Total estimated energy potential for renewables in the US (wind/solar/biomass/etc) is 481800 TWh. The US used 25,776 Twh of energy in 2010. That's a lot of renewable energy. With that much renewable energy, you can desal all the water you want. You could even replenish aquifers by condensing water out of the air when power is cheap (at night, when the wind is blowing hard).
We have enough land for food production, which is for the most part automated (http://www.epa.gov/oecaagct/ag101/demographics.html ; "There are over 313,000,000 people living in the United States. Of that population, less than 1% claim farming as an occupation (and about 2% actually live on farms). In 2007, only 45% of farmers claimed farming as their principal occupation and a similar number of farmers claiming some other principal occupation. The number of farms in the U.S. stands at about 2.2 million."). As we continue to automate farming, we'll be able to feed more people with less effort. Ergo, there is enough food for everyone.
So, let me run through this:
* Energy
* Water
* Food
* Communications infrastructure
Ahh! Transportation! I missed that. Self-driving electric cars fit the bill. Also, efficient traffic management algorithms ensure our existing roadways can be used at maximum efficiency, thereby removing the need for more roadway.

Did I miss anything?
