Fascinating and detailed piece in the Wall Street Journal: How to Build a Greener City
From the piece:
If the current rate of urbanization holds steady, cities will account for nearly three-quarters of the world’s energy demand by 2030. Most of the increase will come in rapidly developing countries like China and India; China’s cities alone will have to deliver water, housing, transportation and other services to 400 million additional urban dwellers by 2030.
So, cities aren’t going to have be made a little greener; they’re going to have to be rethought from the ground up.
The piece covers some fascinating — and sometimes technical — issues, including district heating, micro wind turbines and micro hydropower, and pneumatic garbage collection.
There is much more in the piece.
