The world gets ┬╝ of its energy from renewable resources

Posted by Lindy on October 26, 2010


 

In spite of the economic crises of 2007-9, renewable energy sources continue to grow. Close to one quester of the energy supply generally and approaching 20% of the electricity comes from renewable resources. And all this is despite low oil prices and the poor performance of the Copenhagen  Summit in Dec 2009.

The prime movers are photovoltaic and wind power. China is in the lead, have added 37GW last year, of which 13,8 GW was wind power.

Germany is top of the PV market having added 3.8GW. Biomass power plants exist in over 50 countries around the world with Austria and Finland forging ahead with this.

One of the reasons for this growth, is that you can start small and cheap, unlike hugely expensive fossil fuel or nuclear power stations.

A new tidal wave machine

Posted by Lindy on September 6, 2008


Did you know that the UK is estimated to have 10% of the global extractable tidal resource? In other words, we have lots of places that are suitable!

And in Oxford they are trialling a brand new design, which costs only half as much as the standard models and requires even less maintenance.

More info found in the Guardian

Rubber ‘Snake’ Could Help Wave Power Get A Bite Of The Energy Market

Posted by Lindy on July 19, 2008


A neat way to use wave power – the wave squashes the fluid-filled tube which then forces the fluid forward which turns the turbine etc etc
