Can two glyphs be used in succession?

At work and can't remember and trying to make a build:

Just wondered can you use

Glyph of lesser energy
Glyph of renewal
- then cast the renewal skill 15 less nrgy

Or does one glyph replace the other.

Thanks

No, the newest glyph will remove the older one.

same as stances, the glyphs replace eachother
