It’s a big year for alternative energy

These strange snake-like machines tap the power of surface wavesWhilst close to where I live the UK government is looking at proposals for the biggest tidal barrage in the world, elsewhere in Europe similarly ambitious projects are even closer to fruition. In Portugal the first ever commercial wavefarm is due to start any day now. A couple of huge wind turbines tapping into the vast wind energy of the North Sea have been a success and a farm of 200 of the 300ft high towers is now in planning, powering as much as a whole city. As I reported a few weeks ago, algae is looking more and more like the ultimate source for biofuels. Advances in nanotube growing and temperature controlled soldering are making big leaps in solar panel efficiency.

Even without the dual spectres of climate change and dwindling resources our future is likely to be wedded to many of these nascent technologies. When the Earth provides so much energy currently left untapped, it would be a shame not to use it. Economic centres in the future will be invariably tied to the amount of natural energy the environment nearby provides. It’s exciting to think that many of these technologies are reaching the point where they may soon be economically viable on large scale.
