Wind power is not free. All natural energy resources such as coal, wind and sun appear “free” – no one has to incur costs to create them. But turning a “free” resource into usable electricity costs money for collecting, generating and distributing that energy. To consumers and tax payers, the real cost of wind power is very high, no matter how well it is hidden by politicians.
Wind power is not reliable. No one can make the wind blow when the energy is needed – in fact, wind farms produce, on average, less than 30% of their nameplate capacity, often at times of lower demand.
Wind power harms the environment. Because of the large area of land needed to collect low-density wind energy, wind power requires more land-clearing, needs more transmission lines, kills more wildlife, lights more bushfires and uglifies more landscape per unit of electricity than conventional power. And the subsonic whine of the turbines drives neighbours batty and devalues local properties.
Like hydro-power, wind power is limited, with few suitable sites. And every wind turbine slows the wind, thus reducing the wind energy available to any downwind turbines. It is “renewable’ but it is not unlimited.
Wind power is justified by claims that it reduces emissions and thus reduces global warming. However, when all the steel, concrete, construction, maintenance, replacement and rehabilitation are taken into account, wind power contributes nothing to reducing emissions or changing global climate.
However wind turbines DO change the local weather. Wind is the major component of weather. Winds bring moisture to the inland, clear pollution from the cities, and change air temperatures everywhere. Wind towers rob the wind of its energy, affecting local wind speeds and changing local weather patterns.
Wind power is an expensive, intermittent and limited energy source that degrades the environment, kills birds, affects the local weather but does nothing to improve global climate.
It should be paid for by those who want it, not by captive taxpayers or electricity consumers.
