It's easy to take electric power for granted, unless the power goes out or it's time to pay the bills. Lately we've all been more aware of our power use because of California utility company financial problems and shortages. I always watch the power lines on my way to school because they are such a prominent perch for hawks and osprey. Where does our local power come from? Why are there so many different types of power poles with different numbers of wires? How can birds perch on power lines without getting electrocuted? Could we do the same?
