Electricity is a form of energy which mankind use to power machines and electrical devices. It arrives at our homes and workplaces through wires from the places where it is made. It is used by elecrictical lamps for producing light, electrical heater to produce heat, etc. Electricity is generated in the place called power stations. The sources of energy used to make electricity are either conventional or renewable. Electricity generated by burning of fossil fuels such as coal, petroleum, natural
yield like lower energy cost than any other method. Natural sources of renewable energy are 1. Solar 2. Wind 3. Geothermal energy 4. Biomass 5. Ocean 6. Hydropower 1. Solar energy- Sun is the main source of solar energy. Most renewable energy comes either directly or indirectly from the sun. Using sun radiation, we use solar cooker for cooking food, solar heater for heating water naturally, using solar panels we used to store and generate electricity and variety of commercial and industrial
process is [Teoh and Chung, 2009, Alcheikhhamdon et al., 2015](4): 1. Low permeate flow rate. 2. Membrane fouling and membrane pore wetting 3. Long term performance. 4. Uncertain economics and energy costs. 5. Mass transfer resistance due to trapped air in the membrane which reduces permeates flux. 6. Low membrane lifetime. 1.4 Application of membrane distillation According to [El-Bourawi et al., 2006, Zhang, 2001] membrane distillation has been applied for: 1. Large range of desalination and
