Renewable Energy Myth Busting

Guardian writer Chris Goodall set out yesterday to clarify 10 of the classic myths often cited against renewable energy. Many people believe solar power is too expensive to use, wind is not effective and marine energy cannot work.
Chris provides some interesting information, however some of the myths stem from an element of truth about the technologies which have in the past held them back. What is important is that people and companies are being financially driven to overcome the barriers and take these technologies to the next level where they are affordable.
Chris points to rapid innovation in the US which is expected to lead to thinner, more effective solar panels at a fraction of the cost of today. Unfortunately we are not yet there – everyone wants it to happen but mass market demand is still held back by high costs.
Spanish and German large scale solar power plants using long mirrors directing heat to a tube carrying liquid, in turn driving a steam turbine are described as being probably already financially competitive with coal on hot summer afternoons – although I’m not sure what comparison is over a year. The suggestion that Europe could get solar power from such plants located in the Sahara with a new long distance power line is moving into the realms of fantasy. There has been talk of a European super-grid for years, however we don’t seem to be able to provide sufficient power lines to transport electricity from north to south Scotland let alone between continents. The key barriers are costs and complex legislation.
Just for those wind energy sceptics out there – the article claims that wind provided almost 40% of Spanish Power earlier this year.
Marine energy has great potential for the future and is certainly not dead end. However there does need to be much more investment in the technology to really give it a kick start. Hopefully the increased renewable obligation certificates will do the trick.
