Data and insights
Every country has a different energy mix and building stock with its own specificities. In some cases, such as in the phasing out of coal or in regions with old buildings, gases will play a particularly important role. Where there is a gas connection, and supply can be decarbonised, this is often the right way to go. There is also a risk that we could slow down the transition for buildings by counting too much on electrification, as electricity network reinforcements could take decades to complete. Switching between energy vectors for home heating can be costly, sometimes involving cumbersome renovations. In some old buildings, it would not even be feasible. In these cases, lending, district heating, hydrogen-ready boilers, CHP and fuel cells can all play a role in the cost-effective decarbonisation of buildings. These technologies offer potential job creation and, crucially, will help meet energy needs across different regions, communities and socioeconomic groups.
