The pace of change toward cleaner, more sustainable energy is accelerating and a new report from the International Energy Agency (IEA) offers encouraging news.
According to the IEA, the world’s renewable power capacity is on track to double by 2030, signalling a powerful move away from fossil fuels and toward a more sustainable, secure and affordable energy future.
Solar Energy Leads the Charge
The IEA report predicts approximately 80% of all new renewable capacity will come from solar power, with the rest coming from wind, hydropower, bioenergy and geothermal energy.
In more than 80% of the countries around the world, renewables will grow more in the next five years than they have in the last five.
Challenges
Despite the incredible momentum, the report also highlights several challenges that could slow progress. Integrating huge amounts of new renewable power into existing grids is a major technical hurdle and financing projects can become tricky when policies shift.
For example, in the United States, some recent changes such as the early phase-out of tax credits, new import restrictions and the suspension of new offshore wind leasing are creating uncertainty for developers. Similar policy and supply chain issues are being felt elsewhere, too.
Drivers
Still, the outlook remains positive. The report points to strong forces driving renewable energy forward:
- Falling costs – Solar panels and related equipment are now cheaper than ever.
- Supportive contracts – Power Purchase Agreements (PPAs) and utility partnerships are expanding.
- Streamlined approvals – Fast-track planning policies are helping projects move more quickly.
- Public enthusiasm – Communities around the world are embracing renewable energy projects more than ever before as they see more solar and wind developments are installed.
Together, these trends are helping clean energy move from ambitious targets to real, tangible progress.
Wind Energy: Strong Growth, but Facing Headwinds
Unlike solar, rising costs, permitting delays and supply chain bottlenecks are slowing development of wind power but still it is on track to double globally by 2030.
Offshore wind, in particular, has encountered policy and cost challenges from the United States to Europe, Japan and India but even so, wind remains an essential part of the renewable mix, helping diversify global energy systems and support grid stability.
Economic Payoff of Going Green
The economic story behind renewables is powerful. As solar and wind capacity grow, some regions are experiencing periods of negative electricity prices meaning supply is so abundant that wholesale prices temporarily dip below zero.
Beyond that, the global shift to renewables has dramatically reduced fuel imports. Since 2010, the world has:
- Cut coal imports by 700 million tonnes
- Reduced natural gas imports by 400 billion cubic metres
That’s an enormous win for the planet.
Electric Vehicles Drive Change Too
Renewables aren’t just powering homes and cities they’re also fuelling a transportation revolution. The IEA report notes that electric vehicles (EVs) account for half of the recent growth in renewable electricity use, particularly across China and Europe moving us closer to a decarbonized future.
A Brighter, Cleaner Energy Future
The IEA forecasts a new era of transformation with the world is steadily moving toward a cleaner energy future.
By 2030, solar and wind could together define the backbone of our global power system. The shift isn’t just about energy it’s about innovation and cooperation,. Every new solar panel, every wind turbine, and every EV represents progress toward a healthier planet.
