与此同时，掣波脉冲放大已经把脉冲的峰值功率提高到兆兆瓦水平。

Meanwhile, the chirped pulse amplification technique has boosted the peak power of the pulse to the terawatt level.

但这数据与全球电力总消耗的16兆兆瓦特相比可就算是小巫见大巫了，互联网消耗的电力最多只占全球电力消耗的2%。

But it's a small number compared with global energy use across all sectors. That figure is 16 terawatts, so the Internet is responsible for less than 2 per cent of the energy used by humanity.

国际能源机构估计，每年IT和消费类电子产品的能源消耗，正在按到2020年增加一倍和到2030年增加两倍的速度增长，将达到1,700兆兆瓦小时。

The IEA estimates that the yearly energy consumed from IT and consumer electronics is on pace to double by 2020 and triple by 2030 to 1,700 terawatt-hours.
