That depends on the type of calculator you are referring to. An abacus uses mechanical energy An electronic calculator uses electrical energy A brain doing mental arithmetic uses chemical energy
potential electrical energy
Electrical energy.
chemical energy
Solar calculators use a photovoltaic cell (solar cell) to convert light energy from the sun into electrical energy. The solar cell generates a direct current (DC) when sunlight hits it, which powers the calculator.
potential electrical energy
Electrical and mechanical
electrical
No the sun does not move. It takes in light energy from the sun which is converted to chemical and then to electrical energy (I think?)

It needs light, such as sun light.
The electrical energy is converted to heat.
