There are numerous ways of creating green energy which are considered to be harmless and environmentally friendly. They are clean & renewable since they do not deplete nor do they pollute. Here are the best 10 types of green energy:

1. Nuclear Power

This energy is created by atomic nuclei through a controlled reaction. Nuclear fission is the only method used to produce nuclear energy. In 2007, over 14% of the World’s total energy was produced through nuclear energy. However, this form of energy requires great attention since a simple mistake would spell disaster.

2. Compressed Natural Gas

Also known as CNG, it’s a fossil substitute for diesel, gasoline & propane fuel. Compared to oil, it is more environmentally friendly though it produces greenhouse gases. Natural gas is lighter than air and natural gas cars are being encouraged by numerous countries. Canada is leading in natural gas production.

3. Biomass

Biomass refers to living & dead biomass used as fuel/ for industrial production. Biodegradable waste is burnt to hear water that becomes steam. The steam is used to rotate turbines which rotate motor to generate electricity. However, this form of energy has not been implemented to a larger extent.

4. Geothermal Power

Geothermal energy is a very efficient and powerful way of extracting renewable energy from the ground. It can be performed on small scale to heat houses or on large scale to produce electricity. It is cost effective since the only cost involved is drilling and maintenance. So far, five countries inject more than 15% of geothermal electricity into their national grid. However, this energy is limited to geographical location.

5. Radiant Energy

It is a natural energy that performs similar functions as the electricity we use but uses less than 1% on operational cost. It behaves differently from the normal electricity making the scientists have numerous misunderstanding of it. This form of energy was discovered by Nicola Tesla in the early 1900s.

6. Hydroelectricity

This is the production of electricity from water. The water falls through gravitational pull and rotates a turbine which in turn rotates motor hence producing electricity. This form produced 19% of the world’s electricity as per 2003 survey. Small motors can be installed without the need of a reservoir while a huge motor require a huge reservoir. This is a very good source for Electrical Power.

7. Wind Power

This is the conversion of wind energy by wind turbines into wind energy like electricity or mechanical energy. Huge wind farms are connected to the grid while small turbines generate energy for local use. Although wind helps produce 1.5% of the World’s energy, it’s growing rapidly having doubled between 2005 & 2008.

8. Solar Power

Photovoltaic (PV) solar power harnesses the sun’s energy to produce electricity. It is the fastest growing energy sector and has seen new technologies develop at a fast rate. PV is mainly used to power small & medium homes and most governments have put incentives to encourage their use.

9. Wave Power

It’s the transport of energy by the ocean surface waves, & capture of energy to do useful work like electricity generation, pumping of water into reservoirs and water desalination. However, wave energy is hard to harness due to the unpredictability nature of the waves.

The power systems consist of a floating device that generate energy through mechanical movements or snake motions.

10. Tidal Power

It’s generated either by barrage generator or by tidal stream generator. Similar to the wind turbines, tidal stream generators rotate underwater being driven by the moving water. Water flow being more predictable than wind & solar energy, it is going to dominate in future power production.
