South East Asia is widely recognised as a leading location for direct investment, with an existing strong and diverse industry base. One of the most exciting areas of opportunity in the region is Renewable Energy (RE). South East Asia is a huge potential market for RE. In this Paper, we examine the potential for Renewable Energy in Indonesia, Philippines, Malaysia, Singapore, Thailand and Vietnam. In addition to the 6 countries which we have examined in this Paper, further huge opportunities will likely exist in other ASEAN territories, such as Myanmar, Cambodia and Laos.
