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

has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat water — for

History of Solar Energy 1767‚ First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven‚ reaching temperatures of 230 degrees fahrenheit. 1839‚ Photovolataic Effect Defined In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect.

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
