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.
