Sure. That's a very good point and something the committee needs to think about.
The way to think about the supply of natural gas is in a North American context as opposed to a Canadian context. Indeed, in order to ensure the natural gas we're going to need in North America over the next several decades, we're probably going to have somewhere up to as much as 20% of our supply coming in through liquefied natural gas, in all likelihood. There's lots of gas in North America, but it's getting more expensive to get at and it's taking a long time to get the projects under way, as you're well aware. So it's absolutely critical that we do find ways to use it as efficiently as possible, right across the board.
We should be using it with 90% efficiency furnaces in our homes. We should be starting to invest in alternative ways of heating our homes, such as ground-source heat pumps. We should be making sure, where we have opportunities, for example, through direct burn, to use it that way as opposed to using it through central electricity generation, where you're getting maybe somewhere between 40% and 50%, or 60% at most, whereas in direct burn you can get over 90%, or in a combined heat and power application you can get about 90%. We should be using natural gas at those efficiencies, not the traditional ones.
