Where We Stand in 2025: Is the UK Truly Going Green?

Current Renewable Share in the National Mix

As it stands, about 47% of the UK’s electricity comes from renewable sources. That figure includes wind, solar, hydro, and bioenergy. Fossil fuels still make up just under 40%, while nuclear covers roughly 15%.

Here’s what that breakdown looks like:

This isn’t bad progress, considering that just a decade ago, fossil fuels held over 70% of the share. But electricity is only part of the story. Heating, transport, and industrial energy still rely heavily on gas, petrol, and diesel.

Who’s Powering Us? The Main Players in 2025

Wind power is currently the heavyweight, generating around 34% of the UK’s electricity—most of it offshore. It’s clean, consistent, and the North Sea’s become a proper goldmine of spinning turbines.

Solar power is growing, but still trails behind at about 8%. Seasonal variability and planning resistance hold it back, especially in England.

Bioenergy (which includes biogas, landfill gas, biomass, and transport biofuels like ethanol and biodiesel) provides a modest but growing 3%. Not headline-grabbing, but absolutely vital in transport and industrial use.

Hydro sits around 2% and likely won’t change much—it’s limited by geography.

Nuclear isn’t renewable, but it’s low-carbon and still covers 15%, mainly from ageing reactors.

Challenges and Setbacks

Despite all the green chatter, there are issues. Offshore wind has seen supply chain delays and rising costs. Solar farms spark debates over land use, especially in farming regions. Biofuel adoption remains sluggish, especially in HGV fleets. And hydrogen? Let’s just say it’s still more theory than practice.

The Forecast for 2035: What the Experts Expect

Government Goals vs Reality

The UK government’s aiming for a net-zero power grid by 2035. That means no fossil fuels unless their emissions are fully captured. On paper, it’s achievable. In practice, it’ll take serious investment and a bit of luck.

According to the Climate Change Committee and National Grid ESO, we’ll need to double our low-carbon capacity in ten years. That means more wind, more solar, a new approach to heating, and serious innovation in transport fuels.

Wind Power: Still King of the Hill?

Wind will likely stay at the top, projected to make up around 40% of the energy mix by 2035. Several large-scale projects in the Dogger Bank and Hornsea zones will come online by then, supported by better grid infrastructure and smarter storage tech.

Floating turbines could even unlock deeper waters off the Scottish coast, opening up new wind corridors.

Solar: Sleeping Giant or Oversold Promise?

Solar power is expected to more than double, rising from 15GW today to around 40GW in 2035.

This growth will rely heavily on domestic rooftop installations and clever integration with home batteries and heat pumps. Solar won’t ever be our main source, but in combination with storage, it’ll punch well above its weight.

Bioenergy and Green Fuels: Niche or Necessary?

Here’s where things get divisive. Some experts see bioenergy as a bridging fuel, helping decarbonise sectors like aviation and heavy industry. Others call it inefficient and land-intensive.

Still, green fuels—including advanced ethanol, biodiesel, and synthetic fuels—are expected to provide 10% of energy needs by 2035. Their role in decarbonising older vehicles, planes, and ships will be key.

Biogas from food waste and slurry will also help power combined heat and power systems across rural areas.

Green Hydrogen: Breakthrough or Buzzword?

Hydrogen’s been hyped for years, but mid-2025 still sees more talk than delivery. By 2035, that could change.

Expect 8% of the energy mix to come from hydrogen, mainly powering industrial furnaces, backup power stations, and perhaps heavy transport. But large-scale rollout depends on cheap electrolysers and lots of surplus renewable electricity.

---

What Will the 2035 Energy Mix Look Like?

Let’s stack it up visually.

The new mix could look like this:

• Wind: 40%
• Solar: 20%
• Bioenergy: 10%
• Green Hydrogen: 8%
• Nuclear: 10%
• Hydro: 2%
• Fossil Fuels (with CCS): 10%

It’s worth noting that even with a big push, fossil fuels won’t disappear entirely—but they’ll be cleaner or offset by carbon capture. That’s the compromise built into most forecasts.

