Electricity is made using coal. Coal is extracted by machines, which run on fuels made from oil. These machines have plastic parts, made from oil. The coal is transported in trucks, which run on fuel made from oil. Oil is gonna be in the chain somewhere.
Bit simplistic, but correct as far as I can see.
Sorry cook$
Hydroelectricity
Wind turbines - produce electricity
Wave power can be harnessed to produce electricity
Solar panels.
Unfortunately your wrong on that one. Makes a change i know. But yes your right somewhere along the line oil is involved. The only thing possible is that we produce enough electricity producing instruments before the oil runs out, if we dont then your argument stands.
Its a kinda catch 22 situation.
And to those saying geothermal - thats brilliant - if your in an area where geothermal activity takes place - which lets face it - unless you drill far enough down (pretty dam hard and stupidly expensive) is in very few areas.
