Geothermal energy is the energy which is contained within the earth. The term “geothermal” comes directly from Greek word ge and therme. It is also a sustainable source of energy because the earth produces heat continuously. the earth. Geothermal energy is use to bathe, to create heat for buildings, and to produce electricity.

Geothermal energy is derive from deep in the earth. Slow decaying radioactive particle inside the earth’s core that occurs throughout all rocks, generates geothermal energy. persona

The Earth is comprised of four main layers or parts:

A solid inner core of iron, which is around 1,500 miles wide. A hot outer core magma, which is molten rock, is approximately 1,500 miles in thickness. The magma mantle is a layer of rock that surrounds the core’s outer layer which is approximately 1,800 miles in thickness

A rock-like crust that creates the continents and ocean floors. It’s between 15 and 35 miles in thickness beneath the continents, and up to 3 miles in the oceans.

Scientists have found that the temperature of the Earth’s inner core is around 10,000 degrees Fahrenheit (deg F) that is nearly as hot as the solar surface. The mantle’s temperature ranges between 392degF near the top of the boundary with crust of the earth to around 7,230degF near the mantle-core border.

The crust of the earth breaks into tectonic plates, which are essentially pieces of rock. Magma rises to the surface of the earth at those plates’ edges. This is where many volcanoes take place. The lava that is released from volcanoes is mainly magma. Water and rocks absorb heat from the magma deep beneath. The water and rocks that are deeper underground contain the most extreme temperatures. London

Wind

Air movement is the source of energy. Wind is cause by the uneven warming on the surface of Earth cause by the sun. Since the Earth’s surface is comprise of various types of water and land it absorbs sun’s warmth at different speeds. An example of this unbalanced heating is the wind’s cycle that occurs every day.

The wind cycle that occurs every day. In the day, air over land gets hotter more quickly than water. Land-based air that is warm expands and rises, while heavier cooler air swells into its place and create winds. In the evening, the winds are reversed since air cools faster over land than over water.

Like that the atmospheric winds that circling the earth’s surface originate. Because the area around the equator of earth is hotter than the areas near to the North Pole and the South Pole.

Wind energy to generate electricity

Nowadays most of the wind energy is utilized to produce electricity. Water-pumping windmills were once utilized across in the United States and some still are in operation on ranches and farms predominantly to provide water to livestock.

Solar energy

The sun has produced energy for billions of years and is the principal source of all the fuels and energy sources that we use today. People have relied on solar radiation for many thousands of years to warm and drying fruit, meat and other grains. As time passed, people invented techniques to capture solar energy for heating and then convert it to electricity.

The collection and use of the solar thermal (heat) energy. One example of a early solar energy-collecting gadget is the solar oven (a box designed for collecting and absorption of sunlight). The 1830s were the time when British Astronomer John Herschel utilized a solar oven to cook food on his trip to Africa. Today, people use a variety of techniques for capturing and converting sunlight into useful heat energy to serve a range of reasons.

We utilize solar thermal energy systems to heat our homes. The water used for homes, structures or in swimming pools. So, the interiors of greenhouses, homes and various other structures. However, high temperatures for fluids within solar thermal power stations. Solar photovoltaic systems convert sunlight into electricity.

Photovoltaic solar (P.V.)

Photovoltaic solar (P.V.) equipment, also known as solar cells, convert the sunlight into electric power directly. Small P.V. cells provide power to calculators, watches as well as other small electronic devices. The arrangement of numerous solar cells inside P.V. panels as well as the arrangement of multiple P.V. panels in P.V. arrays can provide energy for your entire home. Certain P.V. power plants possess huge arrays that cover a lot of acres and generate electricity for hundreds of houses. Solar energy has its benefits, however it also has certain limitations.

Utilizing solar energy offers two major advantages:

Solar energy systems don’t emit air pollution and carbon dioxide. And this systems installed on buildings do not have any impact on the environmental.

Solar energy has also its limitations:

Amount of sun light arriving at the surface of the earth isn’t always the same. There is an amount of sun that available to us is different according to where you are located, the time of the day. So, the season of the year, and the weather conditions.

It is estimate that the amount of sun hitting one square foot of surface of the earth is very tiny. Therefore a larger surface area is require to absorb or store an adequate amount of energy.
