The Expert answers:
Coal, gas and oil are fossil fuels and are non-renewable (at least not for a couple hundred million years)
Coal is the most abundant fossil fuel. Most of it exists in the USA, China and Russia.
Nuclear fission is non-renewable because Uranium is non-renewable (unless one has a supernova handy)
The universe has the same amount of energy now as when it began. According to physics, neither matter nor energy can ever be created nor destroyed. One can become the other, however. (This is how nuclear energy works).

Charles asks…
What are the social and moral implications of the continuing development of renewable energy?
I’m doing Engineering and I am really stuck. I have to include EEC and world targets, whatever they are. Please help me, someone?
Thanks
The Expert answers:
How about this: start by identifying some renewable energy sources. Get some ideas and thoughts flowing by creating a flow chart of each stage of the supply chain from source to delivery and try and identify a social and moral aspects at each stage of the chain. Then think about some non-renewable energy sources (which they all are eventually – ha – just some are gonna run out before the new deposits are down) and compare and contrast. Good Luck
