If you stop using fossil fuel today, civilisation will fall, billions will starve, fossil fuel is a limited source so we need time to develop tech which is capable of supporting us all while slowing moving to sustainable means.
Slowly, there is no rush or panic at the moment!
Oil demand is pretty low, so reduced co2 output and heat pollution should make for a cold winter and colder 2015.
No hurry at all? You may want to consult farmers and fishermen about that. Or anybody that doesn't live in a city (except for those mining coal).
