Bar length represents energy. Equal energy does not imply the same temperature, power or usefulness.

A little perspective

1 megawatt-hour is about 3.6 times the energy of a lightning energy model.

Measurements, assumptions & sources +

1 megawatt-hour

Energy: 3.6 GJ; definition.

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • The energy of a lightning energy model: This is an illustrative comparison value, not a claim that every example is the same.

Energy is an amount; power describes the rate of energy transfer or use.
