Are some governments taking 'peak oil' seriously?

(PhysOrg.com) -- One of the arguments that some bring up in defense of alternative energy is that of "peak oil." The idea behind peak oil is that, as a fossil fuel in limited supply, eventually we will reach a point where oil production hits its maximum capability -- and then begins to decline. Because there aren't endless supplies of oil, and because it is a finite resource, the idea is that we will reach a tipping point at which it becomes impossible to continue increasing oil production. Some even contend that we're already there.
