Cleantech could help cities save $17 trillion

Smart infrastructure choices from cities worldwide would save them $17 trillion (15.2 billion euros) by 2050. The solutions – renewable energy, public transportation, energy efficiency – are not new but the lens of this new study is interesting. 

Green and blue at the same time with Biosolar Roof

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… Continue reading The value of a well insulated home
