129 Ethanol studies are all over the map in terms of net greenhouse gas (GHG) benefits or penalties, hinging notably on whether or not “coproducts” are included in the accounting. When these factors are considered, the GHG benefits of corn ethanol over petroleum become negligible, about a 13% reduction when the benefits of coproducts are included. But ethanol produced from cellulosic material (switchgrass) reduces both GHGs and petroleum inputs substantially. A. E. Farrell et al, “Ethanol Can Contribute to Energy and Environmental Goals, Science 311 (2006): 506-508.

136 The ecological footprint is a measure of environmental impact converted to units of land area. Holden and Høyer calculate ecological footprints of four different energy regimes and found that hydropower reduces ecological footprint by -75%, natural gas by -45% to -75% (highest for fuel cells), and oil by -15% to -30%, but cellulosic (wood) biofuel by 0% to +50%.

The Chernobyl Forum is an initiative of the IAEA, in cooperation with the WHO, UNDP, FAO, UNEP, UN-OCHA, UNSCEAR, the World Bank, and the governments of Belarus, the Russian Federation, and Ukraine. The mortality figures in this report are decried by some as being too low, but this comprehensive UN-led effort does represent a conservative assessment of the disaster.

149 Global electricity production from nuclear power was 2,771 TWh/yr in 2005, capturing 15% market share. By 2050, based on a range of global decision scenarios modeled by the International Energy Agency, it could fall as low as 3,884 TWh/yr and 8% market share (“Baseline 2050” scenario, with few new reactors built) or rise to as much as 15,877 TWh/yr and 38% market share (“BLUE HiNUC” scenario, with maximum expansion of nuclear power).

150 Geothermal, ocean waves, and tidal energy are all carbon-free energy sources with high potential in certain places on Earth. However, none is foreseen as becoming more than a niche energy source by the year 2050.
151 Hydropower currently supplies about 2,922 TWh/yr, capturing 16% of the world electricity market. Based on a range of global decision scenarios modeled by the International Energy Agency, it will grow so slowly that it will actually lose market share, rising to between 4,590 TWh/yr and 9% market share (“Baseline 2050” scenario) to 5,505 TWh/yr and 13% market share by 2050 (“BLUE hiOil&Gas” scenario).

153 As of 2006, Germany, the United States, and Spain were leading the world in wind power with 22,247, 16,818, and 15,145 megawatts installed capacity, respectively. India and China had 8,000 and 6,050 megawatts, respectively. The United States is now installing more turbines per year than any other country.

54 Technological advances, increased manufacturing capacity, and bigger turbines have helped to lower the cost of wind energy at least fourfold since the 1980s. Efficiency has steadily increased and the turbines themselves have become larger and taller, with mass-produced rotors growing from less than 20 meters in 1985 to >100 meters today, roughly the length of an American football field. While not yet price-competitive with coal or gas-fired power plants, wind-powered electricity is getting close.
155 Based on a range of global decision scenarios modeled by the International Energy Agency, global electricity production from wind power will rise from 111 TWh/yr and 1% market share in 2005 to at least 1,208 TWh/yr and 2% market share by 2050 (“Baseline 2050” scenario, with no new incentives), and could rise as high as 6,743 TWh/yr and 17% market share (“BLUE noCCS” scenario, with aggressive incentives and no established carbon sequestration technology).

168 Based on a range of global decision scenarios modeled by the International Energy Agency, global solar electricity production will rise from 3 TWh/yr (virtually zero market share) in 2005 to 167 TWh/yr (still virtually zero market share) in 2050 (“Baseline 2050” scenario, with no new incentives), to as high as 5,297 TWh/yr and 13% market share by 2050 (“BLUE noCCS” scenario, with aggressive incentives and no established carbon sequestration technology). Table 2.5, Energy Technology Perspectives 2008: Scenarios and Strategies to 2050 (OECD/International Energy Agency, 2008), 643 pp.
169 Today, some 82% of the world’s electricity is made from nonrenewable coal (40%), natural gas (20%), uranium (15%), and oil (7%). Hydropower and all other renewables combined provide just 18%. Depending on our choices, they could rise to capture as much as 64% market share by 2050 (in an extremely aggressive scenario) or drop slightly to 15%. The true outcome will likely lie somewhere in between these IEA model simulations, but under no imaginable scenario will we free ourselves from fossil hydrocarbon energy in the next forty years.
