| The global environment is in perennial need of energy without which life cannot be sustained. Noted is the fact that those with energy possess the power and the control of productivity. This persistent, upsurge need of energy has made undue demand on man’s environment, over-exploitation of oil rich zones, deforestation of mass of forest land with attendant degradation, denudation and pollution of the environment that hampers natural environmental productivity and environmental sustainability. The challenge of Green House Gases (GHGs), smog effects, ozone layer depletion, climate change and global warming concerns coupled with high oil prices increases governmental supports and driving increasing renewable energy legislation, incentives and commercialization. Therefore, a urgent shift in paradigm from conventional energy generation which are non-renewable to naturally renewable energy generation becomes expedient. The array of non-fossil fuels like bioenergy (biogas, biofuel), solar energy (photovoltaic), nuclear energy (atomic power), water power, wind power, geothermal and hydrogen generated energy which are renewable need exploration to downplay environmental degeneration, increases job creation, enhances economic buoyancy which invariably enables environmental sustainability. |
