A brief history of solar energy
Throughout the long history of human beings, both periods recorded and prehistoric, the sun has been harnessed. Early homes were located in areas that have received a lot of heat and light and later on the methods of distillation of water and cooking food using only the sun's rays have been developed. Today the sun is seen as an untapped resource is inherent in nature, but millions of people have begun to explore the remarkable benefits of energy Sun.
What exactly is solar energy? In simple terms, there is the energy contained in the intense radiation coming from the sun. Using a number of materials and systems, scientists, engineers and technicians have developed the way home and the owners companies can reduce their energy consumption provided by the use of solar energy.
Today Solar energy is used in many large and small scale applications for everything from heating and cooling homes and buildings, creating hot water, water treatment and sewage, cooking, href = "http://www.ycasolarlightstore.com"> sunlamps, mass production and even electric modes of transport such as cars and airplanes.
real development solar cells required to harness energy from the sun in any way began in the 1800s when a French physicist, observed that there was "photoelectric" effect of sunlight. Let a hundred years later, the photovoltaic effect have been improved, and in fact the material most commonly used - cadmium selenide - were used emotionally.
Things really took off from the years 1950 silicon and other materials have been utilized for residential and commercial solar. It is at this moment and the gas crisis in the 1970s caused many people to discuss energy issues beyond the use of petroleum and petroleum products. At that time, many people have turned their attention to solar energy, water and wind as renewable sources of untapped energy.
Today, scientists and physicists, among many others, continue to expand the applications of energy Sun. It is not unusual to see a complete roof panels with photovoltaic cells, or plant built entirely of huge solar and a single tower to direct energy in a steam room or some other method of conversion of light and heat into usable energy.
With all this research and discovery, it has also become much easier to acquire materials and equipment needed to equip a house or other building with at least one source of solar energy as a hot water system. All this means that the days of total natural energy approaches and affordable for almost any budget.
