power multiplied by time
Electric energy
The motor is electric, the hot water is typically heated by gas or electric.
Electric energy (stored beforehand) --> Mechanical energy (used)(causing fan to spin; producing wind)
A thermocouple does this, but a turbine does also.
Heat energy could be used to produce steam. The steam could be used to spin turbines and thus producing mechanical energy (to be used to move e.g submarines and/or ice breakers). The mechanical energy could move electric generators to produce electric energy. Another option is to use heat energy to produce hydrogen. Hydrogen could be used to produce electric energy (through fuel cells) or to produce mechanical energy (in cars and buses and other vehicles)
Electric companies calculate the amount of electric energy by using special consumption meters.
Electric companies calculate the amount of electric energy by using special consumption meters.
They generate electrical energy from nuclear energy, and then distribute it through wires to your house, where it can be used to run your lights, your TV, and your electric can-opener.
They usually just measure current used and assume a known voltage.
The quantity you pay for is energy. It's calculated as (power) x (time).

Hydroelectric energy is electric energy produced with hydro(water). How the electricity is produced makes no difference on how it is used. Electricity is used for lights, electric motors, electric heat etc.
The benefits of using solar electrical power over conventional electric power is that it is renewable, it can save money on conventional electrical bills, and if used in large enough quantities it can even eliminate the need for energy from energy companies.
