Why is Obama willing to ruin the worldwide economy to save 3% on fossil fuel?

Obama said he "WANTS GAS PRICES TO BE HIGH SO THAT WE GO GREEN." He does not allow oil drilling. With high gas prices the whole economy crashes. It also causes inflation. If we drilled oil the gas prices would drop, it would create 1000s of high paying jobs, put trillions into the economy and make trillions in tax revenue. So why is Obama still not allowing oil drilling?
