The modern day sustainability movement in the U.S. actually began as early as the 1970s with the creation of the Environmental Protection Agency and the enactment of notable legislation by the U.S. government.
In the early years, much of the EPA’s focus was on reducing pollution and improving air quality, working primarily within the power generation segment. Since 1990, the greenhouse gas emissions from electric power have decreased roughly 21%, thanks in part to greener energy sources and more efficient end-user products.
