Natural sources of Energy

Watch this video for you to understand the Natural sources of energy.

NATURAL SOURCE OF ENERGY​

​​​​​​The primary sources of energy in the environment include fuels like coal, oil, natural gas, uranium, and biomass. All primary source fuels except biomass are non- renewable. Primary sources also include renewable sources such as sunlight, wind, moving water, and geothermal energy. There are 6 more fundamental concepts.

Renewable source is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.

nOn- renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas.

•Types of nature source of energy

 Hydropower

Energy is obtained from flowing water. Energy in water can be harnessed and used in the foot motive energy or temperature differences. The most common application is the dam. Power produced by the fall of water from a higher to a lower level, and extracted by means of waterwheels or hydraulic turbines. Hydro-power is a natural resource, available wherever a sufficient volume of steady water flow exists.

Nuclear power

Is the method in which steam is produced by heating water through a process called nuclear fission. In a nuclear power plant, a reactor contains a core of nuclear fuel, primary enriched uranium. When atoms of uranium fuel are hit by neutrons they fission (split), releasing heat neutrons. Nuclear electrical power produced from energy released by controlled fission or fusion of atomic nuclei in a nuclear reaction. Mass is converted into energy, and the amount of released energy greatly exceeds that from chemical processes such as combustion. They do this by using nuclear reactors in combination with the Rankine cycle, where the heat generated by the reactor converts water into steam, which spins a turbine and a generator.

Solar power

The power derived from the energy of the sun. A radiant energy produced in the Sun as a result of nuclear fusion reactions. It is transmitted to the earth through space by electromagnetic radiation in quanta of energy called photons, which interact with the earth’s atmosphere and surface. SiO2

Wind power

Is the kinetic energy of wind, or the extraction of this energy by wind turbines. Windmill machine that converts wind into useful energy. This energy is derived from the force of wind acting on oblique blades or sails that radiate from a shaft. The turning shaft may be connected to machinery used to perform such work as milling grain, pumping water, or generating electricity. When the shaft is connected to a load, such as a pump, the device is typically called a windmill. When it is used to generate electricity, it is known as a wind turbine generator.

Tides

Is another kind of energy that involves water is tidal energy. Ocean tides can be used to to generate electricity. For this to be possible, a dam must be built across the mouth of a bay. Water then trapped behind the dam at the high tide. At the low tide, the water is allowed to run out through the dam and used to turn electrical generator.
