Choo the best answer（根据短文内容，选择最恰当的答案）：
Most of the energy we u for heating, lighting, transportation and manufacturing（制造业 ）comes from fossil fuels. The are carbon-bad fuels from oil, coal and natural gas. When we burn the fuels we relea heat which provides the energy.
There are three main disadvantages to using the fuels. Firstly, they are causing climate problems becau of the Greenhou Effect. When we burn fossil fuels they produce carbon dioxide which caus global warming. Secondly, when we have ud up all our coal, oil and natural gas, we will have nothing left to burn. Thirdly, they are not very efficient. The internal combustion engine（内燃机 ）that we u in most cars, trucks and bus, for example, is only about 14％ efficient（效率的 ）.

Scientists are working on another fuel—hydrogen. There are a couple of advantages to using hydrogen as a fuel. Firstly, becau two-thirds of the earth's surface is water and water is made of hydrogen and oxygen. There is an almost unlimited supply of hydrogen. Secondly, burning hydrogen does not cau global warming. Thirdly, it is much more efficient than carbon-bad fuels.
Unfortunately there are problems with hydrogen at the prent time: there is the problem of parating it from water cheaply, and there is the difficulty of storing it. It can be stored under pressure but high pressure tanks are far from safe. It can also be stored as a liquid but only at extremely low temperatures. It ems likely, therefore, that there will have to be a completely new technology before hydrogen replaces fossil fuels. Solving the problems is an urgent matter. Although China, India and Australia have huge amounts of cheap coal, and there are still large oil and gas rerves（储量 ）elwhere, the effects on the planet's climate will be bad if they are ud.
