Photoshop Elements :: Way To Have PSE12 Default To Save As JPEG

I am changing from PSE8 to PSE12 and realized upon trying 12 today that PSE12 automatically saves my edited pictures in PSD format where PSE8 saved them in JPEG.  I don't use the organizer for catalogs, instead opening up folders where I've saved my pictures (e.g. Christmas 2013)and editing the photos I like in PSE8 and then saving them back in that same folder.  It may not be the 'right' way, but it works for me.  The picture I tried using PSE12 on, saved in the PSD format which isn't viewable in those folders (windows picture viewer is the default).  I truly only use PSE for improving pics I like and want to share/email, use as my desktip background, post to Facebook, and print for myself or gifts via uploading to a photo printing service (Mpix, Walmart, etc.)  Is there a way to have PSE12 default to saving as JPEG or should I be saving everything as PSD?  I get that PSD only works with PS and takes more space, but doesn't cause loss of quality of the pictures the way JPEG does ~ I'm just not sure it's important for the way I use PSE. \
