India’s next green revolution

about the climate a crucial question is how emerging economies, which accounted for 67% of carbon-dioxide emissions from energy last year, can shift to a cleaner approach. They derive a third of their primary energy from coal, and must meet the aspirations of poor citizens who lack cheap electricity.China offers one template: its energy industry is shifting towards renewables. Yet it is still moving far too slowly to reduce its emissions and many countries may be wary of replicating its state-led approach. An alternative model is now visible in the other Asian giant, India, which is in the led by the private sector. Although it has obvious flaws, it provides hope that India can make the green leap.
