...energy efficiency of new buildings has improved, and emissions per square metre have been reduced. However, we replace our building stock in Europe very slowly, at less than 1% per year. This means over 80% of our existing building stock will still be standing in 2050. Regulation on the whole still ignores embodied carbon impacts (although this has recently been debated...

...energy, thanks to E = mc²) follow these straight paths in curved space. The experimental proof of this occurred during a solar eclipse in 1919 where starlight was observed to be bent by the sun. The amount of bending was predicted by Einstein, and not by the standard “Newtonian” theory. So matter follows the curvature of space, but we know matter is the source of...
