Since last decade Pakistan had been unfortunately stuck in massive energy crisis and as the population grows, demand increases and energy crises become worse.
The largest generator capacity of a single installed onshore wind turbine reached 7. The power available from the wind is a function of the cube of the wind speed, so as wind speed increases, power output increases up to the maximum output for the particular turbine.
Typically full load hours of wind turbines vary between 16 and 57 percent annually, but might be higher in particularly favorable offshore sites.
Wind energy was the leading source of new capacity in Europe, the US and Canada, and the second largest in China. Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand, assuming all practical barriers needed were overcome.
This would require wind turbines to be installed over large areas, particularly in areas of higher wind resources, such as offshore. There are many forms of water energy: Historically hydroelectric power came from constructing large hydroelectric dams and reservoirs, which are still popular in third world countries.
Small hydro systems are hydroelectric power installations that typically produce up to 50 MW of power. They are often used on small rivers or as a low impact development on larger rivers. China is the largest producer of hydroelectricity in the world and has more than 45, small hydro installations.
This style of generation may still produce a large amount of electricity, such as the Chief Joseph Dam on the Columbia river in the United States. Hydropower is produced in countries, with the Asia-Pacific region generating 32 percent of global hydropower in For countries having the largest percentage of electricity from renewables, the top 50 are primarily hydroelectric.
China is the largest hydroelectricity producer, with terawatt-hours of production inrepresenting around 17 percent of domestic electricity use.
There are now three hydroelectricity stations larger than 10 GW: A demonstration project operated by the Ocean Renewable Power Company on the coast of Maineand connected to the grid, harnesses tidal power from the Bay of Fundylocation of world's highest tidal flow.
Ocean thermal energy conversionwhich uses the temperature difference between cooler deep and warmer surface waters, has currently no economic feasibility. Solar energy Main article: Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
Active solar technologies encompass solar thermal energyusing solar collectors for heating, and solar powerconverting sunlight into electricity either directly using photovoltaics PVor indirectly using concentrated solar power CSP.
A photovoltaic system converts light into electrical direct current DC by taking advantage of the photoelectric effect. Commercial concentrated solar power plants were first developed in the s.
CSP-Stirling has by far the highest efficiency among all solar energy technologies. Inthe International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits.
It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainabilityreduce pollution, lower the costs of mitigating climate changeand keep fossil fuel prices lower than otherwise.
These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared".
Thermal energy is the energy that determines the temperature of matter.Renewable energy resources can prove vital in the electrification of remote areas in the provinces of Balochistan and Sindh, in particular, and in other areas, in general.
The government must also actively promote energy efficiency and conservation.5/5(2).

The Republic of the Marshall Islands will be closer to its goals of greener, more efficient and more reliable energy, following the approval by the World Bank’s Board of Executive Directors of US$34 million for the Sustainable Energy Development Project.
The National Renewable Energy Laboratory (NREL) mapping of Direct Solar Radiation in Pakistan shows highest values in southwest Pakistan, gradually decreasing to the north and northeast of the country with minimum in the Himalayan Mountains.
As the UK strives to reach its target of deriving 10% of its electricity from renewable sources by renewable and reusable energy is a hot topic from the classroom to parliament.
