Wind power is justified by claims that it reduces carbon dioxide 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.
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. Wind farms produce, on average, less than 30% of their rated 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. Some houses affected like this are abandoned by their owners because they are unsaleable. No-one will buy them.
