Renewable energy can feel a little bit “one foot forward, one foot back” at times. Yet, the shift towards a majority renewable energy model is an inevitability; driven by climate commitments, rising fuel costs, and a collective desire for cleaner, more efficient alternatives.
While the spotlight often shines on solar panels, wind farms and electric vehicles, there’s a less visible piece of the puzzle… it’s where the members of our tribe come in – innovative electronic engineering.
Without it, most of the systems we rely on to capture and control renewable energy efficiently just wouldn’t work. At Ignys, we know that good engineering makes the difference between ideas that stay on the whiteboard and solutions that work in the real world… so read on.
Going green isn’t just plug and play
Green energy is fantastic. It’s clean, it’s becoming more cost-effective, but real-world implementation can be another story.
Renewable energy sources like solar and wind are naturally unpredictable. They don’t produce a steady stream of power like fossil fuel plants. The wind drops, the sun goes down… so how do you make that stream of energy reliable enough to consistently power a home, a business or even a city?
This is where the smart engineering comes in. You need intelligent systems to convert, regulate, store and distribute that power effectively. It’s not about creating energy; our environment creates more than we’ll ever need – it’s about capturing and managing it intelligently.
Power electronics
If you’ve ever looked at a solar panel, it might surprise you to learn that it generates DC electricity, not the AC you use in your home. So straight away, we need power conversion. That’s the job of inverters and converters. Precision-engineered systems that take raw, variable input and make it safe and usable.
But that’s only the beginning. Effective power management ensures you’re getting the most energy out of your system, adapting in real-time to changes in sunlight or wind conditions. Techniques like Maximum Power Point Tracking (MPPT) allow your system to intelligently adjust and operate at peak efficiency, every minute of the day.
Smarter grids for a smarter world
Our traditional power grids weren’t built for the complex energy flows that come with renewables. Electricity used to flow one way: from big power stations to homes and businesses. Today, it’s two-way, thanks to home solar panels, local wind farms and storage batteries.
That means we need smart grids—systems that can monitor and react in real time, shifting energy where it’s needed, preventing overloads, and spotting faults before they become failures. It’s a digital revolution happening alongside the green one, and electronic engineering is right at its core.
At Ignys, we’ve designed embedded systems and control platforms that do exactly this. Clever tech that quietly keeps everything running smoothly in the background.
The storage challenge (and how engineers are winning)
One of the biggest hurdles with renewables is energy storage. If your wind turbine generates loads of electricity overnight, but demand peaks in the afternoon, you need a way to store that excess power and release it when it’s needed.
That’s where batteries come in—but they’re only part of the answer. Battery management systems (BMS) are crucial. They monitor battery health, prevent overheating, balance cell voltages, and make sure everything is working efficiently and safely.

EVs, fast charging and the grid of the future
Electric vehicles are another example of how green energy is changing how we think about power. They don’t just replace fossil fuelled alternatives, they’re powered from the grid, they can store energy it and even give it back when needed. But to make that possible, you need highly advanced electronics: inverters, controllers, communication systems, and chargers that can safely handle fast DC power.
Designing this kind of kit takes serious expertise. Everything needs to be energy-efficient, reliable under high loads, and built with safety in mind. To date we’ve designed and tested a plethora of EV chargers – this is exactly the kind of challenge we love solving at Ignys.
Embedded control: the brains behind the operation
Green energy systems are incredibly dynamic. A solar panel might adjust its tilt during the day. A wind turbine changes blade angles to capture more energy. Water flow in hydro systems gets controlled to maintain steady output.
These systems don’t run themselves; they rely on embedded control: microcontrollers, sensors, firmware, and smart algorithms. That’s where good engineering makes all the difference. It’s not just about having the parts, it’s about how they’re designed to work together, adapt, and respond in real time.
Looking ahead: AI, automation and next-gen materials
The future of green energy will be shaped by innovations in AI, automation, and materials science. At Ignys, we’re already exploring how machine learning can optimise energy systems in real-time. AI can help predict solar output based on weather data or adjust energy usage in smart homes without anyone lifting a finger.
We’re also keeping a close eye on new power electronics based on wide-bandgap semiconductors like silicon carbide and gallium nitride. These materials offer faster switching, higher efficiency, and lower heat generation—key ingredients for the next generation of energy tech.
Final thoughts…
It’s easy to focus on solar panels and wind turbines as the face of green energy. But behind the scenes, it’s electronic engineers who are solving the real problems, making sure these systems are efficient, reliable and scalable.
If we’re serious about hitting net-zero targets and building a truly sustainable future, we need to keep investing in the innovation that makes it all work.
Green energy isn’t just the future. It’s happening now—and engineering is what makes it real.
