It will substantially reduce the carbon footprint and have a favourable impact on the trade balance. But the engineering problems associated with 1-1-1 are formidable. There are challenges of scale, challenges in adopting many new technologies, and challenges in working out distribution chains and storage systems. If those are met, there would be a big payoff, given
