I’ve been wondering, for 1 kW/h of electricity, what do we have to give in exchange? And what does it mean to our daily lives? According to the statistics from the United Nations, in Africa, some must leave their homes every seven days, to go line-up some place 30km away, just for 1 kW/h of electricity in a single battery. However, this tiny bit may provide one family with the electricity to power two light bulbs for a whole week.
