Opponents of wind and solar are falling back to the second line of defense... Sadly led be Jim Hansen... who really needs to stick to climate science... claims that wind and solar can't possibly meet our growing energy demand are coming out of the woodwork. At the lay level acceptance of this myth appears to be at least partially driven by confusion over power and energy. A co-worker (With a degree in physics) once asked, 'What good is a 10kW solar array if I use 1500kWh/mo?' ....... !?!?!?...... what?.... well... for starters a 10kW array produces ~1800kWh/mo... The main issue with wind and solar is intermittency not energy. As the costs of storage approaches $100/kWh the intermittent nature of wind and solar will be less and less of a problem.
