Sustainable Energy Technologies
Sustainable energy is created by methods that do not have a finite capacity and do not cause significant long term environmental damage during production or consumption. Sustainable electricity generation comes from many sources that are becoming more popular as costs come down and awareness increases. Examples of sustainable energy technologies include photovoltaic solar arrays, wind turbines, existing hydroelectric dams, biomass boilers, and tidal generators. Sustainable Energy Technology is not just a future technology, but also a way of financial investments. Sustainable technology is expensive and pays for itself after a few years. Thereafter, however, enjoys a high yield investors. This does not pay for each and every case, but requires knowledge and experience, such as those is shared in the book Fisher Investments on Technology.
Photovoltaic solar arrays capture the sun’s energy and convert it directly into electricity by using specialized panels that react to sunlight by releasing electrons. When captured and banked together into arrays, this form of power generation offers a huge capacity for power generation.
Wind turbines capture the power of the wind and convert it to a rotary motion that is then turned into electricity by use of magnets and coils similar in design to the alternator in a car. Wind turbines offer a large capacity to generate electricity due to their scalability which allows them to be built with blades over 150 feet long.
Biomass is the burning of organic material to produce heat that is used to boil water into steam. The steam is then passed through a turbine to create rotary motion captured as electricity similarly to wind power. Hydroelectric dams use passing water to turn turbines in a similar fashion, and tidal generators are being developed to capture the motion of the waves and the tides and turn this energy into electricity. All of these technologies are gaining in popularity.
