Geothermal Energy Introduction The Geothermal is a clean and sustainable (renewable) energy. It has been estimated that the heat of the centre of the earth may reach 6000°C. It has been found that the increases one degree °C for 30-50 meters. The word geothermal is derived from Greek language where the first syllable “Geo” means “earth” and the second syllable “thermal” means “heat”. How it works The geothermal energy should be made useful through electrical generators. We are not free to dig

Energy Fossil Fuels Good Bad and Ugly Abstract Energy is an important part of our everyday lives. Energy can come in many different types‚ and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people ’s bodies with energy. Another form of energy

Clean Energy is Possible First of all‚ energy comes from many sources like oil‚ coal‚ nuclear and wood. These four sources and others are dirty energy. There is clean energy like the solar‚ wind‚ water‚ and kinetic energy. Both of them cause bad or good problems I agree with writer with some points and I disagree with hem on other points. First I agree with him with the point the one that he talks about burning wood and coal causes a lot of pollution in the atmosphere also burning oil is dirty

Forms of Energy Energy exists in many forms‚ and when these change‚ energy is conserved. Different forms of energy include the following: Mechanical Thermal Chemical Electrical Electromagnetic Nuclear energy All of these types of energy have the ability to do work‚ which is also the definition of energy. Additionally‚ they have other properties‚ which are specific to their own specific form. Nuclear Energy Nuclear energy is energy in the

SOLAR ENERGY INTRODUCTION SOLAR ENERGY is the radiant energy that we receive from the sun in the form of heat and light. It is an inexhaustible source of energy. Solar Energy is the ultimate source of most of the sources of energy that we use. The wind energy‚ water energy‚ energy of fossil fuels and the energy in food are due to solar energy. SOURCE OF SOLAR ENERGY The discovery of radioactivity led some scientists to suggest that the energy released during radioactive decay of radioactive

Energy is the ability to do work. It is important because every object we produce requires energy; for example transport‚ growth‚ and development. Humans and all other things get energy from the sun. Some forms of energy are kinetic‚ potential‚ thermal‚ chemical‚ electrical‚ and mechanical. Kinetic energy is the energy of motion. Potential energy is the energy which results from a position or configuration. Thermal‚ or heat‚ energy is the energy a substance or system has related to its temperature

atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

When we think of a roof we think of something that protects and covers the top of a building or structure. But now days‚ there is more possibilities for the use and function of a roof top. It is called a Green Roof. A green roof is creating a rooftop that is covered with plants‚ grasses or small shrubs‚ trees‚ and soil. Green roofs help save energy‚ retain

Green building (also known as green construction or sustainable building) is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life-cycle: from siting to design‚ construction‚ operation‚ maintenance‚ renovation‚ and demolition. One of the reasons why green buildings is important and matters is that green buildings give social benefits to the occupants Provides

Title: Does green energy supplies enough for our life? Nowadays‚ the problem of global warming in all around the earth became more serious. In other countries‚ the iceberg keeps melt because of the global warming causes the temperature of earth increase. So‚ in order to save our environment‚ one of the important ways we can do to save the environment is using green energy. Green energy is the energy that produces little products but no harming the environment. We think that the green energy will supplies
