Internationally accepted policy is to have a balanced and stable price. If the price for oil is too high, huge wealth transfers to the oil producing countries where as the oil consuming countries can't afford to produce or ship products. This sparks a recession which will inevitably lead to reduced demand for everything, including petroleum products.
Alternative energy sources in consuming countries introduce a stabilizing factor that benefits the entire energy sector. Iran is an interesting case. As an oil producer, their nuclear bid is causing instability and is in line with other aggressive behavior that should be a major cause for concern. The Iranian system of Valeyat -E-Faqhee or supreme religious rule is a regressive and confrontational system. The fact that they own a significant portion of the world's proven energy reserves is very disconcerting, to say the least.
Interesting analysis. If Iran goes nuclear, they wouldn't need to consume their own oil product and would have more to sell, but they are a smallish market themselves. If India goes more nuclear, they wouldn't need so much oil product. Same for China, Japan, EU, and America, the major and coming major consumers.
