20. Actually, I'm a pretty big fan of solar, but not always PV.

For instance, there is MASSIVE energy savings to be had in solar thermal, heating household water on the rooftop. That is an ENORMOUS bang for your buck, and you couldn't achieve that same water heating via PV with battery storage, with 5x the surface area on the rooftop.

Then there is concentrating solar, another solar thermal solution. Expensive, but less expensive than, say, geothermal, with fewer side effects, and more wattage per square foot than large PV farms, if I recall the numbers right.

There IS a closing gap between PV efficiency and conservation that will continue to make PV a better proposition over time, but it has a long way to go before it's on-par with other renewables.
