The emergence of modern technology cannot be denied carrying so much comfort for the lives of people. It has supported the large industry in many ways so production has become a large scale to meet human needs for agricultural and industrial products. But one disadvantage caused by technological progress is overshadowed by this comfort, and it is the depletion of natural resources. Awareness has been raised regarding this condition that leads to the revolution in the use of natural resources has been made and brings an increase in energy-technology.
What are two renewable energy energy sources? Basically energy resources are renewable or not renewable. Energy sources are considered renewable resources only if replaced by a natural process and are recharged with the passage of time. Energy that can be updated on the other hand is a resource with sustainable results. Unfortunately, the main energy source used to manage technology cannot be improved, meaning they can run out. They include gasoline, coal, natural gas, diesel, and other products that come from non-renewable fossil fuels. The thinning of non-renewable energy sources will be unavoidable because it is not refilled. Therefore, attention gradually shifts to the use of renewable energy technology.
Sustainable energy that is often regarded as renewable resources is providing energy that meets today’s needs without reducing future generation capabilities to meet their needs. They include plant material, solar power, wind power, wave power, geothermal power and tidal power. Usually also includes technology that increases the opposite energy efficiency called renewable energy technology.
Solar energy is a form of renewable energy that supports technology. Solar energy is energy that comes directly from the sun. This is the most abundant source of energy on earth and the fastest type of alternative energy. Renewable energy technology through solar energy uses photovoltaic cells. It turns the sun directly into electricity. The annual sun provides more than 10,000 times the energy currently consumed by humans.
Wind power is a source that can be recharged. It comes from heating the surface of the earth that is uneven from the sun and warm core. Renewable energy technology supported by wind power is produced by electricity collected through the conversion of the turbine blade rotation into an electric current through an electrical generator.
Hydropower is a very common resource used to run renewable energy technology. The power comes from the movement of water in the river and the ocean, which can be used to produce electricity using turbines, or can be used mechanically to do useful work. Another renewable source is the geothermal power produced through directly utilizing heat flow from the ground.
