It is not easy, to be able to face a problem as big as pollution, it is necessary the willingness of different public and private sectors to face the causes of it, in the case of India that has reached such critical levels, it is necessary that the government and each citizen understand that each of their actions are responsible for that. And that in their hands is the power to correct it.
There are simple solutions that the citizen can do, how to use public transport, recycle, avoid excessive consumerism, among others. Also the Create and apply (this last is the most important) environmental laws that prevent that polluting is more lucrative than not doing it.
It is a state of emergency situation and I think that it may require a multitude of interventions starting with the residents.
But it is still a problem in the way we think, as it is possible that existing technology for the manufacture of electric cars, but so far that is investing in that sector, or that in Spain for example there is the so-called tax to the sun "Impuesto al Sol", that is, if my house uses renewable energy, I must pay a tax that is more expensive than paying an electric company. (which personally I think it does not make sense)
That is why I say that governments, companies and citizens should want to solve the problem
I enjoy our dialogues. Yes, renewable energy has been a hot topic for decades and considerable more efforts need to make it an affordable option. Everything from the cost/use of windmills, water, solar to harness energy continue to cost more than standard methods. An electric car costs more than a gas fueled vehicle and never mind the cost of repairing it if something goes wrong.
