The recent frenzy in renew-able energy, particularly in the solar space, has raised expectations of coal-free, sunshine driven power for India at the lowest cost in about a decade’s time. The impetus for renewables is certainly the right step for coping with climate change challenges. However, we have to be realistic in our ambitions and base our plans on science and sound economics rather than hyperbole and rhetoric. Zero carbon renewables is the eventual goal, but in the foreseeable future coal seems to be the only option for reliable 24X7 power at less than ₹3 per unit. Solar and wind will be an increasing and growing complement to our conventional energy sources but is unlikely to be our primary source of power for quite some time.
