fracturing rocks (to obtain a productive gas well) are carcinogenic for human beings. Geothermal energy : This comes from primordial energy of planetary accretion and radioactive decay of materials that exist in regions near the center of the Earth. Until recently, geothermal power systems have exploited

Energies The Renewable Energy Directive of 2009 ( RES Directive) stipulates forms of renewable energies that can be supported in the EU. 7 These forms include wind, solar, aerothermal, geothermal, hydrothermal and ocean energy, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases. 8

irradiation, as well as the 'non-solar' energy sources, i.e. the tides and geothermal power.5 Like conventional energy sources, they can be trans- formed into electricity, heating and cooling, or fuel for transport. Renewable energy sources are widely available in large quantities right across Europe - from

1 Introduction Emerging economies have abundant renewable energy sources, such as solar energy, wind, geothermal, and hydropower as well as non-renewable energy resources, such as petroleum, natural gas, coal, and uranium. However, the production of electricity in both urban and rural areas in

Coal and lignite On the basis of preliminary investigations the conclusion was reached that both domestic animal and human food could be approximated as proportional to population perhaps according to the formula: Fh+a = KPkc where: Fh+a = daily

geothermal systems. Among such new sources, consideration has been given to oil shales and tar sands and to more sophisticated nuclear reactors, but also to sun, wind, and ocean waters. While at the present it appears that none will solve the energy dilemma, each has the potential to make a substantial
