Thailand is among the leading countries pursuing the development of alternative sources of energy. The country's 15-year plan to lift alternative and renewable energy's share of total energy production from 6% today to 20% by 2022 has been implemented with great success and spearheaded fast and expansive growth of the alternative energy sector. In 2010, for example, requests for investing in Thailand's renewable energy projects increased 300%, as compared to the already impressive numbers of the previous years.
