Question
Q.4. What you mean by Renewable Energy Sources? Give the example.
Answer
Renewable Energy Sources are naturally replenishing energy resources that are not depleted by use, such as solar, wind, hydro, biomass, geothermal and tidal energy, as opposed to finite fossil fuels.
Renewable Energy Sources (RES) are energy resources that are naturally and continuously replenished on a human timescale and do not get depleted through use, in contrast to finite fossil fuels (coal, oil, natural gas). Examples include solar energy (photovoltaic and thermal), wind energy, hydroelectric power, biomass energy, geothermal energy, and tidal/wave energy — all of which derive ultimately from the sun's radiation (directly or indirectly, as in wind and biomass), the moon's gravitational pull (tidal), or the Earth's internal heat (geothermal), and are increasingly favored for new power generation capacity due to their low greenhouse gas emissions and long-term sustainability.
