Non-conventional energy sources are natural resources that are pollution-free and can be used to produce clean energy. Some examples of non-conventional energy sources include: Solar energy: The most abundant energy resource, solar energy can be harnessed even in cloudy weather. Wind energy: Another non-conventional energy source. Biomass: A renewable energy resource derived from plant and animal waste. Hydropower: A mature and widely adopted source of renewable energy. Hydropower is generated by building dams or diverting river water through turbines, which in turn drives generators to... Show more

Non-conventional energy sources are natural resources that are pollution-free and can be used to produce clean energy.

Some examples of non-conventional energy sources include:
Solar energy: The most abundant energy resource, solar energy can be harnessed even in cloudy weather.
Wind energy: Another non-conventional energy source.
Biomass: A renewable energy resource derived from plant and animal waste.
Hydropower: A mature and widely adopted source of renewable energy. Hydropower is generated by building dams or diverting river water through turbines, which in turn drives generators to produce electricity.
Nuclear energy: Energy obtained from the nucleus of an atom. Nuclear energy is obtained by altering the structure of atoms, which releases energy in the form of heat. This heat is then used to generate electric power.
Biogas: A non-conventional energy source delivered by bushes, ranch waste, animal and human waste. 

Other non-conventional energy sources include:
Tidal energy
Geothermal energy
Ocean energy
Bioenergy
