Constant rising demand for energy has been witnessed from all across the world that has brought the conventional energy resources under pressure. At present, the maximum of the entire primary demand for energy is being fulfilled by fossil fuels. But the rising concerns about environmental pollution from the conventional energy resources and the consequent depletion of finite sources have resulted in a shift to the green energy resources. Furthermore, several initiatives and support by the government aimed at energy-efficient developments and spending in renewables by private as well as public sectors have turned out to be proactive in fulfilling the continuously increasing demand for energy, thus propelling the energy & mining industry.
