re: What do you think the world would be like if it ran out of oil?

the world just goes back to wood burning steam power machines for everything industrial and power generating needs

NONE of these "green" power sources really work in any practical form. solar does the most to try to fill our needs and could charge batteries for night time lighting needs but beyond that its just not going to provide the level of power people use today. if you treated it like you had to to make due then it would be ok for household needs (no a/c systems) then people "could" get used to it, but to provide the power people use today if they want a/c systems running then every house will need a steam powered generator for making electricity
