  • 1. Renewable energy
    • Definition:-
    • Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable.
    • About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from hydroelectricity.
  • 2. definition
    • New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.8% and are growing very rapidly.
    • The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity and 3% from new renewables.

  • 9. advantages
    • It is highly sustainable as it is derived from sources that are inexhaustible.
    • It does not emit any greenhouse gases or toxic waste making the world a cleaner and safer place.
    • It is highly cost effective as fuel does not need to be brought to sustain the electricity plant.
  • 10. advantages
    • Renewable energy generators such as solar power can be applied to existing buildings making them more environmentally friendly and energy efficient.
    • Some forms of renewable energy such as geothermal steam plants take up less area than larger conventional power plants and can be run day and night.
  • 11. Disadvantages
    • The total potential of renewable energy source as wind power and tidal power is limited.
    • The current capital cost for equipment to convert renewable energy such as solar, wing and tide is very high.
    • Plant for generating power from wind, and tides can be located only in places where suitable conditions of tide or wind exist.
  • 12. disadvantages
    • Solar power is dependent on availability of sunlight. Thus the availability of power fluctuates from zero to maximum every day.
    • Current availability of fuel obtained from plants that can be used as economical energy practically is limited. Though lot of research and development activities is going on around to world to develop plants that could provides suitable fuels economically and in sufficient quantities
