By 2030 solar energy will have the capacity to meet all of our energy needs. The production of food and clean water will also be revolutionized.

If we could capture one part in ten thousand of the sunlight that falls on the Earth we could meet 100% of our energy needs, using this renewable and environmentally friendly source.
As we apply new molecular scale technologies to solar panels, the cost per watt is coming down rapidly. Already Deutsche Bank, in a recent report, wrote “The cost of unsubsidized solar power is about the same as the cost of electricity from the grid in India and Italy. By 2014 even more countries will achieve solar ‘grid parity.’”
The total number of watts of electricity produced by solar energy is growing exponentially, doubling every two years. It is now less than seven doublings from 100%.
Similar approaches will address other resource needs. Once we have inexpensive energy we can readily and inexpensively convert the vast amount of dirty and salinated water we have on the planet to usable water.
