Alternative Fuels
Air pollution is most commonly associated with acidic
precipitation, smog, and the depletion of our ozone layer.
Acid rain is one of the biggest air quality problems that
upstate New York deals with, especially the Adirondack
Mountains. The main cause of acidic rain is the emissions of
gases like SO2 and NOx These emissions are given off into the
environment mostly from the burning of fossil fuels, either
in vehicles or in industrial buildings. The best way that you
can combat such a problem would be to find alternative
ways to obtain energy, or by finding alternative fuels that
can be combusted, yet give off less harmful emissions into
the environment.
The concept of alternative fuels has been around for
many years. Since the Clean Air Act was passed, there have
been numerous efforts to find different fuels that can be
burnt instead of gasoline, which produces many
environmentally harmful emissions. These alternative fuels
include alcohols, electricity, natural gas, and propane. In
general, these alternative fuels, or clean fuels,reduce the
level of emissions that cause ground-level ozone (which
leads to smog), and of hydrocarbons, which lead to ozone
layer depletion.
Vehicles that use electricity as their main power source
tend to be virtually pollution-free, which makes them one of
the best alternatives for reducing harmful vehicle
emissions.
