Methane...
While natural gas is a fossil fuel and not renewable, methane (the main component of natural gas) is recoverable from many industrial processes such as anaerobic digestion and by tapping into gas created by landfill sites, This secondary source is producible as it involves the chemical reduction of biological materials.
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)
Examples: oil, methane, coal.
Short answer: its renewable. Longer answer: Naturally formed pockets of methane will not renew themselves for thousands of years. However, methane can be made from biodegradable organic materials and those materials are renewable. So while it may be possible for us to use up all the naturally stored methane underground (though its not likely); we can always just make more by growing the organic materials needed to create it. So it depends on which source of methane you are talking about, naturally formed pockets of it are not renewable, but man made methane is renewable.
No.
Coal is the one we use the most of. Oil comes to mind. Nuclear energy is non-renewable. Methane is renewable, but not used much, nor easily renewable or environmentally freindly.
Psst! Come in close for this one. There is a secret here. Natural gas, that stuff the utility company pumps into your home, with which you heat the house, water, and cook. That is primarily methane, essentially the same stuff as the stink that comes from manure piles, and is locked in the sea bed. That stuff that the Greenies were complaining about a few years ago was adding to global warming (cow flatuence). In short, yes, methane is a very renewable resource.
