I'd like to make this chandelier:

But before I embark on this quest I've few questions.
Cleverly titled "edison chandelier", this thing has 10 incandescent bulbs so energy consumption will be over the board with approx: 10*60w=600w. More than half of my houses total consumption at any given moment. What can I replace this with? Are there economy version of these bulbs? Transparent LED imitation of edisons bulb or something?
How do I choose a wire?
How do I connect wires at the base?
What about using arduino with wifi shield to wirelessly shut of portions of the lamp?
