For the first time, renewable energy has overtaken coal as the world’s largest source of electricity generation.

According to new data from the energy think tank Ember, growth in solar and wind power was so strong in the first half of 2025 that it met all of the additional global electricity demand, helping to reduce coal and gas use for the first time in decades.

Ember described this as a “crucial turning point”, one that signals real progress in the global shift towards cleaner, low-carbon energy.

Of course, the isn’t the same everywhere. Some regions are moving faster than others. China and India are leading the way with huge investments in renewables, while other nations, including the US and parts of Europe, are still facing challenges as older fossil-fuel infrastructure lingers.

But overall, the shift to renewables is improving and the and the pace of change is accelerating.

At SPC, we see this transition happening every day. More projects are being designed around low-temperature, renewable, and hybrid heating systems, and the demand for reliable, energy-efficient equipment has never been higher.

That’s where our industrial product range comes in:

• Industrial Radiant Panels – Delivering direct, comfortable warmth by heating people and surfaces rather than air, reducing wasted energy in large, open spaces such as warehouses and factories.
• Industrial Air Curtains – Preventing warm air from escaping through open shutter doors and loading bays, helping to maintain indoor comfort and cut unnecessary heat loss.
• Unit Heaters – Robust, high-performance heating units designed to integrate with renewable-ready systems, including those powered by heat pumps or district heating.

Each of these solutions plays a role in helping businesses reduce carbon emissions, improve efficiency, and build resilience as energy systems evolve.

At SPC, we’re proud to be part of the progress, supporting the industries that keep the world moving as they embrace cleaner, more sustainable ways of working.

Our CIBSE-approved CPD covers decarbonisation, embodied carbon, and renewable and sustainable heating system design in detail. Contact Ben Sword to book your session today!

At SPC, we’re passionate about sharing our industry expertise and supporting the development of better building environments. Over the past few years, our Radiant Heating & Cooling CIBSE CPD has become one of our most popular sessions, offering valuable insight into the design, application, and performance of radiant panel systems.

Our team has delivered this CPD to designers, consultants, engineers, and architects across the UK, helping raise awareness of good design practices, real-world applications, and energy-efficient solutions for modern buildings.

SPC recently supported a valued customer with a frost HVAC coil survey at a government building in the South. The on-site photos clearly demonstrate the impact that corrosive air can have on unprotected HVAC coils, particularly when air is drawn directly through the AHU intake.

To prevent this kind of damage, coil protection is essential. At SPC, we use Blygold coating to safeguard coils from corrosion caused by coastal or industrial pollutants. This helps extend the life of heat exchangers in your HVAC equipment, improving performance and lowering maintenance costs.

Whether your project requires heating, cooling, steam, or DX coils, SPC provides durable, reliable HVAC coil solutions built to last.

As temperatures drop, warehouses, distribution centres, and other industrial spaces face a common challenge: large shutter doors constantly opening and closing allow cold air to rush in, making it harder and more expensive to maintain comfortable indoor conditions.

SPC iForce Industrial Air Curtains create a high-powered barrier of air across open doorways, helping you to:

• Maintain indoor temperatures
• Reduce energy costs
• Protect staff comfort

Available in widths of 1.5m, 2.0m, and 2.5m and stackable to cover doorways up to 6m high, our air curtains offer a tailored solution for any space.

Although it may still feel like summer, colder days are on the way. When temperatures across the UK suddenly drop, often well below freezing in late autumn, HVAC coils can be at risk.

As water inside a coil freezes, it expands by around 9%, creating pressure that can crack or split the tubes. The result? Costly leaks, system downtime and unexpected repair bills.

With over 50 years of expertise, SPC is a trusted British HVAC manufacturer, based in Leicester, known for delivering high-quality, energy-efficient products.

Perfect for low water temperature systems such as heat pumps, our solutions support decarbonisation, energy efficiency and long-term sustainability.

At SPC, we pride ourselves on delivering bespoke services and end-to-end project support, ensuring every installation meets your specific requirements.
