Electric/hybrid cars are NOT the answer
Basic Physics (Fleming's left and right hand rules) should indicate to anyone the wasteful nature of generating electricity from raw fuels, and then using that electricity to generate motion. Optimistic calculations give the overall energy transfer rate for these two processes to be 10%. Electric powered motion only makes sense with mass transport - trams and trains - and for reducing LOCAL pollution (i.e. within a town). The overall pollution, and global warming due to energy use (which nearly always ends up as heat), rises overall in all cases.
The best way to reduce energy loss is to use mass transport, or individual transport (i.e. a bike or a motorcycle, where you only cart around enough "deadweight" to carry yourself). In terms of energy used per passenger (the best comparison), my diesel Long Wheel Base Land Rover when carrying my whole family (7 of us) beats a hybrid car carrying one person.
