Which Engineering degree/subject to study?

[Caveman_Love]

Hello
I have been thinking for a while to go to university/collage as I have been saving money for some time now
and I would like to study aboard in Canada . I am interested in some fields of the technology industry ,I would like to work and help advance the sector of propulsion energy technology of space and maybe civil , making the solar and other renewables more energy efficient so that we could have a more healthy living,making transporting better and
in general invent something that will help advance us in a better way.I know some of it sounds as a cliche ..
what Engineering degree should I peruse in order to get into the above fields of subject

A got a few problems one of them is that I am 23 years old and by that age some people already have a degree isn't it late? the other factors is the fact that I will need to start some subjects from scratch because in high school they didn't allowed people with lacking math to participate in Physics class and other science based class's ..

I will really appreciate those who will help me

p.s
I am new to this forum

For energy sectors it sounds like a base in electrical engineering is your first step.
