The advent of modern technologies has undeniably brought so much comfort to the lives of people. It has supported major industries in so many ways that production has become so large scale enough to meet human needs for agricultural and industrial produces. But one drawback caused by technological advancement is overshadowed by these comforts, and that is depletion of the natural resources. Awareness has been raised regarding this condition that have lead to a revolution in the use of natural resources have been made and brought the enhancement of energy-technologies.
What are the two energy sources renewable-energy? Basically energy resource is either renewable or nonrenewable. An energy source is considered renewable resource only if it is replaced by natural processes and is replenished with the passage of time.Renewable energy on the other hand are resources with sustainable yields. Sadly,the major sources of energy that is used to manage technology are nonrenewable, meaning they can be depleted. They include gasoline, coal, natural gas, diesel, and other products derived from fossil fuels which are non-renewable. The depletion of nonrenewable energy source will be inevitable because it is not replenished. Because of this, attentions are gradually shifted to the use of renewable-energy-technologies.
Sustainable energy which is often regarded as renewable resources is the provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. They include plant matter, solar power, wind power, wave power, geothermal power and tidal power. It usually also includes technologies that improve energy efficiency otherwise called renewable-energy-technologies.
Solar energy is a form of renewable-energy which supports technologies. Solar energy is the energy derived directly from the Sun. It is the most abundant source of energy on Earth and the fastest growing type of alternative energy. Renewable-energy-technologies through solar energy use the photovoltaic cell. It converts sunlight directly into electricity. The Sun yearly delivers more than 10,000 times the energy that humans presently consume.
Wind power is another replenishable source. It derived from uneven heating of the Earth’s surface from the Sun and the warm core. Renewable-energy-technologies supported by wind power is generated by electricity gathered via converting the rotation of turbine blades into electrical current by means of an electrical generator.
Hydropower is a very common resource used to run renewable-energy-technologies. The power is derived from the movement of water in rivers and oceans, which can be used to generate electricity using turbines, or can be used mechanically to do useful work. Another renewable source is geothermal power which is produced via directly harnessing the natural flow of heat from the ground.
