Generally speaking, we're finally living in the world of peak oil. Or call it plateaued oil if you like, since we seem to have hit a rough plateau in oil production that's likely to continue for quite a while. This is the world of the vicious circle: when the economy gets better, demand for oil goes up and oil prices spike. This causes the economy to tank, which sends demand for oil down. Rinse and repeat. Add to that the effect of external events on oil prices (the Arab Spring, pipeline breakdowns, embargoes on Iran, etc. etc.) and world economic growth is likely to remain both sluggish and unstable for the foreseeable future, held hostage to OPEC oil production until we get serious about alternative energy. And since, in this brave new world, the price of oil gyrates frequently and erratically, it's hard to get people serious about this. If oil were, say, permanently above $200 per barrel or so, we'd be building wind farms and installing PV solar at breakneck speed. But whenever the price of Brent falls below $90 or so, everyone gets nervous and wonders if wind farms and solar arrays are really such a good investment after all.
The uncomfortable truth is that we'd probably all be better off if the federal government simply taxed oil variably at a rate that set the all-in price at $200 no matter what the market price was. That would be high enough to get everyone serious about more reliable energy sources and stable enough that investors would be falling all over themselves to fund alternative energy projects. And since it's oil price spikes that hurt the economy more than high oil prices per se, this probably wouldn't even have a major impact on growth.Read it at Mother Jones
