The world is getting its oil and gas resources depleted day after day. This calls for other sustainable sources of energy.
'Sustainable energy" means our energy resources are used efficiently to ensure a continuous supply. Using renewable energy instead of fossil fuels will be a better option because they cause less pollution. Renewable energy sources are continually replenished naturally, which means they are sustainable.These include hydroelectric, solar, wind, geothermal, biomass, wave and tidal energy.
Efficient energy management is required to ensure that the energy sources is not wasted and quickly depleted.
