But the overall energy availability in the brain is thought to be constant.

不过，我们一般认为大脑的整体能量可用性是恒定的。

We will keep overall grain output above 650 million metric tons, and enhance our overall energy production capacity.

粮食综合生产能力保持在1。3万亿斤以上，提高能源综合生产能力。

India depends on coal for 75 percent of its electricity needs and for 55 percent of its overall energy needs.

印度75%的电力需求和55%的总能源需求依赖煤炭。

But the most telling metric is likely the role of renewables in a country’s overall energy mix.

但最有说服力的指标可能是可再生能源在一个国家整体能源结构中的作用。

Well, when the body is at rest, we know that the brain use up a startling 20% to 25% of the body's overall energy.

众所周知，当身体处于休息状态时，大脑消耗的能量在身体总能量中的占比非常惊人，高达 20%~25% 之多。

The university can invest in improving the overall energy efficiency of the buildings by improving insulation and reducing heat loss through windows and walls.

大学可以花钱投资改善教学楼的整体效能，通过改善隔温以及减少窗户和墙的热量损失。

Because in relation to the brain's huge overall energy usage, which is devoted to a multitude of tasks, the energy required just to think harder is actually comparatively tiny.

因为和大脑进行各种各样任务所消耗的大量能量相比，深度思考消耗的能量其实是很少的。

The final potential cause is an increase in snacking and eating out over recent decades — both in terms of how often they happen and how much they contribute to our overall energy intake.

最后，无论是从发生的频率还是从对我们整体能量摄入的贡献程度来看，还有一个潜在原因是近几十年来零食和外出就餐都增加了。

We need to plan for these transitions— either to the new technologies or to entirely new economic opportunities— at the same time as we're inventing the new tools to complete the overall energy transition.

我们需要为这些转型做好准备，不论是新技术还是全新的经济机会 —— 同时我们还要发明新工具来完成整体能源转型。

I was heavily inspired by her work ethic, and her overall energy, but also just the way that she turned a look, especially when it's like 5: 00 AM. It's amazing.

我深受她的职业道德和她的整体能量的启发，还有她转身的方式， 尤其是在凌晨 5: 00 的时候。 太奇妙了。
