加利福尼亚最近的能源短缺突出了经济日趋活跃的世界能源供应不足。煤的储存终究会被耗光；就算它是无穷无尽的，燃煤释放CO2造成的全球气候变暖也让人们意识到煤并非理想能源。因此不释放CO2的能源日益重要，其中最有吸引力的是核聚变，但通过这种途径获取能量已证明很有难度 Recent energy shortages in California highlight the under-energy supply in the increasingly dynamic world economy. After all, the storage of coal is depleted; even if it is inexhaustible, the global warming caused by the release of CO2 from coal combustion also makes people aware that coal is not an ideal source of energy. Therefore, the energy that does not release CO2 is increasingly important, of which nuclear fusion is the most attractive, but obtaining energy through this route has proved very difficult
