This icon for this design principle represents energy being stored in a container for use later on, while the proverb “make hay while the sun shines” reminds us that we have a limited time to catch and store energy. This is about investment.
Examples —Catch and store energy
Built—Thermal banks for ripening fruit, white paint, water tank - elevated
Biological—Seed saving, stored energy in leaves
Behavioural—changing our cooking habits - preserving food - surfing stores the energy from the sea as personal invigoration
