Renewable energy resources provide a large share of the total energy consumption of many developing countries. Evaluation of these resources has not been made in many countries and in many cases, data necessary to estimate the resource availability is also not easily available. However, for the profitable and sustained exploitation of these resources, a knowledge of their availability should be known. This article presents a review of the current energy use of Laos, a country in South East Asia, and its renewable energy resource potential. Renewable energy resources, such as solar, biomass, wind, and hydro resources have been estimated and presented.
