Venus Project

Zeitgeist 2 mentions the Venus Project which proposes the world can be run on solar, wind, tidal and geothermal power, with electric cars and maglev trains for transportation, and unlimited abundance of food, shelter and basic needs by eliminating scarcity.  Technology would handle 90% of labor, while technology itself improves to be more and more efficient because it won't rely on money or competition, but instead payment will consist of warm happy thoughts and paintings. 

So what are some flaws in the idea that there is enough energy, food, and advanced technology for everyone in a society relying on resource and energy abundance without using money as a competitive incentive?  Could Intel create better CPUs by being paid in happy thoughts?

That may be true with contemporary technologies, but with experimental solar panels reaching over 80% efficiency, you could very well power the world with solar panels.
Conventional panels are efficient anywhere from 12 to 30 percent, and they collect enough energy to power a home, and in some cases have enough power left over to be sold back onto the grid.
This is further supported with research into infrared solar cells, which allow the capture of energy well after the sun has set.
The cost per watt may be great now, but the more they are produced and put into use, the cheaper they became, especially when they end up paying for themselves in electricity bills (or lack thereof). This, coupled with the every growing fossil fuel costs, makes solar cells a real challenge for fossil fueled energy production.
