Wind, Solar, and the Fossil Dilemma: Global Energy in Flux

 The world is celebrating the remarkable rise of wind and solar energy in 2024. Yet headlines about historic clean energy capacity are matched by a sobering reality: fossil fuels are also at record highs. Instead of a straightforward shift from coal and oil to renewables, the global energy transition is a complex tale of growth, demand, and deep interdependencies.

Record-Breaking Growth for Wind and Solar

Wind and solar energy aren’t just trending—they are smashing records:

Solar and wind are not only expanding, but they’re also meeting most of the world’s new electricity demand. In 2024, renewable generation covered three-quarters of the growth in global electricity needs.

But Fossil Fuel Use Hits New Peaks

Despite all this progress, the world’s appetite for energy has outpaced even these breathtaking renewable gains:

  • Global energy demand rose 2% in 2024. dieselnet

  • Fossil fuel consumption reached an all-time high, up 1.5% to 505 exajoules, with coal, oil, and gas consumption each showing gains.

  • Fossil fuels still make up 81.5% of global energy consumption—a barely perceptible drop from 81.9% the year prior.

  • Energy-related emissions hit 40.8 gigatonnes of CO₂-equivalent, a new record, rising 1% versus 2023. carbonbrief

Why? Economic growth, population surges, and extreme weather spikes (like unrelenting heatwaves) all raised energy demand in 2024—particularly for air conditioning and cooling. Renewables supplied most of this additional demand, but so did coal and oil, which remain the backbone of many economies, especially in Asia and rapidly developing regions.

Why Renewables Aren't (Yet) Replacing Fossil Fuels

Power lines connect solar, wind, and traditional coal plants.

The global energy story is not a zero-sum game. Here’s why fossil fuels remain stubbornly persistent:

1. Demand Growth Outpaces Renewable Expansion

  • As societies modernize and urbanize, more people gain access to energy—driving up total consumption faster than renewables can replace existing fossil supply.

2. Grid and Storage Challenges

  • Integrating vast amounts of intermittent wind and solar requires smart grids and storage solutions. Without them, legacy fossil infrastructure often bridges the gap, especially during demand spikes.

3. Policy and Market Imbalances

  • Developed economies have plateaued in fossil use, but emerging giants like China and India are still expanding both renewables and coal to fuel economic growth.

  • Financial constraints, grid bottlenecks, and lagging policy reforms can deter rapid coal or oil phase-out, especially where jobs and economic security are on the line.

4. Hydro and Wind Variability

  • Even as installed capacity rises, real-world output can fluctuate with the weather. In 2024, lower wind speeds and unique climate challenges kept fossil backup in demand.

The Bright Side: Renewables Are Making a Dent

Not all is bleak. While total fossil fuel use grew, its share of overall energy slightly shrank. Some encouraging signs:

  • Clean power overtook 40% of global electricity in 2024 for the first time, thanks largely to new solar and wind projects.

  • Record annual additions mean that if current trends accelerate, renewables could meet a far greater portion of future energy demand.

  • Leaders in the G20 and global organizations are intensifying calls for “tripling” renewables by 2030—a goal within reach if expansion picks up just a bit more each year.

What Will It Take to Truly Shift the Balance?

1. Accelerate Renewable Deployment

  • The world is adding more wind and solar than ever, but to get on track for net-zero, we must sustain an average annual growth rate of 16.6% through 2030.

  • This calls for immediate investment—in new capacity, smarter grids, energy storage, and infrastructure upgrades.

2. Address Grid and Market Barriers

  • Modernizing electricity networks and redesigning market incentives are critical to integrate more renewables and push out coal and oil.

3. Global Equity and Just Transition

  • Transition planning must address regions and sectors dependent on fossil fuels for jobs and economic growth, prioritizing upskilling and targeted support.

4. Cross-sector Solutions

  • Electrify more sectors—like transport and heavy industry—using clean power, and invest in decarbonizing hard-to-abate processes.

Key Takeaways: Progress and Paradox

  • Wind and solar are surging, setting records yearly and supplying a substantive portion of new energy needs.

  • Global energy demand keeps rising—so much so that fossil fuel use is also breaking records, even as renewables flourish.

  • The transition is as much about social and economic systems as it is about technology.

  • The next phase will require not just building more renewables, but transforming how, where, and why we use energy.
