Green technology can be defined as any technology that is friendly to the environment; it may also be called clean technology. The field of "green technology" encompasses a continuously evolving group of methods and materials, from techniques for generating energy to non-toxic cleaning products(Green Technology 2010) Green technology can be found almost anywhere and some examples of green technology are, green energy, green building, green chemistry, and green nanotechnology. Green energy can be any alternative fuel, creating energy and energy efficiency this can be anything from wind turbines to solar energy. Green building can be any kind of structure that is built or renovated with the environment in mind. Green chemistry means that it can be any kind of chemical substance that reduce or eliminate the use of hazardous material. An example of green chemistry is bio pesticides. Green nanotechnology is the technology that is being used to develop the clean technologies that minimize the human health and potential environmental risks. Green energy can be any alternative fuel, creating energy, and energy efficiency. This is a good moment to consider the meaning of renewable energy a little more carefully. It implies energy that is sustainable in the sense of being available in the long term without significantly depleting the Earth’s capital resources, or causing environmental damage that cannot readily be repaired by nature itself ( Lynn, P. 2011). Some examples of green energy are wind turbines, Biomass, Hydroelectric, Geothermal, and Solar. Wind turbines are used for creating energy by using wind. Creating energy from wind has been done for years. In ancient times they used wind power for the propels for their sailboats. But the wind power originated from Persia for grinding wheat. In 1880 the first wind turbine was built specifically for generating electricity in Cleveland, Ohio and it operated for 12 years. Some advantages about wind turbines are that they do not emit any pollutants when ran, and they do not leave behind any dangerous residues. Biomass is a renewable energy source; it comes from living or recently living organism. It is burning the fuel and the oxidative reaction that stored energy as heat. Biomass is carbon, hydrogen, or oxygen based. And Biomass energy can come from garbage, wood, waste, landfill gases or alcohol fuels. Biomass has a small carbon footprint and barely puts off any Co2, biomass also reduce the need for landfills. Hydroelectric is generating electricity from water and it is the largest form of renewable energy in the world. To make hydroelectric you can build a dam on a river with a large drop in elevation. The water gets hold in a reservoir and gravity pushes it through a turbine and that produces the power. Hydroelectric power makes the cost of electricity less and there is also minimal pollution created by using hydroelectric. Geothermal energy comes from the heat from the earth and it is clean and sustainable. Geysers and hot springs are a natural example of geothermal energy. This energy can be used for heat pumps in homes and businesses to cool and heat. Advantages of geothermal energy is that is does not create any pollution. There is also no fuel used to generate the power. And the last example of green energy is solar energy. Solar energy is energy from the sun in the form of heat and light. The solar energy can be used for electricity. Advantages of solar energy are that it is renewable and it will last as long as the sun will last. Solar energy is also nonpolluting. And solar cells are long lasting. Green building is any kind of structure that is designed, built, renovated, operated, or reused in an ecological resource and efficient matter (Cal recycle 2012). Green building has become more popular over the last few years the reason is that a green home is a healthy home. Another reason people are building more green is that it is more affordable to operate and a low...
