1. Anaerobic Digestion
Anaerobic digestion is a process where microorganisms breaks down biodegradable materials without oxygen. This has been used since the beginning of the 19th century to manage wastes or release energy. The energy industries uses a strain of microbes that can withstand higher temperatures. These microbes efficiently break down organic matter from plants or animal waste and turn it to biogas. Biogas is a perfect substitute for fossil fuel.
2. Biomass Gasification
Biomethane is a renewable natural gas which is produced through the process of biomass gasification. It has been used since the 1900′s to power everything from trucks to agricultural machinery. Biomass gasification was used in order to make up for the petroleum shortage.
3. Geothermal Energy
The use of geothermal energy started with hot springs in the paleolithic times.It is naturally found in the earth’s mantle. This layer is made of molten rock or magma, and is found just beneath the earth’s crust. The heat is produced from the decay of radioactive materials such as uranium and potassium. This heat is then harnessed and used to generate electricity.
4. Hydroelectric Energy
Hydroelectric power uses the principle of transforming potential to kinetic energy. This involves a reservoir of water which contains potential energy and is then released through a penstock. Potential is transformed to kinetic when the water is released, and this is used to turn turbines which are connected to generators. The result, electricity which is then supplied to the community.
5. Marine Energy
Marine energy is a general take on the available ways on how to harness power. One of these is tidal power, which relies on tides. Another would be wave power. The strength of waves is a good source of green energy. People can also take advantage of the varying temperatures of the ocean and the process is called ocean thermal energy conversion.
6. Nano Energy
This is the smallest source of energy because it uses the manipulation of matter in atomic and molecular scale. Nanotechnology deals with the development of technology that is 1-100 nanometres. In relation to green energy resources, it is now being used on solar energy applications. It helps increase the efficiency of harnessing the sun’s power.
7. Nuclear Power
Nuclear energy is derived from the fission of uranium atoms. The fission then produces heat that turn turbines connected to generators. The whole process relies on units of mass that can be converted into units of energy. There has always been a debate about nuclear power being a green source of energy.
8. Solar Energy
The sun has always been a source of energy, the warmth, alone that comes from the sun is an evidence of the power it has. It is also one of the most popular type of green energy. Using solar panels or photovoltaic systems is the easiest way to convert the sun’s energy into electricity.
9. Wind Power
When it comes to wind power, its velocity and force counts in harnessing energy. Wind turbines or wind farms are installed on-shore or off-shore in order to convert the wind’s power to electricity. Wind power is also becoming widespread all over the world and is gradually becoming the most-used source of green energy. The turbines are connected to generators and when the wind blows, the turbines turn. When this happens, electricity is generated.
