I learned that we use a lot of energy in 2010 now that we play video games go on facebook. We have microwaves ovens... We have a lot! Insilation Conserves insilition inside. It collects energy so its warmer inside. To be safe from energy you should stick things in outlets, have things plugged in when your not using them, dont put things on top of cords and have things near electrical wires. Trees give us less carbon then everything. Houses usemost carbon.
