Estimates show that at least 10 terawatts (TW) of clean, economical electricity will be needed to maintain an adequate energy supply for the 21st century. To provide a modern lifestyle for everyone on the planet, the number increases to 50 TW.
Although the use of coal in the United States has declined, the worldwide consumption of coal continues to rise. Since emissions from coal-fired plants are a worldwide problem, cleaner and more efficient technologies developed to meet regulations in the United States are needed throughout the world.
