While browsing Cleantechnica I found the answer of a key question I have been having ever since writing my Master’s thesis. French houses are leaky ” thermal collanders “ as 20 million accommodations have to be weatherized.
Potential savings could be the equivalent of 200 TWh of electricity per annum, knowing that the total electricity consumption in France is of 473 TWh. I had been wondering if this was the case in other countries.
But given this brilliant article, French dwellings aren’t the only one to be vastly inefficient. as similar data are mentioned : old houses need 300 kWh per square meter per year.
