The electric kettle averaged around 1200 watts and took 125 seconds to boil the water, which translates to 0.04 kilowatt-hours (kWh) of electricity consumed.

How much energy does it take to boil water?

So in water it takes 1200 joule’s to raise a Kg of water by 1 degree K or in degrees C. If this takes 1 min to boil the power required to boil the water equals 96kilo joules/60 seconds =1600 watts or 1.6 kilo watts.

Does it take a lot of energy to boil water?

Explanation: In order to cause water to increase in temperature, the energy being put into the water first needs to break hydrogen bonds between the water molecules. Hydrogen bonding in water is significant, so it takes a significant amount of energy to overcome them.
