Solar Arrays

Debate between Luciana Berger and Sheryll Murray

Thursday 11th July 2013 Westminster Hall

[Luciana Berger (Liverpool, Wavertree) (Lab/Co-op)]

It is a pleasure to serve under your chairmanship this afternoon, Sir Alan. I congratulate the hon. Member for Totnes (Dr Wollaston) on securing what has been an interesting debate. Hon. Members have made many important points, and I hope to touch on a number of them.

May I begin my remarks with something a little different? I want to talk about the American inventor, Thomas Edison, who will need little introduction to hon. Members. He was one of the great pioneers of the late 19th and early 20th centuries. His achievements include the patented system for electricity distribution and the practical electric light bulb. The crux of the debate is that over the next decade a quarter of our power supply will be shut down or switched off for good. We are talking about how to keep the lights on. It is therefore appropriate to look at something Edison said about the future of energy more than 80 years ago. Shortly before his death in 1931, he told a friend:

“I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.”

Ever the visionary, Edison understood the value of planning ahead, making the most of our natural resources and investing in a low-carbon future, and that was before scientists had discovered that our climate was changing.

The solar opportunity is not a new one, therefore, but it is one that we desperately need to seize with both hands. Fifteen per cent. of our energy is targeted to come from renewable sources by 2020, but there are some big question marks about whether that target will be achieved. If we are to have any hope of meeting it, solar needs to be a vital part of our energy mix in the years and decades ahead, and many Members have acknowledged that in their contributions. I also welcome the question that the hon. Member for Totnes asked about the role that marine and tidal might play in the future energy mix.

[Sheryll Murray]

Does the hon. Lady agree that the most appropriate siting of solar energy panels is on the roofs of industrial or other buildings and out of sight, or does she promote covering vast areas of our valuable productive farmland with solar panels?

[Luciana Berger]

I thank the hon. Member for her intervention. I will go through all her points in my contribution. If she has further questions, perhaps she will wait for my response, and I will be more than happy to come back to her.

Solar has numerous benefits to offer, and some have been picked up in the contributions that we have heard. It can complement other, less predictable renewable technologies. We do not always know how windy it will be, but we know to the minute what time the sun rises each morning and sets in the evening, so we can work out exactly what the minimum output will be.

Research shows that solar produces electricity at times of year when wind and hydro power generate less. Solar parks can help energy suppliers to balance supply from other forms of generation. Crucially, that helps to reduce the cost of supply to the bill payer because suppliers are less reliant on the short-term energy market, where power is more expensive. The time when electricity is generated from solar technology is a good match for demand, especially in daytime factory production, office and retail spaces. It would be misguided to put all our renewable eggs in one basket. This debate is a reminder about why it was folly for the Government not to commit to setting a decarbonisation target in the Energy Bill to clean up our power sector.

Looking at what is happening globally, the rest of the world is moving fast with solar. For example, the United States has today become the fourth country in the world to break through the 10 GW barrier for solar PV capacity, and it is not only large countries such as China that have broken through that barrier but Germany and Italy. In comparison, the UK currently deploys around 2.5 GW of solar PV capacity.

The Minister said recently that he wants to make the UK the destination of choice for any solar company looking to invest in Europe. I recognise and acknowledge that solar is a core technology in the revised debt renewables road map. He has also said that it is his ambition to deploy up to 20 GW of capacity by 2020. That is a fantastic ambition, which I would like to see realised urgently. Does he believe that it can be met solely on brownfield and roof top sites?

I understand that around one in 70 homes currently has a solar panel on its roof, and I hope that that number will increase. I acknowledge the contributions about community energy projects. I visited an energy co-operative in Brixton recently. It is using the roofs of social housing and reinvesting money raised from that project into the local community. However, we must acknowledge that roof-mounted solar projects often have to compromise their output to fit the architectural constraints of the building, and many people do not have the choice of having a solar panel. I would love one on my roof, but unfortunately it faces north so I cannot.

Ground-mounted projects can be orientated for maximum output, and many hon. Members have raised the planning and environmental issues associated with them. First and foremost, it is absolutely right that we take care to protect our rural landscape and our natural environment, in the same way as with all energy generation. Consent for generating stations of 50 MW or smaller is a matter for local planning authorities. Some applications will be for appropriately sited installations and will receive planning permission; others will not be appropriate and will not go ahead, as with any development.

[Luciana Berger]

I thank the hon. Member for her intervention, and I will respond to that point in a moment.

Hon. Members have views about individual developments and applications that are being considered in their own constituencies. It would not be correct for me to comment on them. However, national policy guidance is that local planning authorities should avoid prime agricultural land for large-scale solar projects.

[Sheryll Murray]

I do not know whether the hon. Lady heard my speech, but I have asked the Minister to confirm that national planning policy guidance will be amended in the same way as that for wind turbines. The guidance in place at the moment is not stopping the increasing use of good, productive farmland for solar arrays. The hon. Lady may not be aware of that because I believe that she does not represent a rural constituency. It might be good if she went back and tried to find out exactly what was happening in the countryside.

[Luciana Berger]

I thank the hon. Lady for her contribution. I do not represent a rural constituency, but I have spent a lot of time in rural constituencies throughout the country when visiting different projects. I understand the concerns that she raises, and having spoken extensively to the industry, I know that the Department is developing, and has been for a while, a charter on how some of the issues can be overcome. I hope that the Minister will refer to it. I will not speak for him, because I am not the Minister, but I expect that we will hear more about that and what the sector has been working on extensively with the Government to overcome some of the challenges that have rightly been raised by hon. Members.

I also know from speaking to the industry that many, but not all, solar companies voluntarily focus on lower-grade agricultural land where crop cultivation is unlikely, but I take on board the comments and representations from hon. Members. As they have said, many farmers are facing the challenge of tough times. It is not their fault, and we must do everything we can to support them. They are being offered opportunities to diversify their income and to keep farming.

On some projects, sheep can graze beneath the panels, and it is possible for solar parks to play a role in encouraging greater biodiversity in our natural environment. I understand that land can be resown in a way that provides food and habitat for pollinating insects, and that just last week a scheme was launched by the Bumblebee Conservation Trust to establish wild flower meadows across Solarcentury’s solar park sites.

I look forward to the Minister’s response to my questions, and I will conclude with this final thought. Just a fortnight ago, the Select Committee on Energy and Climate Change reported that the UK had fallen behind in meeting our carbon reduction targets. If we are to get back on track we need an approach that makes the most of all our renewable energy sources, and that must include solar.

I began by with some old words of Edison about the untapped potential that solar technology presents. This has been a fine debate, but it is not one that I would want our successors to quote in 80 years. Clearly, there are issues to be aware of and we must tread carefully when necessary, but we must look at the opportunities for solar and I hope that we can make the most of it. I look forward to hearing the Minister’s response.