The Transport and Heating Question

By 2035, most new cars will be electric. Home heating is shifting towards heat pumps, though retrofitting old housing stock remains expensive and messy.

This all adds pressure to the electricity grid. Can renewables carry the extra weight? If rollout keeps pace, yes. But if we fall behind, there’s a risk of shortfalls—especially in winter.

Winners, Losers, and Big Questions Ahead

Who Stands to Benefit the Most?

If things go to plan, the green sector could add tens of thousands of jobs—especially in wind engineering, solar installation, and hydrogen development. Coastal towns and ex-industrial areas could see a real revival.

The biggest winners will be those who invest early, upskill fast, and focus on flexible, localised energy solutions.

What Might Stall Progress?

Here are five major risk factors:

1. Planning delays – NIMBY resistance is slowing wind and solar approvals.
2. Supply chain gaps – We still rely heavily on imported materials for renewables.
3. Political wobbles – A change in government priorities could shift funding.
4. Grid limitations – Upgrades to infrastructure are slow and costly.
5. Public confusion – Misinformation and resistance to lifestyle changes might limit adoption.

Final Thoughts: The 2035 Snapshot in Perspective

Will we look back in 2035 and see a green energy success story? I think we might—if we keep moving. The UK’s got the brains, the tech, and the wind in its sails. But we’ll need clear policies, serious funding, and public backing to stay on course.

One thing’s for sure: energy in 2035 won’t look like it does today. Whether that’s something to celebrate or worry about… well, that’s up to us.

Nuclear energy’s public relations problem stems from deep-seated fears about safety, waste, and past disasters. Overcoming this issue is a steep uphill battle. Despite advancements in technology and safety, the public remains sceptical. It will struggle to shed its negative image until nuclear energy can unequivocally demonstrate its safety and environmental benefits. So, while nuclear energy has the potential to play a critical role in our future energy mix, solving its PR problem is unlikely in the short term.

The Roots of Public Unease with Nuclear Energy

The discomfort many people feel about nuclear energy is rooted in its history. Memories of catastrophic events like the Chernobyl disaster in 1986 and the Fukushima Daiichi accident in 2011 loom large in the public consciousness. These incidents, though rare, showcased the potential for devastating consequences when things go wrong. The idea of a power source that, if mismanaged, could cause long-term environmental and human harm is inherently unsettling.

Moreover, there’s the issue of nuclear waste. The public worries about the long-term storage of radioactive materials, which remain hazardous for thousands of years. The fear of accidents during transport or storage adds another layer of anxiety. These concerns are amplified by a general lack of understanding about nuclear energy, leaving space for imagination and fear to fill the gaps. Consequently, nuclear energy has been cast as a risky, almost menacing, technology, regardless of the strides made in improving safety.

Can Sustainable Resources Meet the UK’s Future Energy Needs?

As the UK strives to reduce carbon emissions, there’s an ongoing debate about whether renewable energy sources like wind, solar, and hydropower can meet the country’s energy needs in the coming decades. The UK is in a fortunate position with its extensive coastlines, making it ideal for offshore wind farms. Solar energy is also becoming more efficient, and energy storage technology is improving.

However, there are challenges. The UK’s weather is notoriously unpredictable, leading to wind and solar energy production variability. While advances in storage could help bridge gaps, the current technology isn’t yet capable of storing enough energy to cover periods of low production. Moreover, the demand for electricity is expected to rise as the country transitions to electric vehicles and heating systems, further straining the grid.

Renewable energy will likely play a significant role in 30 years, but relying solely on it to cover the UK’s entire energy demand is ambitious. The need for a stable, continuous power source remains, which brings us back to nuclear energy as a potential candidate to fill this gap.

Is Nuclear Energy the Only Viable Alternative?

