Renewable energy has been slowly taking root in our society as more and more governments and institutions are opting for them as an alternative to the conventional fossil fuels. Renewable energy is the best alternative for the purposes of a greener future given the role they play in the reduction of pollutants such as greenhouse gas a major cause of environmental damage. The use of these energy sources also contributes in the reduction for the demand for inefficient and unsustainable fossil fuels. Taking a look at these alternative sources of will help us better understand the magnitude of their efficiency.
Top of the list is definitely solar power which is the most abundant and convenient to use. This rich form of energy is derived from the nuclear fusion a power that comes from the sun’s core. Its collection and conversion can be done in a number of ways ranging from solar collectors for domestic use to complex technologies that directly converts the sun’s rays to electricity with the use of mirrors or photovoltaic cells. A sufficient production of these can sufficiently power our modern day society.
2. Wind Power
Wind is another superb alternative being formed by the changes in atmospheric conditions on the surface of the Earth. The varying temperatures are as a result of sunlight that warms the surface of the Earth hence wind. Wind energy is at times used for pumping water or the generation of electricity with the use of wind turbines that convert the kinetic energy to electric energy. The flip side is that it requires expansive area coverage for the production of a significant amount of energy.
3. Hydrogen and Fuel Cells
Though not strictly regarded as a renewable energy resource, availability of hydrogen and fuel cells are in abundant and emit very low pollution. Hydrogen is typically burned to fuel vehicles whereby water is the only combustion product hence clean which translates to a noteworthy reduction of pollution in urban areas like cities. This hydrogen can also be used in battery like fuel cells for powering electric motors. Whichever the case, with hydrogen, to produce a significant amount of energy requires power in its abundance. So far, promising methods for the production of hydrogen are being invented like solar power that have the potential of drastically altering this picture.
4. Geothermal Power
Geothermal power is the left over energy from the blend of the origins of the creation of our planet and the augmented heat resulting from radioactivity. This energy slowly seeps out everywhere on a daily basis with some areas having a high geothermal gradient which is exploited for the generation of electricity. However, given the limitation of this possibility to a few select locations on the Earth’s surface coupled with numerous technical problems, their utility is limited.
5. Other Renewable energy Sources
Forms of renewable energy are not limited as there are others being discovered such as tidal energy, ocean’s energy and the fusion of hot hydrogen. These are some of the alternative renewable sources of energy that can be used for the generation of electricity. Each of them has been researched and found to have significant drawbacks hence so far unreliable until a proper solution has been found.
Most countries current heavy reliance on fossil fuels such as coal and oil is unsustainable as they are non-renewable, finite and too expensive not forgetting the high environmental damage they inflict. The best option for a greener future lays in the above 5 Renewable Energy Sources as they are environmentally friendly, cheaper and no risk of ever running out.
