E.g. in EU households, heating and hot water alone account for 79% of total final energy use. 84% of heating and cooling is still generated from fossil fuels while only 16% is generated from renewable energy sources. Around 70% of the EU population lives in privately owned residential buildings.
This HWG supports 100% renewable energy (RE) in existing and new individually heated & cooled buildings (residential and others) that are difficult to connect to district heating and cooling (DHC) grids, e.g. due to either its remoteness (in rural areas), or due to its low energy demand (new, low-energy buildings or passive houses).
Key challenges today are the low fuel prices of heating oil and natural gas, high initial investment costs for RE systems, insufficient consulting expertise on RE systems of key actors, lack of awareness and information, as well as the complexity of combined RE technologies.
