There are no natural supplies of hydrogen. It always has to be removed from something, and the commonest source is water (H2O).
However, so far, there is no way to remove hydrogen from water that does not use more energy than the resulting hydrogen will produce. If a cheap way is discovered to separate water into Hydrogen and Oxygen then all our worries about global warming and peak oil will be over.
A.K.A its renewable
EDIT: correction: UV radiation naturally splits H2O molecules in the ocean, producing hydrogen and oxygen, which reacts with O2 in the air, forming ozone (O3). That is how the ozone layer formed. But yes, electrolysis of water to produce hydrogen is not very efficient at the moment.

Nuclear power is considered a non-renewable source of energy because it relies on uranium, which is a finite resource. Although nuclear power is a low-carbon energy source, the fuel source itself is not naturally replenished on a human timescale.
Nuclear power is considered non-renewable because it requires the mining of uranium, which is a finite resource. However, it is a low-carbon energy source that can help reduce greenhouse gas emissions.
no its a renewable source of energy
Nuclear fusion is not renewable. It requires hydrogen nuclei as an energy source, and once these have been used in fusion they are not naturally replenished. In fact, fusion power has a very high energy change, rendering it near impossible to reverse the process. A star, for example, is powered by nuclear fusion, and will eventually die out due to a lack of hydrogen.

Two typical examples are Oil and Solar power. There will come a time when the oil reserves will run out - making it a non-renewable source of power. Solar power on the other hand will be available as long as the sun continues to provide us with energy. The sun's energy is a continuing thermal 'cycle' turning hydrogen into helium, and back to hydrogen.
It is because it runs out

A non renewable source is something that is going to run out, like coal, oil and natural gas. A renewable source is something that is easy to get back quickly like solar power, wind, hydro and wave power. Most renewable sources needs the sun for their original power (except geothermal and tidal).
Renewable. Hydropower, also called hydroelectric power, is the technique of harnessing the power of water to create electricity. It is the world's leading source of renewable energy.
The turbines (mills) themselves are non-renewable but the wind the power source that is converted into useful work (usually electricity) is renewable.
Non-renewable energy source means that the source will eventually run out and is not renewable.
Renewable - unlimited source Non renewable - limited resource

Fuel cells are a manufactured item and are not renewable. The fuel that is used in the fuel cells can either be renewable (alcohol, methane from waste digestion,hydrogen from wind or solar conversion of water) or non-renewable (Hydrogen or methane from oil and gas production, alcohol from industrial processes)

Coal is a non-renewable resource.
