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

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar
