Insulating a home does not give you a 50% reduction! It's closer to 15%.
You might get 50% on a leaky barn with zero insulation, but how many homes in Europe are like that?
(Note I'm not saying not to do this - certainly do this, just have proper expectations.)
- bombcar 4y agoProper perfect brand new construction compared to 1950s worn out building might be 50% increase but that requires building a new building. Add-on insulation can help but it’s much harder and not as great.
- radicalbyte 4y agoI achieved a 50% heating cost reduction after investing in the insulation of an older house. This included replacing the single pane glass. Such properties are common over Europe; especially in properties built before the 1980s (which thank to the rebuild after WW2 are a decent percentage of all building stock). Overall you'll maybe cut gas usage by 20% in 2-3 of years by insulating those buildings, building out renewable electricity with storage and incentivising heat pumps (which reduce/remove gas usage of resident-owned properties where they are viable).
