Coal-based power has become a key element of India's energy sector. As the country's energy and power needs continue to grow, the role of coal will remain undiminished for at least the next few decades. Yet, there are a number of challenges facing the coal-power sector, and there are several constraints that will affect its trajectory. There is now a broad and evolving array of technology options for the coal power generation, unlike in the past when subcritical pulverized coal combustion was the dominant technology of choice.

The incoming Obama Administration and the 111th Congress face enormous challenges and opportunities in tackling the pressing security, economic, and environmental problems posed by the energy sector in the United States and worldwide. Improving the technologies of energy supply and end-use is a prerequisite for surmounting these challenges in a timely and cost-effective way.
