At $130/kg, there's enough for 80 years at current consumption (about 10 years if we use it for all our electricity), but if we're willing to use ore with a tenth as much uranium, there's 300 times as much. Also, there's ways of using uranium 238, which is about 140 times as abundant. It's still a temporary patch, in the sense that we can't just keep using it until the sun goes out, but it will last long enough for fusion power to become economically feasible.
