Its current uses include heating buildings (either individually or whole towns) raising plants in greenhouses drying crops heating water at fish farms and several industrial processes such as pasteurizing milk.

How is geothermal energy use around the world as renewable energy source?

Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing to heat buildings and to generate electricity.

How efficient is geothermal energy compared to fossil fuels?

A geothermal system is three to four times more efficient than the most efficient fossil fuel system. Because geothermal systems do not burn fossil fuels to make heat they provide three to four units of energy for every one unit used to power the system.

Is geothermal energy safer than most other energy sources?

The U.S. Environmental Protection Agency has called geothermal heating the most energy-efficient and environmentally safe heating and cooling system.

Is geothermal energy a viable source of energy for most people?

Why is geothermal energy a renewable resource? Answer: Because its source is the almost unlimited amount of heat generated by the Earth’s core. Even in geothermal areas dependent on a reservoir of hot water the volume taken out can be reinjected making it a sustainable energy source.

Which energy source is renewable apex Brainly?

The most popular renewable energy sources currently are: Solar energy. Wind energy.

Where does the heat from geothermal energy come from Apex?

Heat used for geothermal energy comes from molten rock called magma beneath the earth’s crust.

Why are renewable sources of energy better than nonrenewable sources apex?

Renewable sources of energy are better than nonrenewable sources because they refill themselves over a short period of time. … The use of renewable sources of energy means that as we use it the Earth refills it. Like hydropower fueled by water or solar power fueled by the sun.

How does hydroelectric energy work?

Hydroelectric power is produced with moving water

At hydropower plants water flows through a pipe or penstock then pushes against and turns blades in a turbine to spin a generator to produce electricity. … Most U.S. hydropower facilities have dams and storage reservoirs.

What is geothermal energy plant?

Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth’s internal thermal energy). … Hot water or steam is extracted from the Earth through a series of wells and feeds the power plant.

What is the difference among the kinds of geothermal power plants?

There are three types of geothermal power plants: dry steam flash steam and binary cycle. Dry steam power plants draw from underground resources of steam. … Flash steam power plants are the most common. They use geothermal reservoirs of water with temperatures greater than 360°F (182°C).

How is hydroelectricity produced Class 8?

Hydroelectricity is produced from the energy possessed by water falling from great heights. River water is stored in dams. … The moving blades are connected to a generator which produces electricity from this energy. This electricity is called hydroelectricity.

Why is it that hydroelectric energy considered renewable form of energy?

Hydroelectric energy is a form of renewable energy that uses the power of moving water to generate electricity.

How mechanical energy differs from the hydraulic energy?

Answer: 1) Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. … A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy.

Are geothermal and hydroelectric energy good as source of energy?

Geothermal and hydroelectric are renewable sources of energies and produce “clean” fuel sources. … Geothermal heat pump systems can heat and cool buildings and can also provide a source of hot water.
