    Research Energy is, being able to do work. Most types of energy is either a form of kinetic energy (energy which a body has) or potential energy (The energy possessed by a body). Kinetic energy is energy an object has because of its movement. Energy can be changed from one type to another. When nutrients are used by the body for energy, the amount of energy that the nutrients release are able to be measured in a unit called calories. One calorie, is equal to the amount of energy needed to raise

    What is geothermal energy? : Geothermal energy is thermal (heat) energy that is stored, generated and emanated from the Earth’s core to the Earth’s crust. How is it generated? : The earth core generates geothermal energy through the natural decay of radioactive materials such as Uranium and Potassium. This heat energy is mostly found within magma, which exists below the Earth’s crust. The potential heat energy that exists with the first 100 Kilometers of the Earth’s crust exceeds 500 Kelvin. How

    Renewable energy comes from the sun directly or indirectly. Sunlight, or solar energy, can be captured and used directly for generating electricity, other buildings and lighting and heating homes, and for, solar cooling, hot water heating and a variety of industrial and commercial uses. Wind turbines are used to capture the wind and convert it to energy which is driven by the sun’s heat. Then, the heat from the winds and sun causes water to evaporate. Energy can be captured using hydroelectric power

  • Disadvantages Of Geothermal Energy

    Geothermal energy which is heat energy can be found in almost everywhere on Earth. It is a renewable energy derived from heat deep in the Earth’s crust. The word “geothermal” comes from Greek words meaning “Earth” (geo) and heat (thermal), it means using the nature heat produced inside the Earth. (Davor Habjanec,2008)The use of geothermal energy occurred more than 10,000 years ago with the settlement of Paleo-Indians in hot springs. The technology of geothermal energy improved each year.

    Energy is the prime component of all things running in the universe. Earth uses one very small fraction of the suns energy to sustain its life through the process of photosynthesis. Photosynthesis further leads to production of oxygen and glucose which are the source of survival for humans and all living beings on earth. The energy used in the form of mechanical, kinetic or electrical energy also sources itself from the solar energy or from the product of photosynthesis directly or indirectly (Fossil
