This book highlights the present scenario of energy demand and power generation technologies in tropical countries. The tropics are well known to receive direct sunlight. Furthermore, different than four-season countries, tropical countries have a continuous summer-like season, and therefore, they are rich in clean energy sources, like solar and biomass. Home to 40% of the world?s population, the demand for energy in these countries keeps increasing. With the present serious global concern on the environment, the choice of power generation is no doubt the cleanest possible resources. This book delves into the opportunity that various tropical countries have in pursuing environmentally friendly power generation systems.
