The world needs a new source of energy, an unspillable source.

In the interest of conserving electricity & kinetic energy, how can I decrease the MPG of my Toyota Prius?

I’ve taken a new interest in the environment and conserving energy. I feel that if I lower my miles per gallon in my Prius, I will be using less kinetic energy to power it. Less kinetic energy used will mean less kinetic energy pollution that results from hybrid technology. Can I get a kit to do this, or do I need to take it to the dealership?
