Turbine blade design for wind power generator
The conventional energy sources for instance coal, oil, natural gas, or nuclear are limited and cause pollution. Contrariwise, the renewable energy sources like wind, fuel cell, solar, biogas/biomass, tidal, geothermal, etc. are clean and in abundance in nature.
Amid renewable sources the wind energy has the massive possible of becoming a major source of renewable energy for the modern world.
Wind power is a clean, carbon-free technology, based on netting the energy from natural powers and has negative impact to the environment (Geißler 51). In 2012, 27 GW wind power had been installed globally, bringing world-wide connected capacity to 120.8 GW (GWEC publication 2013). It is an increase of 36% compared with the 2007 market, and represents a total increase in the universal installed capacity of about 28.8%.
As evidenced in this illustration, it is clear that wind power is going to take over the renewable as the conventional energy market in sooner future.
Wind energy is the only power generation technology that can deliver the necessary cuts in CO2 emissions from the power sector in the critical period up to 2020, when greenhouse gas emissions must peak and begin to decline if we are to have any optimism of eluding the worst effects of climate change .
The 120.8 GW of global wind aptitude connected by the end of 2008 produced 260 TWh of electricity and store 158 million tons of CO2 every year (GWEC publication 2013).
