The energy landscape is undergoing a significant shift, and it's time to challenge the long-held beliefs of the fossil fuel industry. A recent report by the International Renewable Energy Agency (IRENA) has revealed a game-changer: clean energy, when combined with innovative storage solutions, can now compete with fossil fuels on price and reliability. This development is not just a theoretical concept but a practical reality, as evidenced by the report's findings.
The Power of Firm Renewables
IRENA's report focuses on "firm" renewable systems, a combination of solar, wind, and battery storage. In regions with favorable conditions, this mix can provide electricity around the clock, rivaling the reliability of fossil fuels. The cost of solar-plus-battery systems has dropped significantly, now ranging from €50 to €75 per megawatt-hour. This is not only competitive with new coal plants in China but also undercuts new gas power globally. The key driver of this change is the dramatic fall in battery prices, which have decreased by 93% since 2010, according to IRENA.
Geopolitical Advantages
The benefits of renewable energy extend beyond cost and reliability. IRENA highlights how combining wind, solar, and batteries can reduce exposure to geopolitical shocks. For instance, Europe's reliance on fossil fuels, particularly gas, leaves it vulnerable to disruptions like the conflict in Ukraine or the instability in the Middle East. By diversifying its energy sources, Europe can enhance its energy security and reduce its vulnerability to these external factors.
Europe's Renewable Revolution
The timing of IRENA's report is particularly relevant for Europe. The continent is currently facing fossil fuel price shocks due to the ongoing conflicts. However, advocacy groups like Positive Money have found that renewables are already making a significant impact. In some European countries, electricity prices have decreased by almost 25% between 2023 and 2025, thanks to the increased adoption of renewable energy sources. This trend is set to continue, with countries like Denmark, Finland, France, Sweden, and Slovakia expected to save billions on energy bills this year due to their cleaner electricity mixes.
The Argument Against Renewables: Debunked
For years, critics have argued that solar and wind power are unreliable due to their dependence on weather conditions. However, IRENA's report challenges this notion. Battery storage is the game-changer here. Batteries can store excess electricity generated during sunny or windy periods and release it when needed, reducing the reliance on backup fossil fuel plants. This technology, combined with the falling costs of batteries, is set to make round-the-clock renewable power an increasingly attractive option, even for energy-intensive industries like AI and data centers.
A Brighter Future
The future of renewable energy looks promising. By 2035, some large-scale solar-and-battery projects could deliver continuous electricity for less than €45 per megawatt-hour in the best-performing regions. This development is a significant step towards a more sustainable and secure energy future. As Francesco La Camera, director-general of IRENA, stated, "The long-standing argument that renewables lack reliability no longer holds." It's time to embrace the potential of clean energy and its ability to challenge the dominance of fossil fuels.
