FORUM: Perils of wind and water

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.

Ghana: Energy - Paradigm Shift Advocated

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).

If we want to help the Third World, let's promote nuclear power

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.

Nuclear to the rescue - Electricity is the key to a healthier, more prosperous Third World

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.

Energy Not Quite As Free As the Wind

CAPE Town has, with much fanfare, just embraced wind power, that green panacea of sustainable and clean energy. But we are most unlikely to hear of its cost, its inefficiency and, indeed, its damage to the environment. We will hear that wind power helps curb our greenhouse-gas emissions, makes the country less dependent on fossil fuels and energy imports and -- the icing on the cake -- also creates jobs. Surely this is the solution to many of the world's biggest problems? To see if these alleged benefits actually stand up to closer scrutiny, let us look at a country held up as a shining example: Germany.