If sustainable resources fall short of meeting future demand, the question arises: what other options does the UK have? While less polluting than coal, natural gas still contributes to carbon emissions and is a finite resource. Biomass and biofuels offer potential but are limited by land use concerns and other environmental impacts.

Nuclear energy, with its ability to continuously provide large amounts of low-carbon electricity, presents itself as a viable alternative. Unlike renewables, it doesn’t depend on weather conditions and can deliver a steady supply of power. In a future where demand is high and the need to cut emissions is urgent, nuclear could indeed be a crucial part of the energy mix.

However, it’s not without its drawbacks. The high cost of building and decommissioning plants and the unresolved waste issue are significant barriers. But if these challenges can be addressed, nuclear might be the only scalable solution for reliable, low-carbon energy.

The Green Movement’s Opposition to Nuclear Energy

Given its low-carbon credentials, the green movement has traditionally opposed nuclear energy, which might seem counterintuitive. This opposition stems from several factors. First, however small, the risk of catastrophic accidents contradicts the movement’s ethos of minimising harm to people and the planet. Given nuclear technology’s dual-use nature, the potential for nuclear weapons proliferation is also a concern.

Then there’s the issue of nuclear waste. For many in the green movement, creating hazardous waste for millennia is fundamentally incompatible with sustainability. The long-term storage solutions are viewed as temporary and inadequate, leaving future generations to deal with the consequences.

The green movement also argues that investment in nuclear energy diverts resources from developing and deploying renewable technologies. They believe that with sufficient investment, renewables can meet global energy needs, making nuclear unnecessary. In their view, the risks and drawbacks of nuclear energy outweigh its benefits.

How Latest-Generation Reactors Could Address Public Concerns

Despite the challenges, advancements in nuclear technology offer hope for overcoming public fears. The latest-generation reactors, such as Small Modular Reactors (SMRs) and Generation IV reactors, are designed with enhanced safety features and efficiency.

SMRs, for example, are smaller and more flexible than traditional reactors. They can be built in factories and transported to sites, reducing construction time and cost. Their smaller size also means that they produce less waste. Moreover, these reactors have passive safety systems that don’t rely on human intervention to prevent accidents, reducing the risk of human error.

Generation IV reactors are even more promising. They’re designed to use fuel more efficiently and produce less waste. Some types can even use existing nuclear waste as fuel, helping to reduce the overall amount of radioactive material that needs long-term storage. These reactors also aim to be inherently safer, with designs that minimise the risk of meltdown and other catastrophic failures.

If these technologies can be successfully developed and deployed, they could significantly reduce the risks associated with nuclear energy. This, in turn, might help to ease public fears and improve the technology’s image. However, widespread acceptance will depend on effective communication and education efforts to build public trust.

Conclusion: A Steep Hill to Climb

Nuclear energy’s PR problem is rooted in legitimate concerns about safety, waste, and the potential for catastrophic failure. While it offers a viable alternative to fill gaps in renewable energy production, particularly as demand rises, the public remains wary. The green movement’s opposition further complicates matters, focusing on the long-term environmental impacts of nuclear waste and the potential diversion of resources from renewables.

Yet, the latest-generation reactors bring hope. With enhanced safety features, reduced waste production, and the potential to use existing nuclear waste as fuel, these technologies could help address some of the key concerns. However, whether this will overcome decades of fear and scepticism remains to be seen. For nuclear energy to solve its PR problem, it must prove its safety and efficiency and win the trust of a public that has long been uneasy about its risks.…

OK, in the recent months, people have been talking about nuclear energy and biofuels a lot. Since the rise of global gas prices due to various geo-political reasons, the UK Government has been looking at ways to replace dependance on fossil fuel. Natural gas in particular.

Are Biofuels Harmful to Humans?

This is an important question, one that deserves an answer. Biofuels are made with plants and other organic materials, which could pose a risk.

But research shows that biofuels produced safely can help mitigate climate change while producing fewer greenhouse gas emissions than traditional fuels like gasoline and diesel.

