Last week there was a 45 degree heat wave in Sydney.
Gaiasdream for the first time ever hat an electronics problem as that is in, we almost run out of electricity despite it was a nice sunny day for the solar panels.
The cause was because it was sooo hot the fridge could not cope and was running continuously for almost 24 hours on top of our normal electricity usage.
This illustrates on a small scale what happens in the normal electricity net, with every ones fridges and air-conditioners running.
Lesson learnt for me and every one else, change the settings on your fridge on really hot days and reduce electricity usage as much as possible.
In the end of the day the energy needs to come from some where.
