I have to agree it's been a great springboard and we should be doing more. I think the reality on the ground is that solar has only achieved attractive efficiency levels in most recent years. Similarly electric vehicle range and cost has only started to become achievable in recent years. Right or wrong nuclear has always had a perception of danger to it that the most people would say NIMBY. It's understandable there is still a thriving market in the developed world for petroleum fuels. I think we've finally reached a point now were the market is offering both individual and larger scale commercial/public energy solutions. It takes time for new infrastructure investment - it's lots of small efforts. Given the reality on the ground in most of the developed world I have to imagine it takes another 50 years to get to majority renewables. So what's a petroleum producing world power to do? Seems like ensuring a balance of power and energy production for the next 50 years of world development is a responsible thing to do.
