Technology has no good or evil; the key lies in how it is used.
技术没有善恶，关键在于如何使用。
我们不能在谈论能源转型时不谈论能源正义。
The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.
