TOP RENEWABLE SOURCES OF ENERGY
We are in the 21st century where energy is an inevitable requirement for development. As such, various renewable power generation techniques have emerged; energy sources that are continuously generated and cannot be exhausted.
To help you find a great offer for your electricity and gas, here is a list of the top renewable sources of energy you can consider.
- Hydro electricity
Currently, this is the most widely used source of renewable energy.What actually generates electricity is the force of the falling water.
Hydro electric power is among the mostcommonly used source of energy in rural areas, as most of other energy sources are not viable.
The problem with this form of energy source is, water logging and siltation. It also poses a risk to aquatic animals among other social problems.
- Geothermal
Geothermal energy is one of the cleanest and most sustainable energies we have. It comes from the earth. Geothermal power comes from a range of resources such as shallow ground, hot water and hot rock that are a few kilometers from the surface of the earth.
Deeper beneath the earth’s surface,lies extremely high temperatures of magma. Due to this high temperatures, steam and hot water tries to find its way out from beneath the earth’ssurface. If it does not get any cracks to go through, holes are drilled and pipes fitted and the hot water gushes out. This hot water is used to turn generator turbines which, in turn, produce electricity.
- Solar energy
Solar energy comes from the sun. Solar offers an unlimited energy supply that does not produce any pollutants.
This is the reason why we have seen a sudden increase in the number of corporates andresidential areas making use of solar energy.
Initial costs are expensive but this is an economically viable option that is much cheaper in the long haul.
- Wind energy
This is the conversion of wind into electrical or mechanical energy. These wind turbines are installed on agricultural or grazing land. As compared to most energy sources, wind energy has the lowest impact on the environment.
- Biogas
Biogas is made from the anaerobic degradation of waste materials (both animal and plant waste). It is a mixture of methane, carbon dioxide, hydrogen sulphite, and hydrogen.
Apart from hydro electric power, it is the most commonly used source of energy in rural areas. This is because biogas is clean and low-cost. It, also, does not pollute the environment as other sources of energy do.
- Tidal energy
Tidal energy is one of the least known energy sources but has immense potential of becoming popular in the near future. This energy is directly gotten from the motion of the moon-sun coupled up with the earths rotation. This is what is responsible for the tides.
It is due to this that tidal energy is environmental friendly and has very minimal effects on established ecosystems just like wind energy.
- Biomass
Not to be confused with biogas, biomass is energy gotten from organic matter like wood.Wood is the world largest source of biomass energy. Other sources of biomass include plants and agricultural residue. However, biomass causes water and air pollution so it is advisable to convert biomass into biogas
