A renewable energy source refers to a sustainable source that can't deplete quickly or last eternally. These sources are the best alternatives to traditional sources of electricity like fossil fuels producing harmful greenhouse gas emissions and increasing global warming.

For example, wind and sunlight are some sources that are continuously being replenished. They are freely available sources that are available in the amount sufficient to meet the rising power demands of the entire nation. Transitioning from non-renewable fossil fuels to solar energy with rooftop solar system providers in Delhi NCR or other renewable sources will help in addressing the climate crisis.

Here are common renewable energy sources used in India:

Solar Energy

It is the most abundant permanent energy source that is available for use in direct and indirect forms. For example, solar radiation, hydro, wind, and more. People using solar plus storage systems can even use solar electricity in cloudy weather, snowy days, at night, and during power outages by harnessing the stored power.

The rate at which solar energy reaches the earth’s surface is around 10,000 times greater than the rate at which it is used. Solar systems transform sunlight into usable and green electricity either through mirrors reflecting solar radiation or through PV (photovoltaic) panels. Most solar panels with an annual maintenance contract for solar system have 25-30 years of lifespan and can produce more power in India due to its geographical location.

Geothermal Energy

This source uses accessible thermal energy or heat from the interior of the Earth to generate energy. Hydrothermal reservoirs are naturally permeable and sufficiently hot reservoirs. When they are enhanced with hydraulic stimulation, they are known as geothermal systems.

Wind Energy

It is a hugely distributed energy source that harnesses the kinetic energy of flowing air by transforming it into mechanical power using wind turbines. The produced mechanical power is converted into electricity using a generator. The average wind speeds differ based on the location.

Tidal Energy

This is some type of hydro energy that utilizes tidal currents to drive turbine generators. Unlike other hydro energy sources, tidal energy is not constant but highly predictable. The energy is produced by an increase in ocean water with rise and fall in tides.

Hydro Energy

Hydro energy sources are more reliable than wind energy. It is a commercially developed energy that can be produced from the energy of water flowing from higher to lower altitudes. A large reservoir creates a controlled water flow to drive a turbine and produce electricity. Hydropower reservoirs can be used for drinking water, drought and flood control, water for irrigation, energy supply, and navigation services.  

Bioenergy

Biomasses like charcoal, wood, etc. are used for producing bioenergy which is used for lighting, space heating, and cooking applications. This energy source converts solid, gas, and liquid fuel from plant materials and domestic and industrial waste into clean electricity at lower environmental and economic costs. However, burning biomass produces greenhouse gas emissions at lower levels.
