There has never been a more important time to invest in green technologies, yet many of us believe these efforts are doomed to failure. What nonsense, writes Chris Goodall
Myth 1: solar power is too expensive to be of much use
In reality, today’s bulky and expensive solar panels capture only 10% or so of the sun’s energy, but rapid innovation in the US means that the next generation of panels will be much thinner, capture far more of the energy in the sun’s light and cost a fraction of what they do today. They may not even be made of silicon. First Solar, the largest manufacturer of thin panels, claims that its products will generate electricity in sunny countries as cheaply as large power stations by 2012.
