AUTONEWS



New York will delete it for good mineral coal in 2020

Electric vehicles only make sense if the energy that drives them is generated by less (or less) polluting means. Generating electricity from coal is a mistake that, in the limit, can remove pollution from the center of cities, but does nothing in relation to global emissions.
This is due to the fact that it is not enough for manufacturers to produce their electric vehicles on batteries or hydrogen fuel cells in order to reduce CO2, NOx and particulate matter, as well as sulfur and many other deleterious elements. It is also necessary for countries to produce the energy they need to feed industry, businesses and households with less (or, ideally, no) pollutants.
Without renewable energy, or hydrogen produced without the use of petroleum derivatives or carbon-containing gases or alcohols, it makes little sense to continue to sacrifice car manufacturers and users. Hence the state of New York has announced that by the end of 2020 it will switch to producing electricity without recourse to coal, arguably the most polluting way of generating energy.
The ruling by US lawmakers stemmed from a regulation, effective June 8, which sets emissions limits that make it impossible to use coal as a source of energy. And this battle against coal is not new to the New York state, as today only only 1% of electricity is generated using this product. Nonetheless, it is yet another step towards generating energy using renewable sources, all to cut 40% of greenhouse gases from electricity producers by 2030.
It should be recalled that New York recently passed a law requiring larger buildings to reduce their carbon dioxide emissions by 40 per cent by 2030 and by 80 per cent by 2050. This measure, which involves the energy expended in heating and lighting, is the first that involves a large city.
