What is a renewable energy:

Renewable energy sources are those sources that replenish themselves and so are essentially inexhaustible, such as solar, wind and biomass energy. While renewable energy sources are not a major percentage of energy sources currently being utilized, their usage is expected to grow substantially, since they are typically less environmentally damaging than traditional energy sources. The future is likely to see more and more utilization of these renewable sources.

Solar Energy:

Solar energy is based on Photovoltaic (PV) that converts sunlight, the most abundant energy source on the planet directly into electricity. PV equipment has no moving part and as a result requires minimal maintenance and have a long life. It generates electricity without producing emissions of greenhouse or any other gases, and its operation is silent.

Today's PV applications are:

• Water pumping
  
• Lighting
  
• Communications
  
• Refrigeration
  
• Household appliances
  
• Utility Grid

Wind Energy:

Wind Energy to generate electricity is most feasible at sites where wind velocities are consistently high and reasonably steady.

Ideally these sites should be remote from densely populated areas, since noise generation, safety and disruption of TV images may be problems.

In the last decade, the wind energy business has seen substantial growth with great advances in the wind turbine and blades technologies along the funds and subsidies found in the EU and North America pushing renewable energy.

In addition, Wind Energy Micro Turbine are being used in remote areas for various task such as pump irrigation and lighting.

Biomass:

The term biomass includes all energy-producing materials that come from biological sources, such as wood or wood wastes, residues of wood processing industries, food industry waste products, sewage or municipal solid waste, waste from food crops cultivated as energy sources, and other biological materials . Both economic and environmental benefits can be achieved when biomass is used as a source of energy for space heating, process heat, or electricity production. If the biomass comes from a waste product, the cost is usually low; this source may have the added benefit of avoiding the cost of disposing of the waste. Utilizing waste biomass sources not only provides an inexpensive source of fuel, but also solves an environmental disposal problem as well.

Four main technologies are available for converting biomass to usable energy forms. The first is simply burning the biomass to provide direct heat for space and process heating or for cooking. The second is burning the biomass to produce steam which is then used to generate electrical energy The remaining two technologies involve converting the biomass to liquid or gas energy forms .
