This week hundreds of Borneo tribes men armed with blowpipes blockaded roads in the Malaysian state of Sarawak to protest against companies they accuse of destroying their rainforests to grow oil palms for “green” biofuel.

Marine turbines are a great hope for renewable green power. One of the most promising marine energy technologies is the tidal turbine, which was advocated in Manchester by Peter Fraenkel of Marine Current Turbines (MCT). These devices act like underwater windmills, with blades that rotate as the tide flows through them. Tidal turbines create large amounts of power in those countries with very fast-flowing tidal streams – such as the UK and Canada – and in the future similar devices could be Read more [...]
