Humanity really started messing with the global climate system during the Industrial Revolution when we began burning coal to meet rising energy demand from industrial manufacturing. Most industrial energy efficiency programs target large manufacturers, which represent about 10% of all manufacturers and account for half of the total industrial energy demand. But there still aren’t many programs out there to help small and medium-size manufacturers save energy through efficiency improvements, even though the group constitutes 90% of the manufacturing sector and accounts for the other half of industrial energy demand. Together, small, midsize and large manufacturers drive about a third of the harmful climate-warming emissions today.
