c) Jimmy Carter

In a pioneering environmental move, Jimmy Carter installed solar panels on the White House in 1979. This act was more than symbolic; it was a statement of Carter’s commitment to renewable energy and environmental stewardship during a time of energy crises. His decision reflected a forward-thinking approach to resource conservation and an early acknowledgment of the potential of solar power. Although the panels were later removed, Carter’s initiative set a precedent for future administrations and highlighted the importance of environmental consciousness at the highest levels of government.
