Solar Farms

Edward Morello Excerpts

Thursday 15th May 2025 Commons Chamber

[Tony Vaughan]

As I said, the whole country needs to play its part in supporting the clean energy mission, but there needs to be a fair-share principle. If all the areas of the country with similar features to my constituency played their part, there would be less of an impact in particular areas. It is an entirely fair balance to strike. The Conservatives seem to be wedded to the idea that net zero is something we should not aim for, but they have absolutely no answer as to how we solve the climate crisis.

[Edward Morello (West Dorset) (LD)]

It might be worth making the point that only 10% of solar applications end up being built. The cumulative number of applications is completely irrelevant; what matters is the number that are actually built on the land, so while 7% of a constituency may be covered by applications, that is not a reflection of the percentage that will be built on.

[Tony Vaughan]

I thank the hon. Member for his intervention.

As a final point, there are real concerns about how ethical solar panel supply chains are. It is so important that we have robust mechanisms to ensure—

[Sir Edward Leigh]

My hon. Friend is absolutely right.

[Edward Morello]

Will the right hon. Member give way?

[Sir Edward Leigh]

I will make some progress and give way in a moment—I must be fair to other people.

There are solar schemes totalling 13,000 acres within a 6-mile radius of the small town of Gainsborough. Madam Deputy Speaker, can I please use a visual aid here? This map shows loads of solar farms—[Laughter.] I think I got away with it!

The Secretary of State approves these projects immediately; they go through his desk within a week. The cumulative effect of these solar installations is colossal in one small area, with numerous sites having been proposed and accepted in Lincolnshire. I want to say something to the Minister. Can he concentrate on what I am saying for a moment, because this is terribly important?

[Sir Edward Leigh]

We are not arguing against solar farms. All we are begging the Minister to do is take them together. We cannot have all these separate public inquiries. We have to look at the 13,000 acres all over Gainsborough. Is that not a fair point? Otherwise, it is totally unfair on one particular area. That is the only point we are making.

This is all done on a cheat—a so-called nationally significant infrastructure project, which was a device brought in by Tony Blair for nuclear power stations and that sort of installation. The Government are bypassing local democracy. That is what is so unfair, and it is why people feel disenfranchised in certain parts of England. I agree that if the Government distributed solar farms fairly all over the country, as the hon. and learned Member for Folkestone and Hythe said, there would be no argument, but the fact is that they are concentrating them so much in one small area of England. That is the argument.

[Edward Morello]

I would just point out that the reason we get that concentration: grid capacity. The grid is constrained in the areas where there is the highest level of demand. It is unconstrained in the areas where we have the least amount of demand, which are rural areas. That is why we keep getting applications there. If we upgrade the grid, we will not have that problem.

[Sir Edward Leigh]

That leads me to the point of whether solar power is really an efficient way of achieving green energy. It is land-intensive, with 200 times more land needed compared with gas, and it is inefficient during winter or cloudy periods. There are doubts about the carbon footprint. There is no clear evidence that energy generation over a 15-year panel lifespan justifies the embodied energy used in panel production—and we are never given reassurances on that point.

There are also environmental and safety issues. Placing battery energy storage systems in each field raises safety risks due to potential thermal runaway incidents. There is inadequate planning to provide water for firefighting in these fields. There are economic and community concerns—for instance, a negative effect on local tourism of the visual impact, and the lack of community benefits from large-scale solar projects compared with traditional local decision making—and I again make the national infrastructure point.

There are social and ethical concerns about possible connections between project stakeholders and forced labour in China, and we would like reassurances from the Minister in that regard. I asked him about that yesterday in the Chamber. I know we have achieved something with Great British Energy, but in this case we are talking about private companies, on which the concession that the Minister made yesterday will have no impact. There will be an impact on Great British Energy’s involvement if it can be proved that the solar panels are made with slave labour, but private companies will be able to go directly ahead.

I want to reply to the point made by my right hon. Friend the Member for South Holland and The Deepings (Sir John Hayes). Solar installations will take over good agricultural land, which is vital for Lincolnshire’s role as the breadbasket of England. Some 15% of regional farmland could be lost, undermining local agriculture, which is crucial for food security and sustainable farming.

In conclusion, covering our countryside with solar energy installations is environmentally harmful, economically unsustainable, a threat to food security, and damaging to local agriculture and tourism. Local opposition is widespread and strong, and the harms outweigh the benefits. Seeking permission for these sites via the use of nationally significant infrastructure projects is an abuse of NSIPs and subverts local democracy. It is part of this net zero craze that provides poor global value for money. It costs the UK taxpayer billions, and the net effect is cancelled out by minuscule increases in Chinese emissions. These applications should be taken in the round and, if necessary, refused.

[Edward Morello (West Dorset) (LD)]

I should declare that prior to entering this House, I spent the better part of a decade working in renewable energy finance. While I would not claim to be a solar expert, I could certainly write a whole speech debunking things that have been said today. For the record, solar panels have a lower carbon footprint per unit generated than the equivalent fossil fuel. They are 95% recyclable, and any solar farm development requires a glint-and-glare report before it gets approval if it is anywhere near an Air Force base or an airport. I will move on, because I could go on for a long time.

