It is a fact that, alternative energy sources are being produced
for a long time to substitute non-renewable sources such as oil and
natural gas. As of 2018, it is foreseen that main non-renewable
energy sources, oil, natural gas, and coal, will be exhausted
respectively in 36, 57 and 119 years.1 85% of the energy
is produced from non-renewable energy sources which results in
hazardous consequences. Therefore, it is not surprising that the
tendency towards alternative sources is gaining momentum. One of
the hazardous consequences can be expressed as "damage to
nature". The debate on global warming is beyond dispute;
because of the overheating, the glaciers are melting and the
conditions of the seasons are noticeably changing. Moreover, global
warming is also one of the reasons that accelerates the direction
towards alternative energy sources. However, the acceleration is
not that fast.
