It is not fully correct to say that quarks and electrons are made of energy, as you say in conclusion to your post. Quarks and electrons are just quarks and electrons. There is no reason to say there are made of anything.

Finally, I only want to add that in fact, protons and neutrons are actually dynamical objects that can be seen differently as made of three quarks. But this probably go way much further than the aim of your very nice post ^^
