Hello Everyone,👋👋👋
This video is about Top 7 Renewable Energy Resources in the World
@Top Seven

01.Radiant Energy
99% of the cost of normal electricity can be saved by the use of radiant energy. It performs the same functions, but doesn’t possess behavior similar to electricity. Nikola Tesla’s magnifying transmitter, T Henry Moray’s radiant energy device, Edwin Gray’s EMA motor & Paul Baumann’s Testa tika machine all ran on radiant energy. Nikola Tesla built one of the earliest wireless telephones to be based on radiant energy.

02 Compressed Natural Gas
Compressed Natural Gas is a substitute for gasoline, diesel or propane fuel. It is cleaner and safer to use as it diffuses easily into the surroundings if leaked. However, burning it does release a few greenhouse gases in the air. CNG is used in traditional gasoline internal combustion engine cars that have been converted into bi-fuel vehicles.

03.Nuclear Energy
Proponents of nuclear energy contend that nuclear power is a sustainable energy source that reduces carbon emissions and increases energy security by decreasing dependence on foreign oil. Nuclear fission is used to extract energy from atomic nuclei via controlled nuclear reactions. Utility scale reactors are use to produce steam which is then converted into mechanical work for the purpose of generating electricity or propulsion.

04.Solar Energy
The sun offers an ideal energy source, unlimited in supply, expensive, which does not add to the earth’s total heat burden and does not produce air and water pollutants. Solar installations in recent years have also largely begun to expand into residential areas with government offering incentive programs to make “green” energy a more economically viable option.

05.Hydro Electricity
This is the most widely used form of renewable energy. The gravitation force of falling water is the key point in hydroelectricity generation. Small scale hydro or micro-hydro power has been an increasingly popular alternative energy source, especially in remote areas where other power sources are not viable. The hydro power sites has a few major environmental problems like water logging and siltation, Causes loss to biodiversity of fish population and other aquatic animals. It also displaces local people and creates problems of rehabilitation and related socio-economic problems.

06.Tidal Energy
Tidal energy is not a very popular energy source, but has immense potential of becoming one in the near future. Tidal energy can be generated in two ways, tidal stream generators or by barrage generation. The power created through tidal generators is generally environmental friendly and causes less impact on established ecosystems. It is similar to the wind energy. Tidal energy is the only form of energy that derives directly from the motions of the Earth-Moon system. The tidal forces produced by the Moon-Sun in combination with Earth’s rotation are responsible for the tides.

07.Biogas
Biogas is a mixture of methane, carbon dioxide, hydrogen and hydrogen sulphite, the major constituents being methane. Biogas is produced by anaerobic degradation of animal and plant wastes in the presence of water. Anaerobic degradation is to break down the organic matter by bacteria in the absence of oxygen. It is a non-polluting, clean and low cost fuel which is very useful for rural areas. Biogas plants used in our country are of two types; fixed dome biogas plant and floating drum biogas plant.
