Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight‚ wind‚ tides‚ plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002)‚ “Renewable energy is derived from natural processes that are replenished constantly. In its various forms‚ it derives directly from sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal

The Solar System My project is about the Solar System. The Solar System is made up of all the planets that orbits the Sun. The Solar System consists of moon‚ comets‚ asteroids‚ minor planets‚ dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is the more gravity it has. The Sun is the star at the center of the Solar System. After the sun is Mercury‚ the innermost planet in the

Solar System About 4‚700 million years ago‚ the Solar System was just a spinning disc of dust and gas. The dust began to collect together and our Sun formed at the centre. Around Sun‚ lumps of rock joined up to form smaller bodies and‚ like the Sun‚ they heated up. But because they were smaller they soon cooled down and became planets. Sun accounts for 99.85 per cent of mass of the solar system. About 1.3 billion earths would fit inside the sun. The solar system consists of the Sun; the nine planets

SOLAR SYSTEM PLANETS MERCURY • The closest planet to the sun‚ Mercury is only a bit larger than Earth’s moon. Its day side is scorched by the sun and can reach 840 degrees Fahrenheit (450 Celsius)‚ but on the night side‚ temperatures drop to hundreds of degrees below freezing. VENUS • The second planet from the sun‚ Venus is terribly hot‚ even hotter than Mercury. The atmosphere is toxic. The pressure at the surface would crush and kill you. Scientists describe Venus’ situation as a runaway greenhouse

1. Our solar system is made up of the sun and everything that travels around it. This includes eight planets and their natural satellites such as Earth’s moon; dwarf planets such as Pluto and Ceres; asteroids; comets and meteoroids 2. The sun is the center of our solar system. It contains almost all of the mass in our solar system and exerts a tremendous gravitational pull on planets and other bodies. 3. Our solar system formed about 4.6 billion years ago. 4. The four planets closest to the Sun

Solar power satellites Introduction The Sun is a very powerful‚ clean and convenient source of power‚ particularly for satellites. The only thing needed is a means to convert the energy contained in the Sun’s radiation – mainly light and ultraviolet rays – into electrical power. The most efficient way to achieve this today is by using panels composed of semiconductor photovoltaic cells. ‘Solar panels’‚ as they are usually called‚ are now quite a common sight here on Earth‚ but they were first used
