I think, obviously, if we consider decarbonization a key rationale and driver, most of our carbon emissions in the electricity sector today can be found in Alberta, Saskatchewan, New Brunswick, Nova Scotia, and Ontario. Interties that help to reduce those carbon emissions are going to be strategically important going forward. You're absolutely right that there is a range of pathways that we'll have to follow in terms of decarbonization.
When I'm talking about looking longer term, I'm thinking of it more in terms of specifically what the demand for electricity is going to be longer term. There have been decarbonization analyses done for the United Nations looking at Canada that said that electricity has to move from less than a quarter of our total energy, like oil and everything else today, to close to 50% by the time we get to 2050, a doubling. That's a lot of new electricity coming online.
We need to consider what resource availability is in different jurisdictions. There are some jurisdictions that have the potential to develop more than others. We need to think about that in determining where it strategically makes sense to go forward. We also have to look at costs, obviously, as well.
There is going to be a mix. Interties are not the sole solution by any stretch of the imagination. It's going to be a diverse strategy that will be required to be followed and go forward. I can't offer you an answer today that says it's going to be precisely these two interties and it's going to have to be this size.
I'm suggesting that we do need to be very thoughtful about it in that regard. The only thing I would say, I guess, is that any projection of renewable energy development that has occurred over the last 20 years has undershot significantly. Renewables have been developing much, much faster. When we're looking forward and going ahead, we just need to keep that in mind, that the trends that we're seeing both technologically and economically that are driving renewables forward are likely to accelerate the introduction of these technologies into the grid. We want to make sure that, when we're making infrastructure investments, we're sensitive to that.
