  • With global populations on the rise and the increasing threat associated with climate change, the need for the development of low emission energy resources is clear. Geothermal energy, which originates from the underground heat of the earth (Sankaran, 2002), has the advantage of being a low-emission, baseload energy resource. Unlike other alternative energy resources, geothermal energy production does not fluctuate with time of day or season.

  • Renewable Energy is energy generated from natural resources - such as sunlight, wind, rain, tides and geothermal heat - which are naturally replenished. In 2008, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation), followed by solar hot water/heating, which contributed with 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.

  • This paper summarizes the presentations and discussion at the Energy Options for the Future meeting held at the Naval Research Laboratory in March of 2004. The presentations covered the present status and future potential for coal, oil, natural gas, nuclear, wind, solar, geothermal, and biomass energy sources and the effect of measures for energy conservation. The longevity of current major energy sources, means for resolving or mitigating environmental issues, and the role to be played by yet to be deployed sources, like fusion, were major topics of presentation and discussion....

  • Energy is defined as the ability to do work. Energy is found in different forms, such as heat, light, motion, and sound. There are many forms of energy, but they can all be put into two categories: kinetic and potential. Electrical, radiant, thermal, motion, and sound energies are kinetic; chemical, stored mechanical, nuclear, and gravitational energies are potential forms of energy

  • Renewable energy sources such as solar power, wind power, hydroelectric power, geothermal power, and so on have attracted much attention as alternatives to fossil fuels, because toxins and pollutants are not produced by these sources. For this reason, these energy sources have come to be known as clean energy.

  • The utilisation of renewable energies is not at all new; in the history of mankind renewable energies have for a long time been the primary possibility of generating energy. This only changed with industrial revolution when lignite and hard coal became increasingly more important. Later on, also crude oil gained importance. Offering the advantages of easy transportation and processing also as a raw material, crude oil has become one of the prime energy carriers applied today.

  • Geothermal energy is the internal heat of the Earth. For centuries, geothermal energy was apparent only through anomalies in the Earth's crust that allow the heat from the Earth's molten core to venture close to the Earth's surface. Volcanoes, geysers, fumaroles, and hot springs are the most visible surface manifestations of these anomalies. Geothermal energy has been used for centuries where it is available for

  • In electrical power generation system the present trend is to maximize the renewable energy penetration ratio as much as possible. Among the renewable energy sources such as wind, solar, biogas/biomass, tidal, geothermal, etc., wind energy has the huge potential to play an important role in energy market along with conventional energy sources. Therefore, reasonably the research on wind power is progressing rapidly.

  • Solar energy refers primarily to the use of solar radiation for practical ends. However, all renewable energies, other than geothermal and tidal, derive their energy from the sun. Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight. Active solar techniques use photovoltaic panels, pumps, and fans to convert sunlight into useful outputs.

  • Renewable energy technologies—including solar, wind, biomass, geothermal, and hydropower—are in many ways attractive to policy makers who must address these market disruptions and the economic and social strife they can create. Renewable energy technologies are advantageous because they are immune to price shocks from fuel supply constraints and cartel pricing. Furthermore, renewable energy resources are much more environmentally benign than their conventional counterparts, such as coal, nuclear, and petroleum products.
