In this picture, in the right corner of the building, there is a red line. I would like to know what is it, what causes it, and how to prevent it. Any help is much appreciated.

Yeah, my cam is pretty old. So, no solution then?

It's a property of the lens. There is very little you can do about it on a powershot other than edit it out, most decent editors will have some form of CA minimisation.
It's also possible that it will be less apparent if you zoom in a bit... or maybe zoom out.. i guess it depends on the optical formula just as much as it depends on the direction, relative intensity and origin of the light.
Try looking up Chromatic Aberration, it might give you some insight.
But short answer is no. Fix it in post processing.

Thanks, I am going to do that. Any advice of why the blue sky shows as white?

Lack of dynamic range. Also a property of the cam.
Your sky is overexposed. Too much light on the sensor has caused the pixels to fill up (so to speak). Can't be fixed in post sadly.
Next time underexpose and see if you can recover / raise the shadows that will appear instead.

My cam is really shitty, isn't it? :(
Oh well.

Not particularly shitty in this respect, most cams would struggle i this situAtion, and most photographers would underexpose to save highlights and hope the shadows were recoverable.
If you're not already using them, check out Gimp & Faststone - they're free.

Actually, you're right - if it only shoots jpegs that's pretty bad when it comes to dealing with both the ca and dynamic range issues :(
