I think the focus on affordability is an appropriate one. It's a concern for constituents in your riding, Mr. Zimmer, and in constituencies right across the country. It's something that we focus on all the time.
As I noted, we offer the most affordable energy option to Canadians. Right now, we're meeting about 35% of energy needs, and that percentage is growing. We expect it to grow to 40% in the next 20 years. The reason it's growing is that customers, residential or commercial, are looking for an affordable energy option, and we offer that.
That said, Canadians and Canadian governments are committed to emission reduction targets. The question then is what the most cost-effective emission reduction option is that you can pursue. RNG, we think, is one of the most cost-effective emission reduction options. There's a lot of it across the country because of a very robust agricultural industry and a robust forestry sector. We're working on a variety of projects to try to bring that supply to market in the most cost-effective way possible.
In our view, it's probably the single most affordable renewable fuel option, significantly more affordable in many applications than conventional electricity, much less renewable electricity. However, it is still more expensive than natural gas.
The way to support it and the way to drive those costs down is to partner with industry where possible on new technology developments. I mentioned our natural gas innovation fund. We're investing in roughly a half-dozen RNG companies across Canada that are working on new technologies to make RNG in markets across the country, and looking to build on those kinds of investments and to expand them across the country.
