The Origin of the Solar System A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. The disturbance could be‚ for example‚ the shock wave from a nearby supernova. As the cloud collapses‚ it heats up and compresses in the center. It heats enough for the dust to vaporize. The initial collapse is supposed to take less than 100‚000 years. The center compresses enough to become a protostar and the rest of the gas orbits/flows around it

With an increasing awareness in the fight against global warming and greenhouse gas emissions‚ governments around the world are looking for alternative sources of energy. These include wind‚ solar and hydro energy sources‚ known as renewable sources (Able to be regrown). However‚ one fuel source in particular is currently being used and produced to power both vehicles and electrical generators around the world; biofuels. Biofuels are renewable gas or liquid fuels made from plant matter such as corn

Abstract: Solar energy is quite simply the energy produced directly from the sun and collected elsewhere‚ namely the Earth. Photovoltaic technology directly converts solar energy into electricity. Photovoltaic thin film solar cells are easy to handle ‚ inexpensive and also easy to use. Thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. This paper will discuss the advantages

GEOTHERMAL ENERGY 4 December 2013 Introduction Geothermal is derived from the Greek word ‘geo’ which means ‘earth’ and ‘thermal’ meaning ‘heat’‚ therefore geothermal refers to an energy or heat from the earth. In layman’s terms it is referred to power resulting from the thermal activating within the earth’s crust as a result of volcanic activity. Geothermal energy’s resources range from the surfaces just below the earth‚ to the hot rock‚ which heats water deep beneath the earth

on Monday. There are now worries that the power crisis may stifle India’s growth. "Energy is like blood in your veins. It is as vital as that to the economic growth‚" Rajiv Kumar‚ secretary general of the Federation of Indian Chambers of Commerce & Industry (FICCI)‚ tells the BBC. "If there is a shortage of blood‚ you can’t function - similarly if there is a shortage of energy‚ the economy can’t work." ’Hide behind the numbers’ India’s Ministry of Power has set a goal - Mission 2012:
