Wicked Waste: Why Every New Wind Turbine Built Is Costing You Serious Money

Adding wind turbines to a power grid is like pushing on string; the effort applied rarely matches the output at the other end of the line.

Australia has one the world’s largest interconnected grids, covering Queensland, NSW, ACT, Victoria, Tasmania and South Australia – with wind turbines plastered far and wide across every one of those States (save ACT). And yet, there are numerous occasions when the entire 7,728 MW of wind power capacity connected to that grid is delivering less than 5% of that capacity, and plenty of occasions when its fleet of whirling wonders struggles to produce 2% of its notional capacity: Dead Calm: Australia’s Wind ‘Industry’ Suffering From Prolonged Wind ‘Drought’

Pathetic, costly and pointless.

While ideologues continue to wax lyrical about an all wind and sun powered future, those gifted with logic, reason and a little arithmetic beg to differ. One of them is Donn Dears. Here is spelling it out in clear and simple terms.

It’s Time to Abandon Wind Power

Adding more wind turbines to the grid merely replaces lower cost methods for generating electricity.

Every new wind turbine built this year is totally unnecessary.

The consumption of electricity is forecast to decline in 2020.

Actually the growth rate for electricity consumption for the past ten years has been nearly zero, and this means that virtually every new wind turbine added to the grid since 2010 has been a waste of money.

But it’s worse than that. Every new wind turbine added to the grid has resulted in higher costs for the consumer, because the coal-fired and nuclear power plants displaced by wind turbines produced electricity at a lower cost.

This is the real result of adding wind to the grid.

It’s time to stop adding wind turbines to the grid.

The cost of electricity produced by wind turbines is greater than the cost of producing electricity using natural gas combined cycle (NGCC) power plants.

The EIA is misleading Americans when they say that the levelized cost of electricity (LCOE) from wind is the same as from NGCC power plants.

Even if that were true, which it isn’t, the use of increasingly large amounts of wind requires the use of storage … and storage costs a great deal of money.

There is no way that wind lowers the cost of electricity for Americans. Instead, it increases the cost for every American.

In addition, wind is unreliable. No one can accurately predict when the wind will blow.

Wind turbines don’t generate electricity until the wind is at least 6 mph, and the wind turbine must be shut down when the wind speed is greater than 55 mph.

Not only that, but wind turbines must be shut down when there are severe freezing conditions.

The net result is that wind is unreliable and must have storage to back it up.

Cost is also increased because the best wind for wind turbines is located a thousand miles from where it’s needed, or off shore where bringing it to the grid is expensive. New, very expensive transmission lines must be built to bring the electricity to where it is used.

The cost of unnecessary transmission lines, especially those that are under water, aren’t included in LCOE calculations, but every American must pay for those unnecessary new transmission lines.

Wind turbines are expensive to build. It costs $2,000 per KW to build a new wind turbine, while it only costs $1,000 to build a new NGCC power plant.

The wind turbine will have to be replaced after 20 years, while the NGCC power plant can operate for 60 years.

What’s even worse is that the capacity factor (CF) for on-shore wind has been 30% or less, and with the newer larger units it could be around 35%. But the CF for a NGCC power plant is around 87%.

As a result, the NGCC power plant produces more than twice as much electricity as does a wind turbine over the year.

It’s long past the time since we should have abandoned wind turbines.

They are expensive, unreliable, need costly storage or backup, and generate only small amounts of electricity.
