Peak Demand vsEnergy Usage

Eg we want our kettle to boil the water fast, sowe have a 2 kW kettle which boils the water in 2minutes rather than a 1 kW kettle which boils the

water in 4 minutes

We need to build bigger powerstations which run for shorter

periods of time

An inherent flaw in our thinking?

What is it?

Temporary or permanentstorage of energy

We burnt or produced toomuch and we want to save

the waste for later

Everyone is now talking aboutbatteries for homes & businesses

What is a battery for?

Energy Storage

Maybe supporting peakdemand requirements?

Eg Small users can removethemselves from the grid or become

producers with very short notice
