Because these are so reliant upon political capital, the biggest impediment to these things is public opinion. The problem here is that the bar is unreasonably high. If the solution doesn't solve climate change, it's useless. The bar isn't the status quo, which is going to kill off humans. But our solutions will never work like that. Short of not existing, the human race at the scale at which we exist will always have an impact. It's about decreasing and minimizing the impact at incremental, evolutionary levels, rather than "solving" climate change. Point being, this is good, but we'd be better off if we could just build on-shore wind farms. But...NIMBY, and an impossible bar.
