SOLAR ENERGY Our environment is in a fatal state any move could cost us the world. We need to work with the environment and not against it‚ we need to use what it is giving us every day and not every million year‚ once it is gone it is gone. Instead of using fossil fuels and having them burn to waste use solar energy and use what the sun gives us every day. Solar energy is an effective alternative source because there is very little pollution‚ they cut down on fossil fuels and are cost effective

Types of Alternative Energy “Every day‚ the world produces carbon dioxide that is released to the earth’s atmosphere and will still be there in one hundred years’ time. This increased content of carbon dioxide increases the warmth of our planet and is the main cause of the so called “Global Warming Effect.” One answer to global warming is to replace current technologies with alternatives that have comparable or better performance‚ but do not emit carbon dioxide. We call this Alternate Energy.” (Alternative

Geothermal energy vs coal powered energy‚ what say you? Geothermal energy is a renewable source of energy generated and stored in the Earth. Coal powered energy is a source of energy produced from the natural resources of the Earth. Geothermal energy and coal powered both have many uses especially in generating electricity. In this field‚ they are similar as electrical energy is generated in a similar concept. Heat from the Earth’s crust and heat produced during the burning of coals are both used

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

History of Solar Energy 1767‚ First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven‚ reaching temperatures of 230 degrees fahrenheit. 1839‚ Photovolataic Effect Defined In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect.

Americans today have their negative and positive sides to them. For example‚ many Americans‚ like my father‚ focus on the any positives of the people. He sees the good in everyone‚ and he is always providing sweet southern hospitality to his neighbors and community members. Another positive of Americans is the passion that every soul carries with them; Americans strong belief in freedom and justice always brings the great nation together‚ this love is so great that often times this patriotism for

that of energy sources to power an increasing global demand. Traditionally‚ humans have converted energy from natural resources like coal and natural gas for use. However‚ these sources of energy are both nonrenewable and cause large amounts of pollution. As we progress through the 21st century‚ renewable energy sources like solar and wind energy will see increased use to replace traditional sources. One of these sources‚ wind energy‚ is seeing a rise in development because it is a source of renewable

discussed in Detail about Wind Energy and the production of electricity from moving vehicles. So first we defined Energy. Till Now we have studied that energy is the ability of a body to do work .it can also be defined as the ability of a body to bring some change is the energy of that body. Energy is very necessary for human beings; every thing in the universe possessed some energy. There are two main kinds of Energy 1. Kinetic Energy 2. potential Energy Kinetic energy is produced by the motion
