Renewable energy sources are denoted as inexhaustible resources which are naturally replenished on a human timescale, such as: Geothermal heat, rain, sunrays, tides, waves and wind (see more Renewable Energy via Wikipedia).

Renewable energy sources replace conventional energy resources in four following distinct areas:

  • 1.     Electricity generation
  • 2.     Hot water heating
  • 3.     Motor fuels
  • 4.     Rural off-grid energy services

In contrast to other energy sources,
renewable energy resources exist over wide geographical areas, which are naturally powered in a limited number of countries. Renewable energy sources have been deployed rapidly; which creates significant results in energy security, climate change mitigation, and economic benefits. The international public opinion surveys advocate a strong support for promoting renewable sources such as solar power and wind power.
