Write any 2 examples of clean energy sources for generating electricity. Why do we call them clean sources of energy?
Answers
Answer:
solar, wind.
Renewable energy, often referred to as clean energy, comes from natural sources or process that are constantly replenished.
Clean energy is known to be Renewable energy. They're usually found in the wild. We can say that a renewable energy source is a natural resource that replenishes depleted or consumed amounts of resource within a finite time interval on the human time scale, either through natural reproduction or other recurring processes. Renewable energy sources include solar, wind, biomass, geothermal, and water (hydro).
Explanation: 1) Solar Power
The sun's energy is referred to as solar energy. Solar collectors capture the radiant light and heat energy. Through a series of panels or mirrors, the sun's energy can be caught to provide power or heat.
2) Wind Power
Wind power, often known as wind energy, is the utilisation of wind to deliver mechanical power to electric generators via wind turbines, allowing them to perform tasks such as milling and pumping. Around a rotor, the wind hits two or more propeller-like blades. This rotor is attached to the generator's main shaft, such that when the rotor rotates, the shaft rotates as well, producing electricity as the generator runs. These turbines are mainly found in high-altitude locations.
3) Energy from Geothermal Sources
The Earth's own thermal energy is stored within it. Geothermal energy is the energy created from the thermal energy stored in the earth. Hot springs and volcanoes collect thermal energy, which is then used directly by industry to heat water and for other uses.
