We had some really great threads last year, with the following four nominated for the Thread of the Year award in this January's Environment Site Awards ceremony.
Fossil Fuels and Peak Oil ForumRestore human legs as a means of travel. Pedestrians rely on food for fuel and need no special parking facilities - Lewis Mumford
The weakening dollar is increasing the chances of a cut in output by oil producers' group Opec at its next meeting later this month.
Ministers opted for the cut - which came into effect in November - to help stabilise prices after they fell from a peak of $78.40 a barrel in July to below $60 in October.
Oil prices fell in light pre-holiday trading on Friday, but held above $62 a barrel as brokers weighed slower economic growth and expectations of a mild winter against the Organisation of the Petroleum Exporting Countries' (Opec) determination to tighten up worldwide supplies.
