No. The term SOURCE means that it is a supply of electrical energy, and a light bulb does not supply electricity, it uses it. A battery, generator, fuel cell, or solar cell would be a source.
Uranium (or plutonium) is a source of energy (nuclear fuel) in nuclear power plants.
The mitochondria in a cell convert food cells into energy. The cell uses that energy to kickstart necessary reactions.
Nuclear- the largest no fossil fuel source in the world Oil- may run out in the next 100 years Hydroelectricity- uses running water solar power-uses energy directly from the sun
Electricity.
- energy source - radiation source - tracer - fuel for nuclear reactors - explosive for nuclear bombs
A steam engine uses a hydrocarbon based fuel source. The combustion of the fuel releases the chemical energy in the bonds in the form of thermal energy.
Energy cannot be created, not even in the Sun. If saying that the Sun is a "source" of energy gives you this impression... well, it doesn't actually create the energy. It only converts energy - from the potential energy (nuclear energy) available in the hydrogen-1, which is the fuel the Sun uses. Once it uses its fuel up, there will be no more. If anybody says the Sun is a "source" of energy, that simply means we get the energy from the Sun. This sort of statement doesn't analyze in more detail where the energy comes from.
When someone creates controllable hydrogen fusion you can say that. For now when people say cars are hydrogen powered what they mean is the car uses a hydrogen fuel cell, which is really a clever sort of battery, so hydrogen is more an energy storage option than energy source.
Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of energy.
When the cell uses energy
They are a car that uses gas as a source of energy.
