Recent findings from the International Renewable Energy Agency show that solar and wind energy have become more affordable than the lowest-cost fossil fuels worldwide, marking a major shift in the global energy landscape.
- Solar 41% cheaper than cheapest fossil fuels
- Wind power 53% less costly than fossils
- 91% of new renewable projects beat fossil fuel costs
What happened
In 2025, data from the International Renewable Energy Agency revealed a turning point where solar and wind power globally became less expensive than even the cheapest fossil fuels. On average, solar energy was 41% more affordable, while onshore wind projects cost 53% less, making renewables not only cleaner but also economically smarter choices. This economic shift was further highlighted by the fact that 91% of new renewable energy projects started in 2024 were cheaper than fossil fuel options.
These findings are supported by a United Nations multi-agency report stating that in 2024, wind, solar, and other clean power sources accounted for 74% of the growth in electricity generation worldwide. This rapid growth of renewables indicates a significant global trend toward clean energy investment and development.
Why it feels good
The new economic data underscores how renewable energy is transforming the global energy market, not just in environmental terms, but also in financial ones. United Nations Secretary General Antonio Guterres emphasized that this marks the dawn of a new energy era, one that is cheaper, cleaner, and abundant. This shift means better energy security, reduced dependency on volatile international fossil fuel markets, and improved economic opportunities for countries and communities alike.
Guterres highlighted that clean energy is smart business, pointing to the U.S.'s significant $2 trillion investment in green energy in the prior year, which far surpasses the $800 billion spent on fossil fuels. This investment trend shows how the world is aligning its money with sustainability, accelerating the transition to a greener future.
What to enjoy or watch next
With renewable energy costs dropping and investments rising, it’s exciting to watch how solar and wind power will expand further, driving innovation in clean technologies and reshaping energy infrastructures globally. Communities can look forward to more accessible and affordable green energy solutions that support both the planet and local economies.
For those interested in the environmental and economic impacts of clean energy, upcoming reports and research will provide deeper insights into how electric vehicles and other renewable technologies are helping to clear the air and reduce carbon emissions. Keeping an eye on these developments can inspire actions toward a cleaner, healthier planet.
