AB  - Energy is an essential factor underpinning all elements of economy in the society. Its utilization greatly depends on the individual’s lifestyle and habitation. In rural areas, people use less electronic appliances compared to urban areas. However, the rapid development in technology and variety of applications have triggered the desire for more power in both rural and urban regions. To meet the energy demand, the world’s generation capacity has to keep growing. Renewable energy sources offer a better solution in quenching this demand.
