In a landmark moment for the global energy sector, a new report from independent think tank Ember has revealed that more than 40% of the world’s electricity in 2024 was generated without burning fossil fuels. This marks a major turning point in the transition towards cleaner, more sustainable energy systems, offering both environmental hope and new opportunities for innovation across industries.
At O’Keeffe Building Services, where sustainability is central to how we think, build, and innovate, this news is more than a statistic, it’s a signal of accelerating change and progress that aligns with our core values and our newly formed solar division.
According to Ember’s latest Global Electricity Review, wind and solar power accounted for a record 30% of global electricity generation last year. Hydropower and nuclear energy made up the rest of the non-fossil fuel mix, collectively pushing the total to over 40%. This is the first time in history that the world has produced such a large share of its electricity without relying on coal, oil, or gas.
The report also highlights a decline in coal-fired electricity, which dropped by 1%, and a flattening of overall fossil fuel generation. It suggests the world may have reached a peak in fossil fuel-based power generation, a crucial milestone on the path to net zero.
This shift is not just good news for the planet, it represents a seismic change in how economies, industries and individuals operate. A cleaner grid means lower emissions, more resilient infrastructure, and the potential for businesses and governments to align economic growth with environmental responsibility.
For sectors like construction, property development, and infrastructure, where O’Keeffe Solar is driving the transition, this shift creates exciting new opportunities to embed renewable energy at the heart of every project. From rooftop solar installations to integrated energy systems for commercial and residential builds, we’re helping clients harness clean power from day one. Whether it's designing solar solutions tailored to site conditions, optimising energy efficiency, or supporting carbon-neutral goals, we’re proud to be part of laying the groundwork for a smarter, more sustainable built environment.
The report acknowledges that while progress is encouraging, there’s still work to be done. Regions like Europe and the US are rapidly scaling up renewables, but others, particularly developing nations, need greater support and investment to decarbonise their grids.
To do our part, O’Keeffe’s will continue to explore innovative technologies and partnerships that prioritise sustainability without compromising performance or aesthetics. As global momentum builds toward cleaner energy and greener practices, we’re proud to be part of a community helping shape a low-carbon future.
Surpassing the 40% mark in clean electricity generation isn’t just a milestone, it’s a message. The world is changing, and faster than many predicted. For businesses, designers, policymakers, and communities, this is the time to act boldly, collaborate deeply, and build smartly.
Because the future isn’t just coming, it’s already being powered.
