List of 12 Alternative Green Energy Sources

Are we polluting the world too much? The world can be a better place by using renewable energy sources and making it green and more environment friendly. Because non-renewable sources are scarce and continue to deplete due to immense demand, green and harness renewable sources are discovered to satisfy needs of humans all around the globe. Green Energy sources are obtained naturally and do not tend to pollute the environment by omission of toxic material and gases.

Alternative Green Energy SourcesThe attributes of Green Energy Sources make it limitless, and it does not tend to suffer from exhaustion, depletion, leakage or contamination. It is very important to state that the best part about renewable energy is that prices continue to fall and plentiful clean energy becomes affordable and continues to be the more economic option.  Here is a list of 12 Green Energy sources which can be frequently recycled.

1. Solar Energy

It is one of fastest growing energy sources around the globe, widely used by new technologies. It is not of much surprise that the solar power is one of the most powerful sources of energy. No matter what the purpose may be; heating, lightning, cooling or generating electricity, sunlight can be used to do it all. Photovoltaic (PV) Solar Power is a method used by researchers to harness the energy from sun rays to generate electricity, by using either active solar or passive solar type. As a form of renewable energy source solar cells are proving to be easier to conveyance, effective and efficient, allowing for easy installation and even flexible to use.

2. Wind Energy

Since centuries wind power has been used to drive windmills and sail ships, and today this natural power is being used to generate electricity. The speed of the wind is converted into electricity and consists of around twenty five percent of energy being produced by this power. Out of all the renewable energy sources, wind energy has the lowest environmental impact.

3. Hydroelectricity

Water rushing downstream acts as a powerful force. The water in lakes and oceans is constantly evaporated by the heat of the sun which makes it extremely renewable. All round the year, the water is purified itself due to the cycle of nature. Once a hydropower structure is created, the gravitational force of falling water helps to produce electric current, without any waste or discharge, which proves it to be highly environmental friendly.

4. Biomass

Dead material and plants can also help in producing renewable energy. The photosynthesis process of plants has the tendency to generate energy, and when the plants burn they incline to release their energy, which is renewable. This energy produced from the burning of plants can be used as an alternative to fossil fuels in order to generate electricity, manufacturing goods, and fueling vehicles.

5. Biofuel

Scientist found out that they can generate a type of alcohol called ethanol from the fermentation of sugar in plants. The interesting thing is that they discovered that this fermentation can produce power in the form of biofuel. Biofuel is renewable source of energy generated from crops that usually have a high content of starch and sugar.

6. Hydrogen

This source is still at its initial stages but holds a great potential as an energy basis and fuel. Hydrogen is an important element of water, which we have plenty all over the world. Hydrogen when separated from other components can be used to produce electricity and satisfy needs of gas and petroleum.

7. Geothermal Energy

It is one of the most efficient ways to extract renewable energy through natural processes. Heat produced beneath the surface of the earth can be released through digging to provide people with vast amount of natural energy. Geothermal Power is not just environmental friendly, cost effective, reliable and long lasting but can power entire cities and towns with a large plant.

8. Tidal Power

Tidal generators rotate underwater and have the tendency to generate electricity. This energy source is considered to be more environmental friendly as it hardly puts any impact on the ecosystem. The Earth-Moon system and the Earth-Sun system directly produce these tides in combination with the movement of the earth making it ever lasting form of generating electricity.

9. Wave Power

Wave Power is not a common source of producing renewable energy but is highly capable of generating electricity. The mechanical energy is created by the mounting and sinking of the waves through a buoy-like structure which is transformed into electricity that is then transmitted to shore over a submerged line.  It is quite difficult to harness wave energy due to the randomness of the ocean and wave course but even then the energy of the ocean waves can be captured to do beneficial work.

10. Radiant Energy

This is a sort of natural energy which acts almost but not exactly like electricity at a less low cost than normal electricity. It can be gathered directly from the environment or with fractionation can be pulled out from ordinary electricity.

11. Nuclear Energy

Electricity can be produced by a process of fission of atoms of uranium. Fission is capable of producing steam energy that can be used to produce electric current. However, there is a long debate! Is nuclear energy renewable and green?

12. Nikola Tesla

Nikola Tesla is a famous source of free and renewable energy. He is the key inventor to the findings of major sources of renewable energy like wind, geothermal and ocean. It was by his efforts that people started considering the existence and importance of these alternative ways to produce energy.

Renewable energy has the advantage to come from natural sources that are continually and sustainably refilled. The sources mentioned above will make our world a healthier place and prosperous by refining our air quality. This will reduce our reliance on non-renewable fossil fuels helping us protect environment and protect habitat.
