I learned by now that the power consumption is NOT per day, but for the total of 42 days it is used.

Before there were 25 000 bulbs, 7.5 W each (in 1949 it were 7500 bulbs) ->
187 500 Watt. These are more reasonable numbers (75 kWh a day, 10 hours a day, 42 days) - and a bill of $130 only for electricity. (how much is a kWh in the USA? I assumed 0.1 $/kWh)

We had an article in the local paper today about this. the tree is lit all day every day from 530am to 1130pm. tourist season you know. so it's lit a lot more hours than your would have expected. they also had the key cut down by hand instead of using chainsaws and are giving the lubmer from the tree to habitat for humanity to build homes when the season is over. even if it's a political statement i think the goal is to encourage the manhattan population to go a little greener in lifestyle.
