Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable.Renewable energy is an alternative to fossil fuels and nuclear power, and was commonly called alternat iue energy in the 1970sand1980s.In 2008, about 19% of global final energy consumption came from renewables, with 13% coming from traditional biomass, which is mainly used for heating, and 3.2% from hydroelectricity.New renewables accounted for another 2.7% and are growing very rapidly. The share of renewables in electricity generation is around 18%, with 15% of global electricity coming from hydroelectricity and 3% from new renewables. Windpower is growing at the rate of 30% annually, with a worldwide installed capacity of 158 gigawatts(GW) in 2009, and is widely used in Europe, Asia, and the United States.At the end of 2009, cumulative global photovoltaic(PV) installations surpassed 21GWandPV power stations are popular in Germany and Spain. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 megawatt(MW) SEGS powerplant in the Mojave Desert.The world's largest geothermal power installation is The Geysers in California, with a rated capacity of 750MW.Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugarcane, and ethanol now provides 18% of the country's automotive fuel.Ethanol fuel is also widely available in the USA.
Climate change concerns, coupled with high oil prices, peakoil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialisation.New government spending, regulation and policies helped the industry weather the global financial crisis better than many other sectors.Scientists have advanced a plan to power 100% of the world's energy with wind, hydroelectric, and solar power by the year 2030, recommending renewable energy subsidies and a price on carbon reflecting its cost for flood and related expenses.Energy development is the effort to provide sufficient primary energy sources and secondary energy forms for supply, cost, impact on air pollution and water pollution, mitigation of climate change with renewable energy.Technologically advanced societies have become increasingly dependent on external energy sources for transportation, the production of many manufactured goods, and the delivery of energy services.This energy allows people who can afford the cost to live under otherwise unfavourable climatic conditions through the use of heating, ventilation, and/or air conditioning.Level of use of external energy sources differs across societies, as do the climate, convenience, levels of traffic congestion, pollution and availability of domestic energy sources.
The book are guiding referral to students, researchers, energy planners, environmental activists and administrators.
