How enviromentally friendly is using methane compared to other hydrocarbon fuels if you make it yourself?

I’ve been reading about making methane as a source of renewable energy but it seems to produce a fair amout of CO2 as well as other pollutants, is it really an enviromentaly friendly means of creating sustainable energy?

Which is going to grow more? Aerospace or Energy?

I’m trying to figure out what to major in, I know for sure it will most likely be mechanical engineering. However, ME is pretty broad, and most schools offer specializations in automotive, aerospace, energy/environmental, etc. fields.

So in terms of engineering, what branch of ME is projected to grow the most over the next few decades? The aerospace industry is rapidly commercializing, as demonstrated by SpaceX, but of course, sustainable energy is one of the biggest economical and environmental issues we face today.

What is a better option? Energy or aerospace?

Thanks for any input or explanations.
