I will admit that 4 years is not better than 6 months, but you are talking about production costs of oil. What about transportation and refinement? There are so much more costs involved with turning oil into a useable energy source than you are putting into your figures. Once a wind farm is built there is almost no transport costs and almost no matenence or refinement costs. It is turned directly into energy and sent to the grid.
Now you are correct that lifestyles will have to change, Big deal, Lifestyles have been changing since the beginning of time. So we have to drive around in hybrids or electrical cars. No more high horespower street rods. That is hardly gloom and doom, It is just another way to live. My car does not make me Happy. If I had an electric car and so did everyone else, my quality of life would be just fine.
And please don’t argue that electric cars are not good enough to work for the entire population. Sure they are crappy right now, there has not been that much attention spent on developing them. Once this crisis of yours hits, All the major manufacturers will be coming out with a new better electric car every month, just like they are doing with gas cars now.
Secondly With electric cars having admittadly less HP than a gas engine, Likely less accidents will occur and therefore less healthcare costs to the entire country, as well as less automobile deaths. Also an electric engine is far lighter than an internal combustion engine, this also means lighter cars and less severe accidents. There are so many factors that are involved when a system such as this changes. Nobody can know the ultimate impact it will have but I have a feeling that we as humans will overcome anything that is presented us as a challenge. Might things get bumpy, sure they will, change is always a tough pill to swallow. But we will get through it.
