Dan Crawford reports for the Republic, "Vancouver's opinionated newspaper," from a talk by Dave Hughes of Natural Resources Canada that there is only
eight years of natural gas left in Canada:
Consumption trends and patterns were also explored. In every case, the phenomenal growth rates in our economy show a complete disconnect with the reality of the resources currently supporting them. Canada, for example, has 8.1 years left in natural gas reserves.
This isn't entirely correct.
According to the latest
annual review (pdf), as of January, 2004, there were 68 Trillion cubic feet (Tcf) of
proven natural gas reserves, 171 Tcf of
discovered resources, and 366 Tcf of
undiscovered resources (check out the
2000 review for detailed definitions of these terms). In 2004, 5.9 Tcf were extracted.
The prediction of 8.1 years is quite obviously based on
proven reserves.
If you include
discovered reserves — the ones that are drilled and known with certaintly, but are too far from existing pipelines to economically extract currently — that number more than triples. Once you add to that the
undiscovered reserves — known to contain gas, but not yet drilled — the number grows much larger.
So we have more than 8 years before we're forced to replace our furnaces and water heaters with
something else, although it's easy to point out
compelling reasons to switch sooner.
