正如一辆汽车会被燃料过滤器堵塞一样：燃料（能源）不能迅速、顺利的传到它需要的地方，汽车不能快速有效的行驶。
Imagine a car that has a clogged fuel filter: thefuel (our energy) can’t get to where it needs to go quickly and smoothly, andthe car performs inefficiently and ineffectively.
风能确实可以弥补电网需要的20%的热储备，但是它绝不可能替代化石燃料。
Wind can indeed supplement a grid with this needed twenty percent spinning reserve, but it cannot come close to replacing fossil fuel.

甘蔗是唯一一种表现出可以让温室气体排放净减少的作物，因为它需要的化肥少于其他生物燃料作物。
Sugar cane was the only crop shown to have a favourable balance of greenhouse gas savings and emissions, because it requires less fertilizer than other biofuel crops.
当反应堆的核心铀和锆合金的燃料棒融化时，它需要2,200摄氏度的高温，同时释放大量辐射微粒。
This is when the uranium and the zircalloy fuel rods at the heart of the reactor melt. It occurs at temperatures above 2,200c, releasing highly radioactive particles.

伊卡洛斯飞船还没有最终确定它的核聚变燃料类型，但毫无疑问也需要携带大量的燃料。
Icarus has not made a final decision on the type of fuel to be used for its fusion engine, but it is almost certain it would require a substantial amount of propellant.
它需要更多的保养，消耗更多的燃料，起步慢，这是因为聪明依赖学习——一个渐进的过程——而不是本能。
It takes more upkeep, burns more fuel and is slow 6 the starting line because it depends on learning—a (an) 7 process—instead of instinct.
但2010TK 7可能不会被选为目标星体，因为它的行进偏离地球轨道平面的距离过大，使得抵达它需要耗费大量燃料。
TK7 is probably not the rock of choice, simply because it travels too far above and below the plane of Earth's orbit, which would require a lot of fuel to reach it.
燃料组件会被放置入，反应堆，还有核心会被运作大约一年，到18个月，在它再次燃烧，新的燃料需要加进去。
And then the fuel assemblies are placed into the reactor and the core is operated for about a year to eighteen months before it has to be re-fuelled and fresh fuel has to be put in.
就像一辆汽车，身体也需要燃料来保持它的运行。
Just like an automobile, a body needs clean fuel to keep it running well.
