The world energy mafia, primarily petroleum, but also nuclear and coal, will not give up their revenue streams.
Carbon concentrations will continue to rise, and quite likely accelerate.
The overwhelming majority of sustainable generation is in large, regional scale projects, because this keeps the profit in the hands of the established energy utilities.
Nuclear... nuclear... I would pose a question to every bone head here who advocates it: Can we start storing the spent waste in YOUR garage?
The profit motive loves nuclear energy, because tax payers pay to build and decommission it, while industrial scale utilities get to operate it while money is popping out.
Nuclear is the most expensive form of electricity generation, by far. By very very far.
Distributed generation and storage is advocated by no one with an equity stake in the status quo.
The fundamental problem, is that the world economy is run by organized crime.
The US whitehouse has now made this explicit, however the situation has existed in this context since the invention of distributing petroleum and electricity.
