Low Benefit -- Huge Negative Impact (part 2)

[From a National Wind Watch flyer of the same name;  click here for part 1]

Why do utilities support them?

Given a choice, most utilities choose to avoid such an unreliable nondispatchable source. In many states, they are required to get a certain percentage of their energy from renewable sources. In other states, they anticipate being required to do so in the near future. These requirements do not require utilities to show any benefit (e.g., in terms of emissions) from using renewables<\m>they just need to have them on line.

In Japan, many utilities limit the amount of wind power that they will accept. In Germany, the grid managers frequently shut down the wind turbines to keep the system stable. In Denmark, most of the energy from wind turbines has to be shunted to pumped hydro facilities in Norway and Sweden.

Yet wind energy is profitable. Taxpayers cover two-thirds to three-fourths of the cost of erecting giant wind turbines. Governments require utilities to buy the energy, even though it does not effectively displace other sources.

In addition, wind companies can sell "renewable energy credits," or "green tags," an invention of Enron. They are thus able to sell the same energy twice.

The companies generally cut the local utilities in on some of the easy profits.

Why do communities support them?

Developers typically target poor communities and make deals with individual landowners and the town boards (which are very often the same people) long before anything is made public.

With the prospect of adding substantially to the tax rolls and/or hundreds of thousands of dollars in payoffs each year, it is understandable that a lot of people are reluctant to consider the negative impacts. They are willing to ignore the effects of such large machines on themselves and their neighbors. Excited by the financial promises of the wind companies, they forget that their giant machines will destroy precisely what makes their community livable.

As people find out more, support for the harmful boondoggle evaporates.
