Quite !
Solar power as it is now, strikes me rather like electric hand-dryers - the triumph of the saleman over practicality.
Wind and wave have far greater possibilities - especially wind for individual properties.
More research into improving/radically redesigning the technology could well arrive at an answer. It is improving all the time as it is.
But there's more £/$ in building the monsters we see popping up all over.
And the lack of progress into wave or tidal power has always baffled me - a constant source of energy for translation into power.
The more materials and technology are improved or invented the more chance there will be - dare I suggest a more immediate pressing need than space travel, right now ?
