Energy is everything that human needs. Without energy, life here on earth would be impossible. It actually comes in various forms such as chemical, electrical, geothermal, light and nuclear energy. The energy has two types namely, kinetic energy and potential energy. Kinetic energy refers to energy which is actually in motion. One very good example on how to demonstrate it is through running or walking. On the other hand, potential energy refers to energy which can be stored in the energy sources. There are in fact, many ways on how to store energy. There are two categories of energy sources specifically, the nonrenewable sources of energy and the renewable sources of energy. Coal, fossil fuels, natural gas and oil are examples of nonrenewable sources of energy. This type of energy takes a long period of years to be recreated. While renewable sources of energy can be replaced within a short span of time only. Some of the well-known examples of renewable sources of energy are the biomass, geothermal, hydropower, solar, and wind energy.
Earth for energy is already possible nowadays. It is usually known as the earth energy or geothermal energy. It is simply a kind of renewable energy which comes from the heat within the earth. The heat which is being produced by the earth is continuous as well as the replenishing of the water through rainfalls. That is why geothermal energy is said to be under the renewable type of energy sources. As a matter of fact, the earth for energy is being generated at approximately 4,000 miles in the core of the earth. There are various applications of geothermal energy such as for geothermal heat pumps, generation of electricity, and for direct use and district heating systems.
Hydrothermal resources are usually being used in geothermal power plants. These kinds of resources are actually made up of heat and water. Steam is needed in power plants to run the turbines and eventually activate electricity generator. However, some power plants still use fossil fuels to be able to produce steam. There are three kinds of geothermal power plants namely, binary cycle power plants, dry steam power plants and the flash steam power plants.
The binary cycle power plants use water which is in lower temperature to heat up the very low boiling point working liquid. The water and the working liquid should not be mixed up thus, they are held in a separated container. Vapor is then produced by the working liquid which will run the turbine and provide mechanical energy to produce electricity. The dry steam power plants use steam which is piped into a pressurized apparatus to turn the turbine and produce the necessary steps in generating electricity. On the other hand, the flash steam power plants are located at a high temperature underground water places. The water is then heated up until it becomes extremely pressurized which results to a steam. The steam can therefore turn the turbine and produce electricity. Among the three kinds of geothermal power plants, the flash steam power plant is the most common.
Indeed, earth for energy plays a vital role in generating electricity making the lives of the people more convenient and fun. However, conservation of energy should always be put into mind by the humans who consume the energy here on earth.
