That's so incoherent it's no wonder you provide no evidence attempting to support it. But never let clarity stop you.. Efficiency you say? An array of solar panels converts free sunlight immediately and directly into substantial electrical power. In terms of creating shaft power you can probably only get more "efficient" with a wind turbine. But, like fossil fuels, the wind itself is a byproduct of sunlight. An installed solar panel requires no gasoline, lubrication, gas can, walk to a gas station, special bridge/highway, tanker ride, pipeline, permanent federal subsidy, drilling, blasting, enormous storage tank, scrubber, ... and on,.. and on... But, clearly you two are shameless, clueless, or both.
