The quote below is a typical example of many that can be found describing the air quality in Delhi. Surely it makes no sense to add more coal pollution to a bad situation when building new power infrastructure especially when renewables are now cheaper.

The air quality index touched the “severe” category in the first week of November, hitting 448 on a scale of 500 for the second time this year.

Several studies and government committees have highlighted that burning coal, petrol, diesel, gas, biomass and waste, along with industries, power plants, and firecrackers are major contributors of pollution.
