청정에너지 시스템은 놀랄 만큼 다양하지만, 기술 발전 덕분으로 우리 손아귀에 들어와 있다. 목질계 에탄올, 수소연료전지, 차세대 핵발전, 태양광발전 태양전지, 이산화탄소 무배출 석탄 발전소 등이 전세계 각국의 전력 생산 방식을 보다 청정한 대체에너지원으로 전환시키고 있다.
Clean energy systems are incredibly diverse, yet technology has brought them within our grasp. Cellulosic ethanol, hydrogen fuel cells, next-generation nuclear power, photovoltaic solar cells, and near-zero-emissions coal plants will transform the way the economies of the world are powered to cleaner, alternative sources of energy.
