The hot plates on an electric stove change electrical energy into heat and a small amount of light energy.

This is because electric stoves utilize electricity (hence the name), and as they convert the electricity into the heat that is used for cooking, they also light up slightly to indicate that they are on (a safety measure). 

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
