There’s been an energy shortage recently both in the UK and China, at the current stage, it is still a temporary incident but we must monitor it well, for there’s a possibility to go into crisis.
The shortage of the UK is caused by the shortage of heavy truck drivers after Brexit, they are trying to refill it from East Europe and in the short term use army to take over. Even though there are many immigrants from Hong Kong, they are from medicine, education and finance, and have no heavy truck driving license, so they could not help. But with the help of mobile apps, oil stations are still in good order, and the problem can be solved soon.
In China, the scope is bigger and more structural, large areas have to cut off supply of electricity without prior notice. There is a shortage in production and now afraid having more serious effect on major cities. The problem will take a longer time to solve.
