Non-conventional energy sources are those that are present in nature, enjoy a huge supply, and cannot be extinct. These are also known as renewable sources of energy. Some examples of non-conventional sources of energy are solar energy, wind energy, and tidal energy. Most of these energy sources are good for the environment and are present in a good quantity. Non-conventional sources have gained more popularity in the present time as the world becomes more conscious about the environment and promotes sustainability. 

Solar energy

• The energy that the earth receives from the sun is called solar energy
• It is utilized in solar cells to deliver power. Many of these cells are joined into sunlight based chargers to produce power for warming and lighting reasons
• It can likewise be utilized in sun-powered warmers, sunlight based cookers and sun based dryers other than being utilized for local area lighting and traffic light

Wind Energy 

• The wind is an inexhaustible source of energy. Windmills have been utilized for crushing grain and lifting water from wells
• The wind is utilized to deliver power employing the motor energy made through movement of air. This is converted into electrical energy using wind turbines
• Wind ranches having groups of such windmills are situated in waterfront locales and in mountain passes where solid and consistent breezes blow
• Wind farms found in the Netherlands, Germany, Denmark, UK, USA, and Spain are noted for their wind energy production

Geothermal Energy

• Heat energy acquired from the Earth is known as geothermal energy
• The USA has the world’s biggest geothermal power plants, followed by New Zealand, Iceland, the Philippines and Central America
• In India, geothermal plants are situated in Manikaran in Himachal Pradesh and Puga Valley in Ladakh
• Geothermal energy in the form of hot springs can be used for cooking and heating. Even these areas have become tourist destinations, especially in countries like Sweden

Tidal Energy

• The energy produced from tides is called tidal energy
• Tidal energy can be outfitted by building dams at tight openings of the ocean. During elevated tides, the energy of the tides is utilized to turn the turbine installed in the dam to deliver power
• Russia, France, and the Gulf of Kachchh in India have colossal flowing factory ranches

Biogas

• Natural waste like dead plant and animal material, animal fertilizer and kitchen waste can be changed into a vaporous fuel called biogas
• Biogas is fundamentally a mix of methane and carbon dioxide
• It is used as a fuel for cooking and lighting and creates a tremendous measure of natural compost every year.

Hydro  Power

• Energy,  which is produced from running water which falls from heights and  turns the turbine
•  It is the energy generated by conversion of kinetic energy of water into mechanical energy of a turbine  to  electric energy, ultimately
•  Hydropower is considered as the cheapest and cleanest source of energy
•  India has a huge potential of hydropower energy. Generally it requires, construction of hydropower plants, dams etc 
• India is the world’s third-largest producer of hydropower energy. The country has around 197 hydropower plants.

Conclusion

Energy is the essential commodity for human life. It is used for industries, households, the transport sector and many more. It is the lifeline of humans and the economy. Basically, energy has conventional and non-conventional sources. Non-conventional sources are those which are renewable in nature and abundantly found. Solar energy, wind energy, tidal energy, geothermal energy, biogas etc are the examples of non-conventional sources of energy. These sources of energy are Inexhaustible and environment friendly. Due to the hazardous effects of conventional sources of energy, Non-conventional sources of energy are promoted by the government. Now this energy is generated on a small scale, but in the future non-conventional sources of energy have great potential if the right kind of technology is developed.
