Jeremy Leggett at Sunrise Celebration

Sunday at the Sunrise Celebration was dedicated to the Transition movement and there were talks around the issues of permaculture, peak oil and transition towns. Jeremy Leggett, the chairman of Solarcentury, gave a talk on peak oil (which we didn’t see) and then one on solar energy, which we did manage to catch.

There are some interesting things happening in the world of solar energy. It’s now expected that the cost of solar energy will match the cost of fossil fuel energy by 2013 and will then continue to fall. This is being driven by various factors, notably increased efficiency in the manufacture of the materials needed for panels and the panels themselves, and economies of scale as larger manufacturers come into the market. The efficiencies also mean that modern PV panels will pay back their energy (as opposed to financial) cost in less than two years.

At the same time, companies such as Shell and BP are pulling out of the renewables arena and in the UK, EDF and E.On are recommending a nuclear strategy to the government. Expect to see their PR departments aiming their guns at solar and other renewable technologies. There’s an illuminating Financial Times article by Jeremy on this.

The UK government is also planning to introduce a feed-in tariff scheme, whereby surplus renewable energy is sold back to the grid at a premium thereby encouraging uptake and helping to offset the initial cost. The exact details of the scheme will dictate its success and Jeremy has some strong ideas, as you’d expect from somebody in the industry that stands to benefit. But they do seem like sensible and sustainable ideas, and he came across as an approachable and committed man at the head of a company that’s trying to do the right thing.
