Europe can achieve clean power by 2035 at no extra cost

22 Jun 2022

Wind and solar become the backbone

Across all least-cost pathways modelled, wind and solar provide 70-80% of electricity generation by 2035. To achieve this, annual growth in wind and solar deployment must quadruple compared to the last decade, averaging 100-165 GW per year over 2025-2035. 

  • Solar capacity grows by up to 9 times, reaching as much as 1400 GW
  • Wind capacity quadruples in size by 2035, reaching 800 GW

The modelling shows how clean power systems deliver security of supply even during challenging ‘dunkelflaute’ conditions, where a harsh cold spell coincides with prolonged low wind and solar output. Three key technologies emerge as the cornerstones of flexibility: electricity interconnections double and hydrogen electrolysers hit 200-400GW by 2035, supported by clean dispatchable sources that can be called upon when required (e.g., hydro or low-emission gases). New nuclear capacity is not a feature of least-cost pathways, but the analysis also finds that current expansion plans across Europe do not incur significantly higher system costs.

Scaling clean power is a win-win-win. It will save money, put Europe on track for its climate commitments and reduce its reliance on imported fossil fuels. Europe should invest now for a huge payback by 2035.

It’s time for Europe to roll up its sleeves. Europe has shown it can step up its ambition in the face of the gas crisis and Putin’s fossil-fueled war. It is now required to keep pushing forward, to avert the climate crisis and unlock countless benefits for citizens and businesses.

Decarbonising the energy sector now is consistently demonstrated as more cost-effective than sustaining fossil fuels and assuming mitigation measures down the line. Solar is the kingpin of the clean electrification wave, and together with flexible storage and grids, solar can provide reliable electricity at all times – at the lowest levelized cost of electricity of all energy sources.

Minimal role for fossil gas – and coal is quickly gone

The models reveal that coal must be phased out by 2030 and unabated gas reduced to less than 5% of generation by 2035 to make Europe’s power system fit for the Paris Agreement. No large fossil gas plants need to be commissioned beyond those expected by 2025. 

If the full potential of electrification and energy savings can be realised, Europe’s total consumption of fossil fuels would halve by 2030. At the EU level, the modelled clean power pathways represent a greater reduction in fossil fuels than the REPowerEU plan, although they are less targeted at reducing fossil gas.

On wind and solar, the REPowerEU plan moves the EU-27 closer to the modelled pathways to 2035 clean power, but major challenges remain in translating this into European and national policy and deploying the infrastructure on the ground.

Methodology

This study explores the least-cost pathways to a clean power system in Europe, compatible with the Paris Agreement climate goals (1.5C).

Detailed, country-by-country, hour-by-hour power system modelling confirms the feasibility of almost completely decarbonising Europe’s power sector by 2035, while expanding the electricity supply. Key metrics are calculated in order to quantify and track progress, while accounting for a range of uncertainties. Crucially, the costs of competing routes are assessed, including the costs of developing the power system according to current plans.

This report summarises the results of three modelled pathways for the European power sector. The Stated Policy pathway is aligned with stated national policies until 2035. The two clean pathways – Technology Driven and System Change – are computed to minimise cost while remaining within a carbon budget compatible with the Paris Agreement climate goals. The latter two pathways expand clean electrification, but differ in their assumptions about available technologies and the levels of energy savings resulting from societal change.
