Electromagnets do not produce energy at all. They require an electric current to make them work so they are consumers of energy.
Renewable means wind or sunshine, which keep on coming even if we use them to produce energy. So a TV is non-renewable.
Renewable energy sources use various non petroleum, non wood, non peat, non nuclear sources for fuel energy, typically to produce electricity. Petroleum, wood, peat, and nuclear energy are non renewable sources because they can be depleted faster than they can be replaced. The main way these energy sources are alike is they are all used to produce electricity.
Renewable energy can't run out. Non-renewable energy WILL run out. Renewable energy is produced at a constant rate, non-renewable is not. Renewable energy is free when the generator is built, non-renewable is not. Renewable energy does not cause pollution (with the exception of biofuels), non-renewable energy does.
non renewable energy
Pens are non-renewable. Renewable things are sunlight, wind, water power etc.
Burning produces thermal energy
renewable source of energy can be regenerated but non-renewable source of energy can not be regenerated.
Energy that is renewable.
Renewable
Non-renewable energy source means that the source will eventually run out and is not renewable.
Coal is a non-renewable resource.
It is A renewable source of energy.
