Clean CoalClean coal is a term used for any technology that reduces the carbon emissions of coal combustion. Green and clean fuels are crucial to energy security. National Geographic Society is a 501 (c)(3) organization. While some think coal will run out as early as 2052, and others think it can last a few more centuries, one thing is certainly clear: there is only so much coal on earth and no matter how many more pockets of it we discover, well eventually run out of coal. Scrubbers and filters can also capture the CO2 before it is able to get into the atmosphere. Follow me as I explore and expose the little-known electrical strategies and tactics that will change the way you think about electrical ideas in your company.
