.S. National Renewable Energy Laboratory estimated it would cost $93 billion to build the transmission lines needed to allow wind to generate only 20% of the electricity in the United States.

Because wind is unreliable it’s necessary to keep gas turbines running so they can be quickly brought on line when the wind stops blowing.

Proponents of wind ignore these costs (transmission lines and gas turbines) when estimating the cost of wind generated electricity.

The billions the government is spending unnecessarily on wind energy could be used to lower our debt.

Because of the hot air produced in Washington DC, wind is the perfect boondoggle: It’s unreliable, very expensive and generates electricity when it’s not needed.
