Lockdowns have been a controversial aspect of the COVID-19 pandemic. Yes, they undoubtedly save lives, but they also cause major ongoing economic issues – disrupting industries, causing job losses and associated financial pain. 新冠疫情期间的居家隔离饱受争议。毫无疑问,居家隔离能挽救生命,但也会造成重大经济问题,各行各业停摆,造成失业和相关经济损失。 But another thing lockdowns have done all over the world is decrease air pollution, and new research shows an interesting flow-on effect of this. 但居家隔离也有好处,全球的空气污染减少了,新的研究展示了这一现象的有趣影响。 The new study has looked at solar power in Delhi – one of the most polluted cities in the world – and has found that the reduction in air pollution has allowed significantly more sunlight to get through to solar panels in the city, increasing their output. 这项新研究观察了德里的太阳能,德里是全球污染最严重的城市之一。研究发现空气污染的减少大大增加了该市照射在太阳能电池板上的阳光,提高了电量输出。 "The increase that we saw is equivalent to the difference between what a photovoltaic (PV) installation in Houston would produce compared with one in Toronto," says first author Ian Marius Peters of Helmholtz-Institut Erlangen-Nürnberg for Renewable Energies in Germany. |
