Kenneth Deffeyes

Kenneth Deffeyes was an American geologist and petroleum expert known for his work on oil geology and peak oil theory—the idea that global oil production will eventually reach a maximum before declining. He analyzed oil reserves and production trends, warning that the world may face energy shortages as oil becomes harder to extract. Deffeyes contributed to understanding the importance of finite fossil fuel resources and the need for alternative energy strategies. His insights encouraged awareness of sustainability challenges linked to fossil fuel dependency, making him a significant voice in discussions about energy resources and environmental impact.
