They are more than likely just trying to lower the overall power sink that the city pulls as it grows. Obviously the massive buildings and projects are going to be using a shit-ton of power and I don't know where dubai gets its power from - but it is most likely limited... so this is a good thing for that infrastructure.

I have a friend who lives in dubai, Ill ask her about where their power comes from as well..

I wonder how many datacenters are in dubai.

We bought a new house this year, and replaced all the lights with LED lights - and our power bill is really low.

in 2001 when the Enron fiasco happened, I received a power bill for $900 for one month, and my usage behavior didn't change from previous months. It was during the dot com crash and I wasn't working - and I couldnt pay the bill had my power shut off and had to borrow money from my parents to pay the criminals.

So I am very power conscious...
