I have thought of my hon. Friend in many ways, but I have never really thought of her as a roofer. However, I take her point: there are some interesting technologies. Building-mounted solar, and particularly, building-integrated solar—roof tiles fall under that category—is interesting. Encouragingly, the cost of the products is continuing to fall. Building-integrated solar is still relatively expensive, so it is unlikely to meet the golden rule of the green deal, but of course, green deal assessments will prompt people to consider such measures for their homes. Building regulations will also prompt developers to think about including them in homes of the future. I think there is huge potential for home-grown products, and my vision of the future is for everyone’s home to become, at least in part, a power station, and for a much more decentralised, distributed energy economy.
However, although I have big ambitions for the solar sector, let me be equally clear: deployment will not—and must not—come at any cost, nor in any place, and certainly not if it rides roughshod over the opinions of local communities. Solar has huge potential, and unlike some renewable technologies, it still enjoys huge popular support in many places. We must not allow a few badly sited or inappropriately scaled solar farms to undermine broader public support and effectively ruin it for the whole industry. I am determined to stop that happening.
Deployment of solar PV, like any other major renewable energy source, must be thoughtful, sensitive to public opinion, and mindful of the wider environmental and visual impacts. That is exactly the point that my hon. Friend the Member for South East Cornwall (Sheryll Murray)made in her excellent speech, really speaking up for the beautiful countryside in her constituency, and that point was also made by my other hon. Friends. I fully appreciate people’s worries. As my hon. Friends have described, the deployment of large-scale solar farms can have a very real, negative impact on the rural environment, particularly in very undulating landscapes. However, it is also important to say that the visual impact of a well-planned and well-screened solar farm can be properly accommodated within the landscape if done sensitively. Projects such as Powis castle and other National Trust sites are great examples of that. I was hugely impressed by the vision for a large-scale local energy park when I visited Kettering this week. It was a well-thought-out mix of onshore wind, biomass and solar, done with the consent and sympathy of the local community.
I also understand concerns about changes in land use away from agricultural use at a time when so many of us are increasingly concerned about food security and food production. We simply must not—and will not—allow prime agricultural land to be taken out of active food production. I am sensitive to people’s worries and have taken note of the specific cases highlighted by my hon. Friends the Members for Totnes and for South East Cornwall, and by my hon. Friend the Member for Tiverton and Honiton (Neil Parish). I will come back to that in greater detail, because fundamentally, I think we are on the same page.
Where are we now? What are we doing about this issue now? The fact is that my views are by no means exceptional. In fact, they are part of a broad consensus. The importance of getting the balance right and the imperative of retaining popular public support for solar is recognised by the vast majority of responsible solar
companies as well. That is why the Solar Trade Association is well advanced in producing its own code of conduct for its members. I greatly welcome that initiative, which is likely to address head on the need for sensitivity to local concerns and visual amenity—so important in my hon. Friends’ constituencies—the importance of community engagement; the encouragement of dual land use; community benefits, including education and employment; and importantly, the need, at the end of its life, to return the land to its former use.
In addition, the National Solar Centre, which I was very pleased to open earlier this year, has produced detailed guidance for developers and planners, giving strict parameters to ensure that large-scale developments are sustainable. The National Solar Centre will be promoting the use of those guidelines to local planners and developers through a series of roadshows around the regions.
As welcome as those voluntary initiatives are, they are not enough. The Government have a role to play, too, so we are taking action. I have created a Government and industry taskforce to look at land use and the sustainable deployment of large-scale solar PV. The first meeting of the taskforce was just yesterday, but I have taken on board the points that my hon. Friends have made about food security, and I will ask the taskforce, which is chaired by the National Farmers Union, specifically to look into the issue and report back. The taskforce will look at how to ensure responsible and sustainable deployment and make sure that it works with communities and local planners to a localism agenda.
This complex issue requires an effective and well-considered solution. For example, we could just demand that large-scale development occur only on brownfield sites, but the simple statement “Brownfield good, greenfield bad” does not stand up to scrutiny. A brownfield site could contain a site of special scientific interest or be contained within an area of outstanding national beauty. It could be in a part of the landscape—on a hill or the side of a hill—where it can be seen for miles around. Likewise, even plots of the highest-grade agricultural land could have areas that are lower grade and could be legitimately used for solar PV deployment.
That is why—this is most important—I want to see these decisions taken locally, within the framework of sensible, robust planning guidance from the Government and strong sustainability criteria. However, as I said in a speech to the solar sector earlier this year, in general, we do have a strong preference for commercial, industrial and brownfield development. The Wheal Jane solar farm at an old tin mine in Cornwall is a very good example of where brownfield land has been used to create a solar farm.
I have set up a second taskforce, using the industry and other sectors, with the aim of maximising the quantity of solar deployed on rooftops across the country—not just for domestic households, as it will consider how to maximise deployment on industrial buildings, supermarkets, Government buildings and car parks and in other sectors. This is a huge potential resource, and we must ensure that it is exploited. As I said, just 16% of these non-domestic roofs could yield my big ambition of 20 GW.
I understand the argument, however, that some solar farms currently being deployed can scar our beautiful countryside. We need to ensure that all developers are
sensitive to countryside and community. It is a fallacy to say that the deployment of ground-mounted solar PV must necessarily come with a negative visual impact, even in potentially sensitive and designated areas. The solar array at Powis castle, which I mentioned, is effectively shielded from the main visitor approach and the wider view not by industrial fencing, but by hedging. I have seen other larger arrays that sit comfortably in the landscape, and many others that do not.
We rarely hear mention of the spin-off benefits of sustainable solar PV deployment. Developers should always be encouraged to install natural visual screening such as hedges, which in themselves encourage biodiversity, by providing habitats for bird and insect life. The fallow land under solar PV panels can also encourage bird, insect and reptile life back to the fields. However, I certainly take on board my hon. Friends’ comments about the ridiculous notion that so many sites can be compatible with high-quality grazing land and the point that my hon. Friend the Member for Totnes makes about some of the pictures that are displayed in the advertising materials. That needs looking into.
I am mindful of the other side of the coin. Indeed, one responsible major PV developer, Solarcentury, has just entered into a partnership with the British Beekeepers Association to enhance the prospects for the great British bumble bee, which, I think, the hon. Member for Wells (Tessa Munt) alluded to.
