• Increased cycle efficiency is the key to the cleaner use of coal for generating electricity. As efficiency increases, less coal is burned, and thus, less CO₂ is produced per megawatt of electricity. Improving efficiency will require increasing the maximum steam temperature and thus will require improved materials and components
