A simple definition of geothermal energy is heat energy obtained from the earth. It may surface itself through the form of hot springs which have been used for cooking, heating and bathing. The temperature in the interior of the earth rises steadily with depth. Like other forms of renewable ...

Nuclear power is the energy that heat and lights our cities and towns. It has simplified our lives and made it easier to do everything in life. Nuclear power plants produce electricity by harnessing the energy stored in the nuclei of atoms of naturally occurring radioactive elements like ...

Wind energy has been harnessed for hundreds of years. Ancient civilizations have created primitive windmills in order to provide a better way of irrigation and pumping water from the ground. In the industrial era, wind energy was used to power pumps in coal mines and mills for grinding grains. ...

Solar energy is the energy from the sun that is converted into other forms of energy such as heat, light, and electricity. Solar energy can also be used to produce renewable electricity. This type of clean energy from the sun is being harnessed in a number of ways for use in homes, businesses, and ...

What is the solution to the increasing scarcity of fossil fuels? Is it time to say goodbye to fossil fuels, since they are not possible to replace? For more than a century, they have been the primary sources of energy. Fossil fuels, which are finite resources, provide more than 80% of the ...

The electricity produced by hydel power is very cheap and reliable. It is, however, restricted to the areas near rivers and seas where dams can be built. The hydroelectric plants can be built in such a way that they do not affect the flow of the river. Dams also play a very important role in ...

Natural gas is a fossil fuel found with petroleum deposits; it is an odorless, tasteless, colorless gas released when crude oil is brought to the surface. Because natural gas burns cleaner than other fossil fuels like coal and oil, many countries around the world are using it as a domestic and ...

Petroleum or crude oil is a complex mixture of hydrocarbons and a valuable natural resource. Petroleum is found in big oil fields under the ground, off-shore and at coastal locations The oil field extraction process involves drilling. Oil is transported to refineries to be processed and ...

Coal is found in nature too. The abundance of combustible material in coal is what makes it an important domestic fuel resource. However, the use of this fossil fuel has led to negative effects on the environment. Electricity from coal is called thermal power. The coal was formed millions of ...

Energy sources which we can use to power our homes and to transport us from one place to another. These include coal, oil and natural gas. They are called conventional sources because they have been used for a long time without much change. Conventional Sources Of Energy Fossil fuel is one ...
