Sorry, this should be under the heading of stupid polititicians not smart cities.
WOW - We can save energy if we know where we are using it? This has been going on in industry for at least 300 years (when some Scots started to work on thermodynamics to save fuel when making whiskey). That pipes leak has been known ever since the first pipe was made. That about half of the water put into a municipal water system could be leaking has been shown and published for at least 45 years, so any citiy that assumes they don't have leaks is just being stupid. We used odd/even license plates to ration who could buy gas in the 70's; It didn't work all that well then and it appearently doesn't work all that well in Bogota today (and really, how big a computer does it take to look at the plate?).
Should all these issues be addressed, yes of course, but is this being "smart"? Does it need the latest technology? No. The real questions are "why haven't cities been doing it all along?", and "how much better is the new measurement technology?"
