Hybrid cars are excellent, using fuel on faster roads and batteries in urban driving, to keep localised pollutants like NO2 away from children.
Natural gas is the cheapest, most efficient, cleanest way to generate electricity; use it 'til it's done.
Coal scrubbers can eliminate much of the pollution caused by coal generation, invest in r&d in this area.
Fracking will give us clean hydrocarbon power for centuries.
Being taught how to eliminate wasteful usage saves money, as do aforementioned insulation, efficient. lean burn, systems, etc.
Note I don't count CO2 as pollution, because it isn't.