This means that using biofuels responsibly could significantly reduce air pollution and create a healthier planet for us all.

Plus, modern technologies have helped to ensure that the production of biofuels has very few negative impacts on the environment or human health.

So the answer to this important question is no – when used safely, biofuels are not bad for humans.

What is the Main Problem with Biofuels?

Our dependency threatens our environment on fossil fuels for energy, but biofuels provide an eco-friendly and sustainable alternative.

However, developing and using this fuel type comes with its own challenges.

One of the biggest hurdles is finding sustainable methods for converting biomass into fuel. When done incorrectly, this process can be inefficient and pollute the environment. The production and distribution of biofuels cannot match the scale of gasoline and diesel production, creating logistical problems in some areas.

Advances in other renewable energy sources have outpaced growth in biofuel technology over the past decade, making it difficult for biofuels to compete on cost. This can limit investment opportunities in research, development & deployment (RD&D) and slow long-term progress.

The scarcity of available land also presents another challenge; growing crops to use as feedstocks requires vast amounts of farmland and water, which may not be available where it’s most needed, resulting in a lack of access to such resources by local communities who could benefit most from them.

Global agricultural subsidies have recently come under scrutiny because they spur overproduction while having significant environmental impacts due to soil erosion, herbicide runoff and other types of pollution from intensive farming operations.

So, biofuels are an important part of the effort to reduce emissions. Still, there needs to be careful consideration of additional sources needed for RD&D efforts dedicated to reducing these issues before wide adoption can occur.

Is Nuclear the Cleanest Energy?

Nuclear energy has long been lauded as a clean and efficient source of electricity. But closer examination reveals that the reality may be significantly more complex.

Despite being relatively low-emission in terms of conventional pollutants, nuclear power plants create radioactive waste materials that remain hazardous for extended periods. Additionally, uranium mining and enrichment processes may harm the environment and local communities.

Nuclear power contains tremendous risks for both people and the planet. The catastrophic failure of any single plant could have devastating consequences for entire regions, with long-term environmental damage potentially taking decades or centuries to recover from.

Atomic energy does have some safety benefits; operating it within parameters gives an orderly form of energy generation with comparatively little effort required from its end users. But such power must be used responsibly to maintain effectiveness and exclude potential risk.

While there are certainly positive attributes to nuclear power, they should not be considered as making it inherently cleaner than other forms of electricity generation, which may provide very similar levels of return when balanced against safety and longevity requirements.

Biofuel vs Nuclear Fuel

Nuclear power has a lot of potential for providing clean, sustainable energy. The prevalence of nuclear power plants and reactors worldwide is a testament to this.

But biofuels offer their own advantages that nuclear cannot match. They are environmentally friendly and produce less air pollution than fossil fuels like coal and oil.

Not only that, but when it comes to transportation emission standards, the use of biofuels helps lower those levels significantly compared to just using regular combustible fuel sources.

Transport is responsible for 27% of total greenhouse gas emissions in the EU, and several pieces of legislation have failed to bring about major changes. (Source: euractiv.com.)

Plus, they generate fewer emissions during production, which helps reduce greenhouse gas emissions into the atmosphere.

Another unique attribute of biofuels is that they are renewable, making them sustainable as opposed to nuclear fuel, which can be used up once its source has been depleted.

To harness both sources effectively, we need to incorporate their individual benefits into our energy mix to access a stronger portfolio regarding fuel types and availability.

Fusing both fuels could provide the necessary infrastructure to ensure global energy reliability and sustainability without straining our environment or negatively impacting our planet’s precious resources.

Both nuclear and biofuels offer distinct advantages when it comes to providing clean and sustainable energy. Nuclear power has the potential to provide large amounts of energy in a relatively small space, while biofuels are renewable and have little to no emissions during production. Both sources have their own pros and cons, but when used together, they can create an effective mix that provides reliable energy with minimal environmental impact.…
