You could, but it might be more difficult. You could also light a few candles and try to draw energy from the fire, or you could sit by an electical plug and try to siphon off some electical energy. The earth is plentiful, which is why it is suggested for beginers, faster results occur the more energy you can siphon off. Earth is easier for beginers because they have limited ability to manipulate energy, which is why you would be doing exersises in the first place.
