wastes a lot of energy

Peak Demand vs
Energy Usage
Eg we want our kettle to boil the water fast, so
we have a 2 kW kettle which boils the water in 2
minutes rather than a 1 kW kettle which boils the
water in 4 minutes
We need to build bigger power
stations which run for shorter
periods of time
An inherent flaw in our thinking?

of pumped storage
Hydro-Electric Dams

History Battery inventions
What is it?
Temporary or permanent
storage of energy
We burnt or produced too
much and we want to save
the waste for later
Accumulator A Rechargeable Battery
The Public
Tesla & Elon Musk

Everyone is now talking about
batteries for homes & businesses
What is a battery for?
Energy Storage
Maybe supporting peak
demand requirements?
Eg Small users can remove
themselves from the grid or become
producers with very short notice

Demand Response
Heat Storage
Maintenance and Charging
Needs a separate discussion
