What is Renewable energy?
Useful energy that is
replenished naturally on
human time scale.
Some examples of
renewable energy
include:
•Wind energy
•Biomass energy
•Solar energy etc
Renewable resources
Resources that are replaced by nature as fast as used by
human beings.
Examples:
•Wind
•Water
•Heat from core
•Sunlight
•biofuels
Types of renewable energy
Wind energy
Solar energy
Power of wind is used to
generate electricity or it
is converted into useful
energy.
Use of solar cells to generate
useful energy from light..
Hydropower energy
Energy from waves and tides
of water is used to generate
electricity.
Geothermal energy
Heat from core of earth is
used to convert water into
steam to run turbines.
Biomass energy
.
Replaceable organic
components are used for
useful energy generation.
Renewable energy in Pakistan
Expanding renewable energy can
help Pakistan to save 5 billion
dollars.
According to world bank,
only 0.071 percent of
Country area can be used to
meet the need of whole
country electricity demand
by ussing photovoltic cells
Pakistan has several wind
corridors having average
speed of 7.87 m/s.
Hydropower has share of 13 percent
with minor involvement of solar and
wind energy
Approximately,50,000 tonnes of solid
waste , 2,25,000 tonnes of crop
residue and over 1 million tonnes of
Animal manure are produced daily.
The potential capacity of wind energy is
estimated at 122.6 GW per year,double
than current production of whole Country
electricity generation projects.

Advantages
Cheap and reliable energy
Eco friendly
It causes negligible environmental
pollution as compared to energy
produced from conventional
sourcesit has low or zero carbon
emission..
Recycling
Renewable energy helps in
recycling of wastes hence
leading to less carbon emission
in atmosphere and organic
wastes in landfills..
It helps in saving money in
long term.It helps in saving
maintainance as well as
operating costs.
Stabailized energy prices
As cost of renewable energy
only depends upon initial costs
of installment,It will result in
stabilized prices across the
globe.
