Conservation of Fossil Fuels

Fossil fuels are non-renewable (once used, gone for millions of years). At current rates: known petroleum reserves may last ~50 more years! Problems: air pollution, greenhouse effect, acid rain, oil spills. Conservation: use public transport, share rides, turn off lights, use LED bulbs, renewable energy (solar, wind). India's National Solar Mission aims for 100 GW solar by 2022.
