Executive Summary
Global primary energy consumption reached ~620 EJ in 2023 (≈ 19-20 TW average power), marking a record level. At the same time, renewables generated ~30% of global electricity, driven primarily by solar and wind growth.

The IEA projects that clean energy technologies – renewables, nuclear, and efficiency – will meet nearly all global electricity demand growth through the mid‑2030s, assuming strong grid expansion and flexibility markets.

In Europe, grid investment needs amount to ~€584 bn by 2030, with 108 GW additional cross‑border capacity by 2040 and 224 GW by 2050, plus ~540 GW storage. Each euro invested in transmission saves Europe more than €2 in total system costs.

EU industrial electricity prices remained more than twice US levels in 2024–2025, creating a structural competitiveness challenge.
[iea.org], [bruegel.org]
Global data‑centre power demand is expected to more than double to ~945 TWh by 2030, with Europe becoming one of the three global clusters; grid connection capacity is the main constraint.

Humanity’s Kardashev index stands at K≈0.72–0.73, and machine‑learning projections estimate ~0.745 by 2060-highlighting the fundamental role of energy, 😉 even if not relevant for near‑term policy.

Key Findings
Renewables Momentum, System Integration Bottleneck
Renewables supplied ~30% of global electricity in 2023, with solar contributing the largest share of new generation. 2024/2025 data show further increases in low‑carbon output, though heat‑wave peaks temporarily increased fossil generation in some regions. [ember-energy.org], [quoteddata.com]
The IEA expects clean energy to cover almost all demand growth through ~2035, contingent on accelerated grid expansion, energy storage, and demand‑side flexibility.

Grids as Strategic Value Creation
Europe’s Grid Action Plan highlights the need for faster permitting, anticipatory grid investments, and digitalised grid operations. Estimated investment requirements: ~€584 bn by 2030.
[eur-lex.europa.eu], [netzausbau.de]
ENTSO‑E’s TYNDP 2024 identifies:
- 108 GW additional cross‑border capacity by 2040,
- 224 GW by 2050,
- ~540 GW storage potential,
- >€2 system benefits for every euro invested in transmission.

Industrial Power Prices & Competitiveness
EU industrial electricity prices exceeded US prices by >2× in 2024/2025. In 2023 they were ~158% higher, largely due to import‑fuel exposure, network fees, taxes, and levies.
[iea.org], [bruegel.org]
European Commission data confirms that even with post‑crisis easing, non‑energy cost components remain elevated compared to pre‑2021 levels.

Data Centres & AI as Drivers of Grid Demand
The IEA forecasts data‑centre electricity consumption to exceed 945 TWh by 2030, more than doubling compared to 2024. Europe, the US, and China account for ~85% of global demand.

Grid bottlenecks, long connection queues, and the need for 24/7 carbon‑free procurement make data‑centre siting a power‑system decision, not just an economic one.
