Energy security is built with more than power plants and pipelines — it’s also built in the places where we live and work. When Europe’s buildings waste less energy, families are better protected from price shocks, industry becomes more competitive, and our energy system becomes harder to disrupt.

Europe’s building stock is a vital factor in building energy independence 

Almost 60 percent of the EU’s primary energy is still dependent on fossil fuel imports. The fastest way to reduce that exposure is not to replace one fuel with another — it’s to reduce the amount of energy Europe needs in the first place. Energy efficiency turns energy security into something we can benefit from immediately, building by building: less wasted energy, lower demand, and fewer imports required to keep homes warm and businesses running.

Today, three out of four buildings in Europe are energy inefficient, meaning a significant portion of Europe’s current consumption ends as energy waste. The consequences are already visible:

  • Demand peaks drive up energy prices that impact families and industrial competitiveness
  • Strain on electricity grids increases the risk of disruptions
  • Grid congestion slows down renewables and the wider transition

Without deep improvements in building efficiency, Europe risks shifting dependency and volatility from imported fuels to an overstretched power system. Efficiency first reduces the problem at the source — making electrification more feasible, affordable and secure.

The case for energy efficient buildings 

Efficient and flexible buildings in an electrified system could lower peak demand by almost 50 percent by 2050, delivering:

  • 312 BEUR saved annually compared to decarbonising at today's renovation rate
  • 44.2 BEUR optimised annually in distribution grid investments
  • 50 percent average reduction in energy bills across Europe
  • Lower electricity costs for European industry, boosting competitiveness

In practice, this means fewer extreme peaks, less stress on networks, and a more stable system that can absorb renewables and electrification at pace.
