INTRODUCTION In these days people are trying to find new energy sources. Because present energy sources are running down. So‚ alternative energy is so popular in these days. Because it has no danger to human life like nuclear powerplants‚ it is free to use and it has no waste. There are three types of alternative energy sources: Solar‚ wind and water. This report will be about solar energy. Its purpose is giving some information about solar energy to mechanical engineering students and

Why Do We Need Solar Energy? With the world’s natural resources depleting rapidly‚ humans must find a way to compensate. This society has milked oil‚ coal‚ gasoline‚ lead‚ uranium‚ and many other of these reservoirs in our Earth for hundreds of years and much has been done. Asphalt was used for our roads and highways‚ coal was originally used for heat before there was oil‚ and even water was used as a form of electricity on many rural farms. Luckily‚ more companies around the world are waking

from solar energy is to use photovoltaic cells; magic slivers of silicon that converts the solar energy falling on them directly into electricity. Large scale applications of photovoltaic for power generation‚ either on the rooftops of houses or in large fields connected to the utility grid are promising as well to provide clean‚ safe and strategically sound alternatives to current methods of electricity generation.

is the last idea that comes to mind. The sun is often ignored and so is solar energy‚ but this should change. “The Sun provides 100‚000 terawatts which is about 10‚000 times more than the present rate of the world’s present energy consumption. Photovoltaic cells are being increasingly used to tap into this huge resource and will play a key role in future sustainable energy systems.” (Grätzel 993). The Sun puts off tons of energy and the use of solar power energy could power “the world’s energy consumption”

PASSAGE: Alternative Energy Sources Passage Alternative Sources of Energy Leisa Pichard For six years‚ I lived with my family in a solar-powered home. We met all of our electrical needs with an eight-panel solar array‚ a battery system for storing the electricity‚ and a gas-powered‚ back-up generator. For us‚ solar power was a practical solution to a real problem. For what it would have cost us to have the power company run lines to our remote home‚ we could buy a complete power system

from the sun‚ then water is pumped through these pipes. These panels are positioned in such a way to maximize the absorption of heat throughout the day and can help in reducing the electricity bills. Another approach to harness solar energy is photovoltaic Cells. This method converts the sun’s energy into electricity. These cells are silicon based pieces of materials that absorb the sun’s light. When the sunlight enters the cells‚ it causes the electrons to move. These electrons move in a certain

ARTICLE: NEW GREEN TECHNOLOGY AND ITS BENEFIT 1.0 INTRODUCTION Malaysian must put a ‘price’ on carbon‚ set regulations and pour money into research and development and let Malaysian ingenuity meet the market force for clean energy. This strategy would not only help the world avoid the worst of climate change‚ it will end our dependence on hostile foreign regimes that we rely for oil. Everything that we would actually do in response to climate change would make us healthier as a country

The solar panel industry is a niche market dominated by a small number of large firms. Five out of the top ten biggest players in the industry are Chinese firms. Solar panels capture sunlight and convert it into electricity‚ in one of two forms; photovoltaics OR concentrated solar power. The industry itself is a volume based industry‚ due to the large market share dominated by a small number of players‚ furthermore‚ the solar panel industry not only cooperates with‚ but also competes with other industries
