Many environmental groups in the 1960s and 1970s battled against the use of nuclear power to produce electricity because they considered it a dangerous source of pollution to humans and their environment. This bumper sticker promoted the use of solar power as an alternative and safer method for providing the world’s energy needs.
During the gas shortages of the 1970s, American motorists were encouraged to reduce highway speed in order to cut fuel consumption and automobile emissions. The U. S. Environmental Protection Agency issued this red, white, and blue bumper sticker in the shape of a flag during the 1976 Bicentennial to promote patriotism and support for this unpopular idea.
