Enumerate the ways by which acid rain can be controlled to prevent it's adverse effects on the environment.

Ways to control acid rain:

1. Using alternate energy sources - alternatives to burning of fossil fuels such as compressed natural gas [C.N.G.] or use of cleaner energy sources such as hydro power or wind energy causes almost no pollution.
2. Usage of technical devices - such as catalytic convertors, which can reduce nitrogen oxide emissions from automobiles [usage of electrostatic precipitators in industries].
