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."

Historically, wind power has had limited success because continuous winds aren't guaranteed. ... Politicians demanding wind- and water-generated power would yell bloody murder if we had to endure the kind of blackouts Uganda has. Those "alternate" power sources will never do because they are too unreliable and have too many other disadvantages.

While an initial assessment in Ghana, reveals more than 2,000 MW of wind energy potential, mainly along the border with Togo, in Africa, this is quite a significant amount, as by some estimates, the continent needs just 40,000 MW of electricity to power its industrialization (see UNEP Governing Council Report). We should also have an ambitious wind approach on the Keta coastline with a proven potential of over 2000MW. We will link this system to our gas powered generators and create a system where gas powered generation is reduced when there is enough wind power and goes up and vice versa. This way we eliminate the problem of having only wind power when there is wind energy since gas will step in to make up for the shortfall, whiles at the same time cutting down on our thermal energy bills. Spain has done it and to give credence to my claim I list the following existing wind energy capacity for major companies in Spain : Gamesa Eólica, 3281 MW; Made, 803 MW; Neg Micon, 715 MW; Ecotécnia, 446 MW etc. (Source Spanish Energy Ministry).

Abundant, reliable, affordable electricity is thus a critical priority for developing nations. Hydroelectric projects offer one solution, coal-fired power plants another. They aren't perfect ecologically, but neither are wind turbines, which require extensive acreage, kill birds, and provide inadequate amounts of intermittent, expensive electricity that cannot possibly sustain modern societies. Now a revolutionary nuclear energy technology is being designed and built in South Africa, but with suppliers and partners in many other nations. The 165-megawatt Pebble Bed Modular Reactors are small and inexpensive enough to provide electrical power for emerging economies, individual cities or large industrial complexes. However, multiple units can be connected and operated from one control room, to meet the needs of large or growing communities.

Abundant, reliable, affordable electricity is a critical priority for developing nations. Hydroelectric projects like Bujagali (Uganda), Narmada (India) and Three Gorges (China) offer one solution; coal-fired power plants another. They aren't perfect ecologically, but neither are wind turbines, which require extensive acreage, kill birds, and provide inadequate amounts of intermittent, expensive electricity that cannot possibly sustain modern societies.
