- 5. Renewable Energy Renewable energyis generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat.
- 6. History Nearly allthe sources of energy were renewable till mid of 19th century The oldest renewable source of energy was biomass to fuel fire Second one harnessing the wind to drive the ship over water
- 7. History In the midof 19th century development of coal shifted the sources of energy By 1873, concerns of running out of coal prompted experiments with using solar energy
- 8. History Development ofsolar engines continued until the outbreak of World War I.
- 9. Introduction There are manydifferent sources of renewable energy These sources are listed below.

- 13. Wind energy • Movingair = wind • Energy that got from a wind is called wind energy • Wind turbines are used for getting energy
- 14. Wind Turbines • Turbineblades spin from the wind and make energy • Wind rotates the turbine blades which spins a shaft connected to a generator • The spinning of the shaft in the generator makes electricity
- 15. Wind energy Eachwind turbine can produce between 0.25 to 2 MW of electrical power. Wind farm needs to be located where there is a relatively high average wind speed. It requires 15km/hr speed of wind
- 16. Wind Turbine Power P= 1/2 x rho x A x Cp x V3 x Ng x Nb P = power in watts (746 watts = 1 hp) rho = air density (about 1.225 kg/m3 at sea level. A = rotor swept area, exposed to the wind (m2) Cp = Coefficient of performance V = wind speed in meters/sec Ng = generator efficiency Nb = gearbox/bearings efficiency.

- 19. Potential of windenergy in Pakistan The wind map developed by National Renewable Energy Laboratory has indicated a potential of 346,000 MW in Pakistan. In Sindh and Balochistan there is a potential of more than 50,000MW Total Area of Sindh suitable for wind farms = 9749 km2 Average Capacity Factor of this area in Sindh = 25%
- 20. Punjab has potentialof 1000MW First wind power generation plant of 50 MW was inaugurated in December 2012 and started full production in 2013.

- 32. Solar Energy Solarenergy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. Electricity can be produced directly from photovoltaic, PV, cells. (Photovoltaic literally means “light” and “electric.”
- 33. Solar energy The energyutilized from sun light is called solar energy There are two methods for harvesting solar energy Concentrating Solar thermal Plant(CSP) Photovoltaic plants(PV)
