Sustainable Energy Sources• Sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs.• Now these days Technologies promote sustainable energy including renewable energy sources. These technologies are also designed to improve energy efficiencyThere are some sustainable energy sources are described here.• Hydroelectricity • It’s a that type of electricity, which produced from hydropower. The cost of hydroelectricity is relatively low. The hydro station consumes no water, unlike coal or gas plants.• Solar energy • It is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic, solar thermal energy and solar architecture• Wind energy • It is the use of air flow through wind turbines to mechanically power generators for electric power. Wind turbines, like aircraft propeller blades, turn in the moving air and power an electric generator that supplies an electric current.• Wave power • This is generated by wind passing over the surface of the sea and capture that energy to do useful work – for example, electricity generation, water desalination and pumping of water.• Geothermal energy • Thermal energy is the energy that determines the temperature of matter. It is generated from radioactive decay and continual heat loss from Earth's formation at more than 4000⁰ c.• Bioenergy Bioenergy is renewable energy made available from materials derived from biological sources. • Tidal power •It’s a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity. It is more predictable than wind energy and solar power.• Carbon-neutral • Carbon-neutral fuels are synthetic fuels (including methane, gasoline, diesel fuel, ammonia) produced by hydrogenating waste carbon dioxide recycled from power plant fuel-gas emissions.• Thank u Follow us on:-
