If there was one ultimate energy source to break the world’s addiction to fossil fuels, expert Robert Hirsch says the world would be using it by now.
While wind turbines and solar panels remain the popular symbols of a future clean-energy economy, scientists and engineers are busy cooking up a plethora of new technologies to save and produce energy.
Finding alternatives to climate-damaging oil and coal energy is all about diversification. None of the proposed "climate solutions" could stabilize greenhouse gas emissions or meet the world's energy demands alone. But taken together, they could be important pieces of the puzzle.
