It was odd last week to have two Viva Lewes columns with opposing views about solar pv, with me singing its praises and The Trouble With feeling quite grumpy about it. At the risk of boring some readers, I’d like to address TTW’s concerns one by one.
Our demand for electricity is in the winter, when the sun shines less.
Sorry, but this is irrelevant. Every kilowatt hour of electricity produced by renewable energy, summer or winter, is a kilowatt hour not produced by fossil fuels. Both CAT’s Zero Carbon Britain and David McKay’s excellent online book Sustainable Energy without the Hot Air outline how Britain can power itself renewably through a spread of technologies, including solar photovoltaics (pv).
Solar PV is too expensive.
Partly because of feed in tariffs (FITs) being taken up with gusto in 40 other countries, prices are falling, fast. Industry statistics show that the price of modules has halved in the last ten years with most of that drop in the last three years (see graph here). There are plenty of developments documented in the technical press that ensure there will be further drops as long as the market keeps growing. Even without FITS, solar pv is becoming affordable: on a good, medium sized roof a 3kW system can be installed for £10,000. Given industry projections for the cost of electricity, the payback for that is 18 years. The cost of electricity is rising by 6% a year (the average over the last 10 years) and set to rise faster, as fossil fuels deplete.
The rest of us subsidise the Feed in Tariffs.
The total cost to date of the FITs has been less than 1p a month to domestic bills and meanwhile thousands of new green jobs have been created along with tax and national insurance income to the government. In fact the inverse is true: those people who continue to use electricity from fossil fuels are being subsidized by those of us who use renewable energy. The cost of climate change is enormous; according to the influential Stern Report, the financial cost to society of not going renewable is far greater than the investment costs of renewables. FITs are a way of shifting costs to the polluters.
We should spend the money on alternatives to fossil fuels.
To get off fossil fuels we need to invest in a spread of renewable technologies, including solar pv, according to the sources sited at the beginning. If TTW is talking nuclear, David McKay cites a 2008 statistic of the cost of simply decommissioning – let alone building - UK’s nuclear power stations as up to £73 billion or £1200 a person. Out of the Department of Energy and Climate change budget of £3 billion and falling, nuclear decommissioning alone will cost £850 million this year, £950 million next year and £1.1billion the year after. And that’s just the financial cost.
Is shareholding in a local solar power station a good bet?
Well, TTW, that’s up to you to decide. Myself, I am investing (£250) not just because of the money but because it’s something I want to help make happen. If you want to find out more, the full share documents will be issued at Ovesco’s launch of the share offer next Tuesday 19 April, 7-9pm at Lewes Town Hall. Anyone’s welcome, investors or not, to the event, which will include an Energy Question Time and free refreshments. There’s an incredible energy revolution beginning here and I’m proud to be part of it.
