But shouldn't we be on the cusp of using less and less oil as the years progress ?
That would be nice. I'm just not so sure. Yes, we have efficiency gains on the horizon. But economic growth in the past has always outstripped past efficiency gains.
Right now we are about to have an explosion of electric cars ( volts , leafs , fusions and others) solar and wind continue to drop in price and will be used more and more. Gas is going to continue to rise , its up around 32cents here in jersey since this time last year and regular is almost at $3 again . I don't doubt that this time next year it will be close to $3.25 for regular and by the middle of the decade i can see it pushing close to $5 for premium so the incentive is there for new cars
Yes. But these new cars take time to develop. And cars aren't the only thing that use oil.
The real concern, however, is hoarding. If no nation hoards oil, we will be looking at a gradual, if painful, increase in oil prices as time progresses. But once one nation decides that it can no longer afford to export oil, as it will itself soon be too low on this resource to even support its own economy, there will be a sudden drop in the global oil supply. If enough nations do this, we could be looking at a supply shock in oil of crisis proportions.
So it makes sense to be as aggressive as we possibly can be in reducing our oil usage. The less oil usage we have when such hoarding inevitably occurs, the less painful it will be.
My question is this. If we were able to snap our fingers and make every car in america a full electric vehicial what would that do for global warming ? Will we see any effect at all ?
Basically, it'd slow the increase in temperature. The first thing you have to recognize, however, is that changing to electric would mean that coal power would now be supplying these cars. So you've, in part, just traded one fossil fuel for another. However, electric cars still, on average, result in much less CO2 emissions, even when powered by coal plants (especially if they're charged almost exclusively at night). So there would be an improvement, but it wouldn't be terribly dramatic.
Fighting global warming really requires broad initiatives tackling every form of greenhouse gas emissions, from transportation to power generation to factory farms.
