Let me tell about “spend so much energy.” The resource of energy is fuel of fossil. Drive your car to go to somewhere, turn on your computer overnight. The result or the effects are air pollution, ozone depleting, ice melting, etc. maybe the resource of energy is going to rare in 50 years.
Do not worry about it; there are so many ways to save our earth. I found a website, http://www.savewithces.com/365in2008.html. In that website, you can find how to save energy. There are so many ways, 365 ways to save energy. Energy is very limit. Saving energy not important for you but for your next generation. How about the result if you save energy? Imagine it, all people use public transportation, what do you think? There are not traffic jams, right? Air condition is clean, what else’s? The important effect is you save your money. Save energy save our planet and save the other, just not human, but living things.
