I have been waiting for this technology to catch on. My senior project for my BSEE at NJIT had been to develop a method to increase the efficiency of a PV cell. I had been researching the area of reflectivity and absorption as the vehicle to improve the efficiency of the cell. I am confident that the PV cells of the near future will enable the technology to be viable.

"lacks a suitable load-balancing solution" This is misleading, although true at face value, it is totally 100% wrong when considering that solar is a part of the total solution not the only solution. PV is actually very well matched to the AC component of the grid load, only 1-2 hours phase lead to the peak load times. PV will actually help to balance the total grid load, allowing large power plants to run more continues 24/7 at their peak effeceincies and minimum pollution output. hydro electric can be released at a more constant rate, minimizing impact on the environment and tourist industries where hydro is found.

I beg to differ with regards to the claim that "It is the only technology currently capable of meeting the world's long-term energy needs without emitting greenhouse gases". Windenergy is just as green as pv-generated energy. A windturbine with a rotor diameter of 5 m^2 produces (in light winds of 3-5 m/s) double to treble the amount of energy than a solar array of the same dimensions. Costwise, windenergy is a lot more efficient. Also, windturbines can operate at night. All future energy solutions will probably feature a hybrid structure, with wind and solar both contributing. So, give windenergy the credit it deserves.
