Environmentally friendly?

I never thought anyone would link online gambling to being environmentally friendly.  I am going to do it though!  I started thinking that casinos are just big buildings using a ton of energy to run 24 hours a day, and they are filled with smoke and other things that increase your carbon footprint.  So why not say that the online casinos are better for the environment.  You don't need the large brick and mortar building where the smokers congregate, they can stay at home and gamble until their hearts content online.  They don't have to drive cars to get to the casino, the electricity used at home should be far less than that of a thousand slot machines  spinning and clanking spitting out tokens.  There are no neon lights at the online casino, and no air conditioning used.  There needs to be no air purification system in place, and well the online gambler can play in the dark.  So if there is any link between online casinos and the environment I will find it.  All we need to do is get the online gambling sites to use green energy to power their servers and we will be all set.  I think it is a new niche of the online market, any one want to take the bull by the horns?
