Renewables roll-out needs price guarantees

Power generation from renewable sources such as wind turbines, solar cells and biomass plays a small but important part in satisfying total electricity demand around the world, and is growing at an exponential rate thanks to generous public subsidies and government support.

Renewable sources have increased their share of worldwide generation from just 0.4 percent in 1980 and 1.1 percent to 2.3 percent in 2006. In its "World Energy Outlook 2008", The International Energy Agency (IEA) projects their share will double to 4.9 percent by 2015, and then almost double again to 8.7 percent by 2030.

Policymakers are relying heavily on renewable generation to meet projected growth in the electricity demand over the next 20 years while limiting growth in the emission of greenhouse gases.

Unlike reserves of oil and gas, which may be exhausted within the next 70 years, renewables will remain a source of power indefinitely. Much the same could be said of coal, but renewables do not contribute to increased carbon dioxin concentrations in the atmosphere.
