1. Wind energy :-
Wind energy is one of the fastest-growing renewable energy sources after a number of countries have turned to the technology in an effort to reduce their emissions.
The process involves using wind to produce electricity through the use of the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems.
2. Solar energy :-
Solar energy involves converting energy from the sun into thermal or electrical energy using one of the cleanest and most abundant renewable energy sources.
Alongside wind, solar photovoltaic (PV) is the most established of the low-carbon energy technologies and, as it grows in scale, the costs of development are coming down.
3. Hydro energy :-
Hydroelectricity is produced by harnessing the gravitational force of flowing water. The technology is broadly classified into four categories – conventional (dams), pumped-storage, run-of-the-river and offshore marine (tidal).
Compared to fossil fuel-powered energy plants, hydropower plants emit fewer greenhouse gases – but the construction of the plants and dams requires huge investment.
4. Biomass energy :-
A collective term for all plant and animal material, biomass can take many forms – from plants and wood, to animal and agricultural waste.
In power generation it is commonly used as wood pellets that are harvested from forests and burned to release energy.
5. Tidal energy :-
Tidal energy is generated from converting energy from the force tides into power and its production is considered more predictable compared to wind energy and solar power.
Although the world’s first large-scale plant of its type became operational in 1966, tidal power is still not widely used.
