Just be careful if you practice playing electric guitar ‘acoustically’. The danger is you develop sloppy fretting and don’t realise because your guitar is not amplified.
When you do eventually ‘plug in’ you’ll discover all the buzzy, muted notes that you were previously unaware of.
If you can’t afford an amp then use headphones along with one of the little headphone amps that plug into your guitar.
Edit: have a read at this discussion over here.
