Resource
Renewable resource
Definition:
any natural resource that can
replenish itself naturally over time, as wood or
solar energy;
Non-renewable energy
Definition: any natural resource from the Earth
that exists in limited supply and cannot be
replaced if it is used up; also, any natural
resource that cannot be replenished by natural
means at the same rates that it is consumed

Pakistan

Pakistan is developing a wind power energy project, which could help
solve some of the country's electricity supply problems.Pakistan is to
work with the Chinese government to install and maintain 14 small
wind power plants to generate electricity in the southern coastal region
of Sindh and Balochistan.
These two regions currently have no access to electricity and would be
best suited to wind power.
"It is the supply issue that is a problem, particularly in the remote area.
To supply electricity from the grid it is not even sometimes technically
feasible, not to talk about economically feasible, to get back the
revenues and for those areas definitely the renewable industry can
play a part," Dr Ishtiaq Qazi, director general of the Pakistan Council
for Renewable Energy Technologies in Islamabad told the BBC's
World Business Report.
The project consists of eight 300 watt turbines and six 500 watt
turbines.

Benefits of Wind Power
Wind Power
Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural
Issues of Wind Power
Wind turbines can fall, Most wind turbine manufacturers have made progress in lowering the noise of turbines by adding insulation around the generator
and building specially profiled blades that reduce noise and, wind turbine needs regular maintenance to remain efficient and provide you with regular energy
Economic impacts
Wind parks bring economic development to the rural communities that host them.
Developing our nation's wind energy resources creates demands for turbines and turbine components, which stimulates the manufacturing sector.
Wind energy helps to stabilize wholesale electricity costs, which is good for both consumers and for businesses
Wind energy benefits the economy in three ways:
Drawbacks
The main disadvantage of wind energy is that wind can never be predicted. In areas where large amount of wind is needed or winds strength is too low to support wind
turbine, there solar or geothermal energy could prove to be great alternatives
Potential Impacts
Harnessing power from the wind is one of the cleanest and most sustainable ways to generate electricity as it produces no toxic pollution or global warming emissions. Wind
is also abundant, inexhaustible, and affordable, which makes it a viable and large-scale alternative to fossil fuels
Environmental Impacts
Compared to the environmental impact of traditional energy sources, the environmental impact of (onshore) wind power is
relatively minor, slightly higher than the environmental impact of hydro power on a life-cycle basis. Unlike electricity derived from
basis.
fossil fuel and nuclear power plants, wind power consumes no fuel and, unlike fossil fuel power plants, emits no air pollution in
operation.[2]
