Green Energy is energy that can be extracted, generated, and/or consumed without any significant negative impact on the environment. The planet has a natural capability to recover which means pollution that does not go beyond that capability can still be termed green.
Green power is a subset of renewable green energy and represents those renewable energy resources and technologies that provide the highest environmental benefit. The US Environmental Protection Agency defines green power as electricity produced from solar, wind, geothermal, biogas, biomass, and low-impact small hydroelectric sources. Customers in developed countries often buy green power to avoid environmental impacts and its greenhouse gas reduction benefits.
The significance of green energy is that it is sustainable; hence its demand is increasing day by day. However, challenges related to it are also rising along with growing demand. Due to this burgeoning demand for energy and increasing cost competitiveness of renewable sources of energy vis-a-vis conventional sources will see the 'global green energy renewables' industry double in the span of ten years experts suggest.
It is expected that use of renewable green energy, particularly wind and biomass but not excluding photovoltaic, to expand significantly, as these sources are now cost-competitive with coal, gas and other traditional sources. Green energy is fast becoming an essential part of a diversified energy supply portfolio. Power shortages and energy security are both critical issues for Pakistan's rapidly growing economy. Wind is already cost-competitive with heavily subsidised fossil fuel-based energy in several countries and its competitive position will only improve over time. In Pakistan there is growing need for an effective national energy policy, co-ordination amongst key stakeholders across the provinces, investments in the grid and policy stability for wind power to fulfil its potential in Pakistan.
