What is power and energy technology?

Energy technology is an interdisciplinary engineering science having to do with the efficient, safe, environmentally friendly and economical extraction, conversion, transportation, storage and use of energy, targeted towards yielding high efficiency whilst skirting side effects on humans, nature and the environment.

Also know, what is the difference between the energy and the power?

Power is the capacity of energy, which is being used. While energy is 'joules', power is 'joules per second'. Well, in another words Power is 'watt' and Energy is 'watt-hour'. Another difference is that energy can be stored whereas power cannot be stored.

Is there a difference between energy and power?

A watt equals a joule per second. If a smart phone uses five joules of energy every second, then the power of the phone is five joules per second, or five watts. The animation above demonstrates the difference between energy and power.
