Depends on the heater. You can have Electric heaters, propane heaters only to mention two.
Most washing machines use electricity as the primary source of energy for operation. Some newer models may also incorporate energy-saving features or options for using hot water from a water heater.
A common source of energy used to heat up water is thermal energy. This can be generated through various means such as electricity, gas, or solar energy, which then heats the water in a water heater or boiler for domestic or industrial use.
Potential to kinetic. Before you turn the shower on, the water is above the ground, waiting in the pipes. Once you open the valve it falls, converting that potential energy into kinetic energy.
An electric clock typically uses electrical energy, which is converted into mechanical energy to power the movement of the clock hands. The electrical energy is provided by a power source such as a battery or a wall outlet.
Geothermal energy is the energy source that transforms heat energy from the Earth into mechanical and electrical energy. This process involves harnessing heat from beneath the Earth's surface to generate power through the use of geothermal power plants.

Nuclear energy sometime uses uranium for its energy source.
Electrical (alternating current)

any source
Geothermal, because it is one of the easiest to use and install.
Glucose is the only energy source that the brain can use.
Carbohydrates
