It is generally accepted that such conventional energy causes adverse impacts to the environments and global warming. Thus, a research study to use clean and renewable energy such as hydropower, wind power, and solar energy is vitally needed. Previous research reports on sustainable energy indicate that hydropower is the most feasible alternative energy in the South of Thailand and the Mini-Hydropower Plants (MHP) can be designed to be economical and environmentally friendly. The proper sites of MHP are available in hilly regions for the higher “Head,” and in moisture-filled tropical rainforests for the consistency of “Runoff”. Construction of large dams, due to many environmental impacts, is often faced with resistance from conservation groups, whereas the demand of diversion weirs for irrigation purpose and check dams for forest restoration is on the increase.
