Wind power is a mature technology, used widely in Europe. In Germany it produces 20 000MW. ...Unfortunately, South Africa is not the best location; there is just not enough wind to generate sufficient sustainable electricity supply. ... To generate large amounts of electricity from wind turbines would require large tracts of land. A wind turbine that generates 5MW could have a 12m diameter. In comparison, an Airbus A380's wingspan is 80m. So to generate a large amount of power, say Koeberg's capacity of 1 800MW, you would need about 380 5MW wind turbines. ...Wind will be a small part of South Africa's future energy mix. Solar power holds more promise as an environmentally friendly solution to South Africa's energy crisis.

Indigenous peoples from the Amazon to Asia said on Wednesday that U.N.-backed clean energy projects meant to combat global warming were aggravating threats to their livelihoods. They said hydropower projects or plantations of fast-growing trees, prompted by a billion-dollar scheme under the U.N.’s Kyoto Protocol for limiting the planet’s dependence on fossil fuels, were damaging nature. “We are not only victims of climate change, we are now victims of the carbon market,” Jocelyn Therese, a spokesman for indigenous peoples of the Amazon basin, told a news conference on the fringes of U.N. talks on global warming. “Efforts that are supposed to…retard climate change are having an equally disastrous effect,” said Ana Pinto, representing indigenous peoples in India.

A World Bank scheme to bring electricity to the world's poor is short-sighted and won't curb climate change or help the people it's aimed at, environmental groups said on Sunday. The Bank released a progress report on Sunday looking at ways to fund cleaner energy projects in some of the world's poorest regions and drive economic growth in those areas. The report, entitled Investment Framework on Clean Energy and Development, says an estimated 1.6 billion people do not have access to electricity. Environmental groups said the Bank was missing a huge opportunity to promote the use of renewable energy by instead backing conventional fossil-fuel based generation.

"Wind power is unfortunately not the holy grail of electricity supply for the future. Despite this energy source, wind, being free, the very high capital investment required and the high maintenance costs result in high generating costs."
