What is green technology? “Green Technology is the development and application of products, equipment and systems used to conserve the natural environment and resources, which minimizes and reduces the negative impact of human activities.” (kettha.gov/.my/en/content/defintion-greentechnology) Green technology is extremely important for the planet and us, as human beings. Green technology has given people the opportunity overcome the reaping of natural resources and to build up the environment that the human race is consistently tearing down and damaging. Everything has a cause and reaction. Because the human race is exhausting the natural resources that the earth is providing, we are becoming reliant on something that is not going to last forever. Green technology gives the opinion to find alternatives that will be more environmentally sound and will improve life itself. Within this paper, I will cover green technologies history, what green technology is doing during the present day and what is to come in green technology and what you can do to make an impact.
Many people fail to realize that green technology has been around for a very long time. Although, people in that time did not realize that they were being environmentally friendly. They were simply exploring ways to meet their needs. Many things helped pave the way for Green technology and simply then a better way of doing things and a way to live better from forms of solar power, windmills, to the power of steam, and even electric cars. The power of the sun has been used probably since the beginning of time. In 1839, Alexandre Edmond Becquered discovered a photovoltaic effect which is the process of electricity generated from the sunlight. Over a hundred years later another major breakthrough comes from Calvin Fuller, Gerald Pearson and Daryl Chapin discovered the Silicon Solar Cell, in 1953. After this, around 1956, many things start to change. Solar cells are then being put into everyday objects like toys and radios. To major accomplishments, like the first spacecraft being powered by solar cells. This spacecraft, Soyuz 1, was launched in 1967. From then on, solar power took off in a slow but never ceasing climb. From 1970 to 1990, solar began powering railroad crossings to powering houses. Another major milestone solar energy has passed is a solar car in 1982 created by Hans Tholstrup, the “Quiet Achiever.” To think that then there were energy sources that one could never run out of. Just like being able to harvest the power of the wind. The first windmill was reportedly in Persia in 7 A.D. They used the windmills to water their crops. This passed on through Asia and spread to Africa and other surrounding areas. The Dutch in the 14th century created the tower windmill with the larger lattice work arms with the stretched canvas across. This is the windmill that many people picture when they think of a windmill. With this design, they were now able to move larger amounts of water to where they needed water. By the 19th century the windmill count was a s high as 30,000. The windmill craze caught on in America and spread throughout the Great Plains. The peak time for windmills was from about 1880 to 1935. During this time many farmers relied on these windmills to bring the water. Without water, they have no crops and no life essentially. In 1930, the windmill can to a massive roadblock that halted windmills as they knew it back then. The Rural Electrification Administration made it possible to pump 20 to 30 gallons of water with a simple electric pump. This killed the windmill.
In the mix of windmills and the Industrial Revolution came steam power. In 1698, Thomas Savery coined the first steam powered pump. This then was improved by combining that with pistons and cylinders by Thomas Newcomen and again by James Watt....
