The fast-evolving commercial and industrial sectors, together with consistent population growth, have constantly escalated Thailand's energy demand. Our nation's annual energy consumption has soared at a percentage of 13 during the past decade, and tends to retain a similar pace continually. While energy demand has risen sharply, domestic sources of supply are limited, thus forcing a significant reliance on imports. The proportion of imported energy to total energy demand exceeds 60 percent each year, costing over 155,000 million Baht. In addition, investments in energy exploration and development will add considerably to the country's financial burden and are likely to start a long series of decline in priceless natural resources and environment.
