Promoting energy efficiencies

Boosting energy independence and cutting greenhouse gas emissions

Seaside city at night, with lots of city lights shining into the water.

How can the  European Union reduce at least 55% of its CO2 emissions by 2030? The most obvious answer is to use less energy in the first place.

Buildings alone account for 40% of the energy consumption in Europe. By renovating older buildings and making energy grids more efficient, there is scope for reducing emissions, becoming more fuel self-sufficient, and cutting energy bills while still keeping people warm. 

Note: This page features projects focused on the energy efficiency of buildings and energy grids. Projects focused on the circular economy or green transport also contribute to saving energy.
