"Denis Allen Hayes " is an environmentalism/environmental activist and proponent of solar power. He rose to prominence in 1970 as the coordinator for the first Earth Day.

Hayes founded the Earth Day Network and expanded it to more than 180 nations. During the Presidency of Jimmy Carter/Carter Administration, Hayes became head of the Solar Energy Research Institute (now known as the National Renewable Energy Laboratory), but left this position when the Presidency of Ronald Reagan/Reagan Administration cut funding for the program. Since 1992, Hayes has been president of the Bullitt Foundation in Washington and continues to be a leader in environmental and energy policy.

Hayes has received the national Jefferson Awards for Public Service/Jefferson Awards Medal for Outstanding Public Service as well as many other awards. Time Magazine named him as "Hero of the Planet" in 1999.
