Electricity

Electricity is the most versatile kind of energy. It plays an important part in almost every technology. Electrical energy can be produced directly by

• Photovoltaics
• Dynamo
• Thermocouple

Electricity can be directly used to produce

• heat
• light
• movement of machine parts.

Electrical energy can be directly stored in capacitors and inductors, but only in very small amounts. Large amounts can be stored indirectly in other energy forms.
