” a clear plastic soda bottle filled with water and installed in the roof as a skylight. The water refracts the sunlight as it streams through the bottle‚ dispersing the rays 360 degrees‚ thereby illuminating the entire room. The recipients of the solar bottle bulbs‚ who pay about $1 for the bulb and installation‚ save money on electricity and cut back on the use of kerosene‚ candles‚ and other fuels that

Energy Conservation SCI/275 Energy conservation is so important. Why you ask? Because of the limited amount of nonrenewable energy sources on Earth‚ it is important to conserve our current supply or to use renewable sources so that our natural resources will be available for future generations. Energy conservation is also important because consumption of nonrenewable sources impacts the environment. Specifically‚ our use of fossil fuels contributes to

SOLAR POWER IN TODAYS WORLD JEROME T. GARDNER COLUMBIA SOUTHERN UNIVERSITY ABSTRACT Since first discovered in the 1860s‚ the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells‚ the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses‚ but is still too expensive and risky for many residents. Researchers

Advantages of and Problems with Solar Energy by Ethan Goffman I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that. – Thomas Alva Edison‚ 1931 The oil embargo of the 1970s prompted a national surge of interest in solar energy. A solar water heater was installed in the White House‚ and photovoltaic panels first came into play‚ notably in California. While previously solar power as a direct source of electricity

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
