能源使用是我們這個時代的關鍵議題之一。 人們傳統上依賴化石燃料，包括石油、煤炭和天然氣。 然而，人們越來越擔心這些能源造成的污染。 此外，這些能源是不可再生的。 也就是說，它們可以用完。 世界各國正在探索使用太陽能等再生能源的方法。 能源研究傳統能源的角色和替代能源的開發。
Energy use is one of the key issues of our time. People have traditionally relied on fossil fuels, including oil, coal, and natural gas. There are growing concerns, though, about the pollution caused by these energy resources. In addition, these sources of energy are nonrenewable. That is, they can be used up. Countries around the world are exploring ways to use renewable sources of energy, such as solar power. Energy Resources examines the role of traditional sources of energy and the development of alternative energy resources.
