Yeah, it is definitely not a bad idea for heating fuel, feed chemical, racing fuel, jet fuel, etc... Just replacing the natural gas produced methanol would be nice. However, wind energy has high availability in the winter and batteries would make up for blizzards and shortfalls. Canada is having a lot of good results from wind energy. In addition, they make a ton of energy from hydroelectricity.

Every country is different, E-methanol may be a solution for a few places. However it is not something I would personally invest in.
