> How much pollution is too much? I feel we are a long way from that point still, in India. I would argue: any pollution that isn't factored into the cost of the energy production. If it's not priced in then there's no rational acting in the market, which (for better or worse) is the mechanism that we're using to figure out which energy systems to deploy. Even with that in mind, renewables like solar and wind are already easily cost-competitive with coal in many locations and getting more so every day (by most current measures of levelised cost of energy).
