photovoltaics exist already -- but they are very inefficient converters of sunlight into electricity -- doesn't mean they aren't economic in some situations -- but the high capital cost limits the applicability -- also there is the energy required to manufacture them. The challenge remains for fuel cells -- which convert the chemical energy of H2 into electrical energy -- to find a cheap source of H2. Yes, air and water are plentiful, but it takes more energy to separate the H2 from these -- have to find a source where less energy input is required -- right now that means fossil fuels -- some other source is highly unlikely ... You make a good point, though, if there is another good energy source (in general) out there that we have missed the lead time to devlop it will be long -- that's why it is imperative that we start now on that and continue a push towards economic conservation and utilization of the resources that we have. My own personal view is that we are going to have to do with a little less convenience and more "appropriate" use of resources going forward.
