Engineering work has begun at a coal-fired power station on the banks of the Thames in England, UK that could turn it into the world's largest biomass plant with almost no carbon emissions. The owner of the Tilbury power station, previously scheduled for shut down in 2015 under new EU environmental regulations, says it hopes to produce up to 750 megawatts of green power by winter. Last week it was reported that the approval of new rules for air pollution, water pollution, and waste disposal in the US could result in the retirement of between 35 and 70 gigawatts (GW) of coal-fired power generation throughout that country.

Japan dispelled fears among many diamond traders that after the earthquake and following tsunami that hit the country on March 11, it will lose its taste for diamonds. In April, Japan imported $95.7 million worth of polished diamonds, increasing by 80.1% year over year, and by 56.8% from March. The increase in imports proved once again, as predicted, that when a country is hard hit, it express its feelings more openly, often with diamonds. This was the case in after the September 11 terrorist attacks, and again in the recent sub-prime economic crisis.

One of the contributors to the low gold prices of the 1970s was substantial hedging of forward output by mining companies, either as corporate policy, or at the insistence of lending institutions who wished to protect their positions should the price fall further. Conversely, a contributor to the rise in gold prices over the past few years has been very substantial de-hedging by, in particular, the gold majors, which has effectively soaked up some gold demand, as belief grew that the run up in the gold price had much further to go.
