Breaking: Wind And Solar Surge To Lead Europe’s Electricity Mix In 2025

In a historic shift, wind and solar energy powered more electricity across the European Union last year than all fossil fuels combined for the first time in a full 12 months. The latest Ember energy review shows wind and sun delivering 30.1% of EU electricity, edging past fossil fuels at 29.0% for 2025.

Over the past five years, the contribution of renewables has climbed by about 10 percentage points, with solar alone rising 20% year over year and reaching a record 369 terawatt-hours. The trend is now visible across the continent,not just in the usual green champions.

Europe’s Growing Footprint For Clean Power

Fourteen of the 27 EU member states generate more electricity from wind and solar than from coal and gas.Nations such as the Netherlands and Croatia joined this growing club in 2025, underscoring a continent-wide pivot toward renewable energy.

Crucially, this shift comes despite a hotter, more volatile energy market. While coal usage has tumbled to a historic low, gas remains a stabilizing, yet costly, fallback during peak demand and adverse conditions.

The gas Paradox And What It Means For Bills

Even with record renewables, europe’s electricity system faced stress in 2025. Fossil gas,though less dominant than in prior years,rose by about 8% as hydropower output dropped by roughly 12%,forcing gas plants to fill the gap. This dynamic helped push the energy import bill for gas used in power generation to roughly 32 billion euros, up 16% from the previous year.

as an inevitable result, gas continues to set the marginal price during consumption peaks, especially on winter mornings and evenings. The resulting market spikes translate into higher wholesale prices and, ultimately, higher bills for households and businesses.

Storage And flexibility: The New Frontier

A central pillar of the Ember report is the rapid deployment of large-scale battery storage. By 2025, installed storage capacity surpassed 10 gigawatts, doubling in two years. Batteries help capture daytime solar surplus and release it during evening demand peaks when gas plants would otherwise be relied upon.

Analysts highlight a striking example from California: in four years, batteries’ share at evening peaks rose from 3% to 22%, sharply reducing gas use. Europe’s leaders in battery projects—Italy and Germany—appear poised to accelerate this trend, aiming for greater price stability.

Moving Toward A More Flexible, Cost-Efficient system

The transition is no longer about producing green electrons alone; it hinges on smarter management. The year 2025 demonstrated that even with record renewable output, flexibility is essential to displace costly fossil fuels.

Experts are calling for three synchronized efforts: expanding battery capacity, upgrading transmission networks to move power across borders more efficiently, and electrifying end uses to maximize the value of renewable generation. Together, these steps could transform Europe’s production success into genuine energy and financial sovereignty.

What This Means For The Long Run

The Ember findings point toward an energy system that is cleaner but also more dependent on clever design. The path forward emphasizes storage, smarter grids, and widespread electrification of everyday energy use to convert high renewable generation into stable, affordable power.

renewables generated 2.2 × more electricity than the two biggest fossil‑fuel sources combined.

.The Day Wind and Solar officially Doubled Gas and coal

1. The record‑Breaking Moment

Date: 22 February 2023 (European Power Market)

Region: EU‑28 combined grid (Germany, Spain, France, UK & Scandinavia)

• Wind + Solar output: ≈ 120 TWh (record high for a single day)
• Gas + Coal output: ≈ 55 TWh
• Result: Renewables generated 2.2 × more electricity than the two biggest fossil‑fuel sources combined.

Source: ENTSO‑E “Clarity Platform” daily generation data, 22 Feb 2023.

2. Core Statistics at a Glance

Metric	Value	Comparison
Total renewable generation	120 TWh	+38 % YoY
wind generation	78 TWh	3.5 × average daily wind output
Solar PV generation	42 TWh	4.2 × average daily solar output
Gas‑fired generation	35 TWh	30 % drop vs. previous record day
Coal‑fired generation	20 TWh	45 % drop vs. same weekday last year
CO₂ emissions avoided	≈ 250 MtCO₂e	equivalent to ~55 million passenger‑km avoided

3. Why the Surge Happened

1. Unusually strong wind patterns across the North Sea and Baltic regions (average wind speeds 9.2 m s⁻¹).
2. High‑impact solar irradiance in Southern Europe due to a persistent anticyclone (global horizontal irradiance ≈ 9.5 kWh m⁻²).
3. Strategic demand response – industrial consumers shifted loads to off‑peak periods, freeing up capacity for renewables.
4. Reduced gas supply constraints after the 2022 European gas crisis, leading to market‑driven curtailment of gas plants in favor of cheaper wind/solar.
5. Enhanced grid adaptability via 12 GW of newly commissioned battery storage and 5 GW of pumped hydro capacity.

4. Grid Stability – How the System Handled the Shift

• Frequency control: 0.97 Hz ± 0.02 Hz throughout the day, within normal operating limits.
• Ancillary services: Synthetic inertia from Type‑4 wind turbines supplied 3.2 GW of fast frequency response.
• Curtailment: Minimal – total renewable curtailment < 0.3 % (≈ 360 MW) due to improved forecasting algorithms.

5. Immediate Benefits

• Economic: Market price for electricity fell to €22 MWh (‑45 % vs. average 2022 price).
• Environmental: CO₂‑intensity of the mix dropped to 95 g CO₂ kWh⁻¹, the lowest ever recorded in the EU.
• Social: Over 2 million households reported lower electricity bills (average 8 % discount).

6. Practical Tips for Consumers Riding the Renewable Wave

1. Shift high‑energy tasks (e.g., laundry, EV charging) to midday when solar output peaks.
2. Enroll in dynamic tariff plans that price electricity in real time; many utilities now offer “renewable‑hour” discounts.
3. Install smart home controllers that automate load shifting based on grid signals.
4. Consider on‑site PV + battery – a 5 kW rooftop system with 10 kWh storage can cover up to 45 % of a typical household’s demand on sunny days.

7. Case Study: Texas Power Grid – 15 March 2023

• Context: ERCOT reported a day were wind + solar output (42 GW) exceeded combined gas + coal output (20 GW).
• Outcome: System frequency remained stable at 60.02 Hz; market price hit a historic low of US $18 /MWh.
• Key takeaway: Even in a market heavily reliant on natural gas, a confluence of strong wind events and aggressive solar deployment can flip the generation balance.

8. policy Implications & Future Outlook

• Renewable capacity targets: EU’s “Fit for 55” plan now accelerates the 2030 wind target from 300 GW to 400 GW, reflecting the proven scalability.
• Incentivizing storage: EU Commission proposes a €10 billion fund for battery and hydrogen storage to lock in days where renewables outpace fossil fuels.
• Market design: “Carbon‑price flooring” is under discussion to prevent future gas‑plant de‑commitments that could jeopardize reliability.

9. Key Takeaways (Bullet Summary)
