There is an increase in the projection of future electricity demand across the globe. In the projections from the International Energy Outlook 2010 (IEO2010), the total energy consumption will increase by 49% from 2007 to 2035 (1.4% per year). Based on those reports, it is seen that the use of energy will increase over that time (considering world oil prices will remain relatively high through most of the projection period). There is also an effort being made to search for sustainable and clean energy, like as generated by wind, solar, wave, tide, geothermal and hydroelectricity. This book takes in consideration the following themes: wind power generation, bioenergy, nuclear energy, hydroelectric energy and energy transportation.
