It warns that hot batteries lose power faster, even when not being used.

它警，使不使用，高温电池也会更快地去电力。

It conducts it electricity and heat efficiently and has been slowly realizing its potential as a game-changer.

它有效地传导电力和热量，并逐渐显现其改变游戏规则的潜力。

Wind turbines and solar panels provide power only intermittently; for now, dirtier power plants are needed as back up.

风力涡轮机和太阳能电池板只能间歇性地提供电力；目前，需要更脏的发电厂作为后备。

Such materials can transport electricity without dissipation.

这些材料能够无耗地传输电力。

So they decide, we need more transmission to make the power flow more efficiently.

所以他们决定，我们需要更多的传输设施来让电力更高效地流动。

In principle, a connected electrical energy network with power lines crisscrossing the globe would enable us to transport power from where it's generated to where it's needed.

则上，一个由纵横交错的输电线路构成的全球互联电力网络，将使我们能够将电力从发电地输送到需求地。

And in part, it was because the United States had surpassed the United Kingdom in the Second Industrial Revolution, first harnessing the power of electricity more broadly.

部分因是美国在第二次工业革命中超越了英国，率先更广泛地利用电力。

And he's giving every indication that he is determined to maximize day-to-day suffering — and economic damage — by denying heat and electricity to Ukraine and its allies in Europe.

他释放出的种种迹象表明，他决心通过拒绝向乌克兰及其欧洲盟友提供暖气和电力，最大限度地增加他们每天的痛苦和经济。

The next design principle is that because SoCs are used in smartphones, which operate on a battery, there's a huge focus on having the SoC consume as little power as possible.

下一个设计则是， 由于系统级芯片用于智能手机，而智能手机依靠电池供电， 因此需要系统级芯片尽可能地节省电力。

Other improvements have focused on making sure that as much of the chip as possible is doing useful work at any given moment since idle circuitry wastes power to no purpose.

其他改进则集中在确保芯片尽可能多的部分在任意时刻都在进行有用的工作，因为闲置的电路会无谓地浪费电力。

It might not have smoke coming out of the back of it, but that smoke is coming out of a factory hundreds or thousands of kilometres away, as that is where the electricity was produced.

它可能不会从车尾冒出烟雾，但那些烟雾却来自数百甚至数千公里之外的工厂，因为那里正是电力的生产地。

And if we could figure out how to make this stuff, it would be incredibly useful: It’s thought that metallic hydrogen would be a superconductor at room temperature, meaning that it would be perfectly conduct electricity.

如果我们能够弄清楚如何制造这种物质，它将非常有用：据认为金属氢在室温下会是超导体， 这意味着它可以完美地传导电力。

While electric forms of transportation such as electric cars, bikes and railways may make more efficient use of electricity and reduce vehicle emissions, their overall impact on reducing carbon dioxide depends on how clean the source of electricity is.

尽管诸如电动汽车、自行车和火车等电动交通工具可以更有效地使用电力，减少车辆废气排放，然而它们对减少二氧化碳的总体性影响仍取决于电力来源有多干净。
