Hello,
From time to time I am desperate about finding reliable or understandable or documented data about fuels and raw materials. I google then for a few hours and get a few data. For example, I recently discovered www.ecn.nl/phyllis that is rather interresting but far from totally satisfactory, for fuels. For raw materials, it is even more difficult.
Therefore my obvious question for today:
where can you find some useful data on fuels and raw materials ?
what are your best references ?
Thnaks a lot.
