In our own simple ways, we can help address and help the issue on energy crisis. We can close the lights when not necessary; unplug switches when unused, and simply using the sunlight as a light source if possible. Turning of the faucet while brushing or when it is not necessary can also help. With all this done by people, effects can be exponential for the better. Just imagine more people doing the means to help the issue in energy crisis; the minority would obviously follow to avoid deviation! Then in due time, the complete use of bio fuels, fluorescent light bulbs, or even solar panels can change the world!