Those of us who believe in science know that tackling climate change means making bold, practical choices about how we decarbonise our economy. If we are serious about reaching net zero, tackling fuel poverty and protecting our countryside, we have to make renewables work for people as well as the planet. I have often made the point that the solar sector is not particularly good at communicating the benefits of a just transition to the population at large, so let me be clear: solar power means cheaper bills for consumers, protection against geopolitical insecurity and a greener future for the next generation.

[Greg Smith (Mid Buckinghamshire) (Con)]

I am listening carefully to the hon. Gentleman. So that we in this House and the whole country can hear clearly, is he saying that the Liberal Democrats fully support solar farms?

[Edward Morello]

The hon. Gentleman will be pleased to know that the answer is in my speech.

We have made substantial progress on decarbonising our power grid: a decade ago, just 6% of our energy came from renewables, and today, the figure stands at 42%. That is a national achievement we should be proud of, but we must go further, not just because the climate emergency demands it, but because renewables are the cheapest source of energy available.

Liberal Democrats believe strongly in expanding use of solar and other renewables to reduce our dependence on fossil fuels, improve energy security and bring down bills. Crucially, we believe that this must be done while protecting our natural environment. A strategic land use framework is essential if we are serious about delivering net zero while safeguarding our ability to produce food and restore nature.

We are asking more and more of the countryside—to produce food, capture carbon, generate clean energy, support biodiversity and provide space for housing, tourism and recreation. Without a joined-up approach, we risk pitting these priorities against one another. It is vital that a framework gives clear national guidance on where solar is most appropriate; sets out that solar should avoid high-quality agricultural land wherever possible; and encourages dual-use solutions that support both energy generation and nature recovery. It must enable local authorities to plan ahead with confidence, and to balance competing pressures in a way that reflects the needs and character of their communities.

Planning policy should not be dictated solely by where grid connections are available, but by a long-term vision of how we want our land to be used. It is a common claim that instead of putting solar panels on fields, we should put them on rooftops and car parks. I do not disagree, but having worked in the sector, I feel obligated—I make this point a lot—to explain the commercial realities. If utility-scale solar costs 50p per unit to build, rooftop solar is roughly double that, and carports double that again. Meanwhile, energy companies pay as little as 5p or 5.5p per unit for energy exported to the grid. That means that pure-export rooftop and carport solar does not stack up financially for investors, but that is something that the Government can fix. By mandating a minimum export price, we could unlock rooftop and car port investment, reduce pressure on farmland and cut consumer bills. Yes, wholesale energy buyers would earn a little less, but consumers, communities and the climate would all benefit. This is an easy win for a Government who have stated their commitment to net zero.

Ground-mounted solar will invariably remain part of the energy mix, and we cannot reach our climate targets without it, but projects must be done right, which means prioritising lower grade land and ensuring that new schemes come with tangible benefits for the communities they affect. Community benefit funds should receive a fair share of the wealth created. My hon. Friend the Member for Taunton and Wellington (Gideon Amos) has tabled new clauses to the Planning and Infrastructure Bill to deliver just that, alongside local authority powers to invest in energy efficiency and support street-by-street upgrades to reduce bills. In Scotland, for example, community benefit is worth £5,000 per installed megawatt per year. That means that a controversial large-scale solar project, such as the Kingsway solar farm in the constituency of my hon. Friend the Member for South Cambridgeshire (Pippa Heylings), would provide £2.5 million annually to the local community. That is the scale we should be talking about, and it must be the community that determines how and where that money is spent.

Today, about two thirds of UK solar is ground-mounted, but rooftop solar has a critical role to play and the Liberal Democrats are proud to be leading on that issue. We welcome the Government’s decision to adopt our policy of mandating solar panels on the roofs of new homes, which is a core part and first step of our rooftop revolution. We also call on Ministers to go further, by requiring new homes to meet net zero building standards and include provision for solar generation. When it comes to delivery, Liberal Democrats in local government are showing what can be done. From Barkham solar farm in Wokingham to Sandscale park in Westmorland and the thousands of car park panels installed in Portsmouth, we are delivering clean energy at scale, backed by communities.

Delivery must also be responsible, and I know that many of us are concerned about the number of solar farms being approved on our best agricultural land. Let me be clear: I am yet to meet a farmer who got into farming because they wanted to grow solar panels; this is happening because making a living from farming is increasingly impossible. We must ensure that farming is sustainable, profitable, and properly supported, so that farmers can keep doing what they do best, which is producing brilliant British food and looking after the land. I also share concerns about the use of nationally significant infrastructure project schemes, which are taking land out of use. That raises questions about long-term land use and oversight, particularly given the level of foreign investment in the sector.

Finally, a very quick word on standards—I appreciate that I am testing your patience, Madam Deputy Speaker. There are genuine concerns about labour practices in the global solar supply chain, but the industry is taking action. Having been part of the Solar Energy UK supply chain sustainability working group when it was first constituted, I can personally attest that the industry is taking the issue very seriously. Through the solar stewardship initiative, robust environmental, social and governance and traceability standards are being applied to ensure compliance with UK and EU laws. By the end of this year, certified facilities will be producing 100 GW of panels annually, which is five times the UK’s current capacity. As a result, we can be confident that we can meet our targets without compromising our values. The potential of solar is enormous. It can drive down bills, reduce emissions and create thousands of jobs, as well as protect our countryside.

[Madam Deputy Speaker (Caroline Nokes)]

I call the shadow Minister.
