Here's a heat wave worth looking at!
Air conditioning uses over 30% of the peak electricity on a hot day in California - and by time-shifting the cooling using stored ice, in some buildings the peak can be completely ironed out.
What's more, the air conditioning capacity needed is reduced, as it's working for longer to produce the same amount of cooling.
As air conditioning becomes more prevalent in UK and Europe, this is becoming an increasingly relevant way to avoid peaks in summer.
Conversely, in winter, if we are to use electricity for heating, it will become worthwhile to store hot water or even steam to reduce peak consumption.
