Like every small business, school, and personal home we should use solar power to power our school. It’s simply the cleanest, and most renewable energy source we have. The sun is expected to last another 5 trillion years. And once it dies we will too. If we invested only 50-200 billion dollars in research for solar panels we would lower the cost to that of coal. Which is a tiny fraction of the 10 Trillion dollars we spent in iraq. There is enough harness able energy from the sun to power the earth 4 times.
