How much power is 4 MW?

4 megawatts - heaps

The megawatt is equal to one million watts. Many events or machines produce or sustain the conversion of energy on this scale. For example: lightning strikes, large electric motors, naval craft (such as aircraft carriers and submarines), engineering hardware, and some scientific research equipment, such as supercolliders and large lasers. A large residential or commercial building may consume several megawatts in electric power and heat.
