Many people think solar energy is a new technology, but the history of solar energy goes all the way back to the ancient Greeks and Romans. Even in those ancient times, people understood the power of the sun and uses it to help them in their daily lives.
homes are built facing the sun at just the right angle to reduce the amount of wood needed to heat the home. Wood is a rare commodity from time to time, so the heat from the sun is harnessed to make up for the lack of wood.
While the ancient history is full of sunlight is used, it was not until 1900-by that scientists really began embarking on research that leads to today's solar energy.
Auguste Mouchout understands the need for alternative energy during the industrial revolution. When people use fossil fuels to heat their homes and generate electricity, he realized a long-term effect of this syndrome. When no one listens, he decided to investigate further and was successful in creating the first known solar engine. By 1861, he also invented the steam engine that ran in full sun to power, but thethe price the machine led to failure .
During the past year, 1800, European scientists continued to work with solar energy and reflect on its potential use in real life if you own collection are being perfected.
the first major step in the history of solar energy that we moved towards solar revolution occurred in 1921. Albert Einstein won the Nobel Prize that year for his research into what would later be called photovoltaic cells. His research in the physics of the photoelectric effect was the cornerstone for the creation of the same solar cells used today.
By 1953, Bell Laboratories, designed the first solar cell. cells, created three scientists created an electric current that is measurable - a huge feat in that time. solar cells cost about $ 300 watts for production of electricity from the sun (now that amount is about $ 5 W with regard to technological advances ).
During the 1950s and the 1960-ies, NASA is in the middle of the race to space that deepen the study of solar energy even more. Satellites and spacecraft use the power of the sun to generate electricity, but the technology remains too expensive for anyone but the government used. the tables were turned, however, when the primary energy source, oil is pulled out from under the United States as an affordable source of fuel.
In 1973, the oil embargo caused oil prices to double in 24 hours. In a panic, government officials were quick to search for alternative energy sources and development of Bell Laboratories in 1953 came to mind. The government has invested large amounts of money in design and power of the sun was soon realized.
the future history of solar energy
the future is brighter than ever before, for solar energy. Price of solar cells falls and fewer units are now very affordable for anyone and everyone to buy. Keychain units can be purchased for less than $ 20 USD, and have the ability to charge cell phones in less than 24 hours. While this May seem like a long time, solar cells are often about one inch by one inch in size.
solar powered car, collecting solar power windows, building materials, and not far from the mainstream of development. The sun is a renewable energy source that can provide more energy than any fossil fuels on the planet.
