Wind Farm Turbines Wear Sooner Than Expected, Says Study

By ,- Re-Blogged From The Telegraph

Britain’s wind farms are wearing out far more rapidly than previously thought, making them more expensive as a result, according to an authoritative new study.

The analysis of almost 3,000 onshore wind turbines — the biggest study of its kind —warns that they will continue to generate electricity effectively for just 12 to 15 years.

The wind energy industry and the Government base all their calculations on turbines enjoying a lifespan of 20 to 25 years.

The study estimates that routine wear and tear will more than double the cost of electricity being produced by wind farms in the next decade.

Wind farms are the ‘new apex predators’: Blades kill off 75% of buzzards, hawks and kites that live nearby, study shows

  • Predatory bird numbers are four times higher in areas away from win turbines
  • This is having a devastating ‘ripple effect’ across the food chain
  • It means numbers of certain small animals are growing unchecked

Windfarms Paid Double the Market Price to Cut Power

By Jillian Ambrose – Re-Blogged From The Telegraph

The grid operator is now taking action to avoid future wind power waste.

Wind farms were paid more than double the market price to stop generating electricity this week, despite the country facing an increased risk of blackouts this winter.

Strong wind conditions in the early hours of Monday and Tuesday morning threatened to overwhelm the grid with more subsidised power than needed, forcing National Grid to offer lucrative payouts of between £58 and £115 per MWh to turn the turbines off.

Spring arrives early in Britain following mild winter weather

The payouts stand well above the current market rate of around £45/MWh to compensate wind farms for the subsidies they might otherwise have earned.

A Simple Tale About Switching To Renewable Power: Requirements & Consequences

By Don Bogard – Re-Blogged From http://www.WattsUpWithThat.com

The tale below is fictional, but every one of its elements and issues has been or will be experienced somewhere in the process of switching electrical power production from fossil fuels to renewable wind and solar. Hopefully this tale will illustrate in a non-technical way some of these complications and potential issues that can and often will arise. My reference to “city” and “government” and “city fathers” are generic and could apply to different entities and scales.

Visualize a medium-size city with two very functional electrical power plants, each producing 500 Mega-watts of electricity, with one fueled by coal and one by natural gas. (About 2/3 of U.S. power is produced from these two sources.) The government decrees that this city must reduce its CO2 emissions. The city fathers decide to retire their coal-fired plant because it generates more CO2 and replace it with 350, General Electric (G.E.) 1.5 Mega-watt wind towers (total rated capacity 525 M-watt). The entire city celebrates over their good fortune in moving into a modern era of green energy. The mood is jovial.

Stop Wasting Money on Miracles

Let’s imagine for a moment.

A scientist discovers a new insect which can produce a new kind of fiber. But, not just a mere fiber, it comes out as a full sheet of cloth!

Some commercial enthusiasts of the new discovery say that, since there is zero processing cost to take the fiber from rough to thread to cloth sheet, it is a free supply of material. They do acknowledge that setting up a colony of the insects is expensive and the colony covers a broad swath of land.
