Wind Power Is Cheaper Than Coal, Leaked Report Shows
merbs writes: A leaked report shows wind is the cheapest energy source in Europe, beating the presumably dirt-cheap coal and gas by a mile. Conventional wisdom holds that clean energy is more expensive than its fossil-fueled counterparts. Yet cost comparisons show that renewable energy sources are often cheaper than their carbon-heavy competition. The report (PDF) demonstrates that if you were to take into account mining, pollution, and adverse health impacts of coal and gas, wind power would be the cheapest source of energy.
we'll be looking at a full on runaway greenhouse effect such as devastated Venus.
Nope. The Kombayashi-Ingersoll limit says that a Venus-style runaway greenouse is not possible on earth because the sun isn't bright enough unless you brought the albedo down below about 7%.
