Electricity conservation

Recently, and in fact today, my whole house suddenly blacked out. Till now, we still have no idea what caused it to happen, but one thing we do know, that I realized today, is that electricity is something we never notice, but actually supports our lives a lot. We couldn't see, we were beginning to melt (I swear) and we just couldn't do anything but walk around, really. All of because the electricity got cut off.
We depend so much on this strange, almighty power that we use so much in our daily lives. Imagine what would happen if there were no more electricity. We wouldn't be able to do anything, especially at night. Not unless we found another way to light up our houses somehow.
This experience of mine helped me realize that we have to do something to help the Earth and everyone, everything on it. Energy can only be produced if we have the sources of energy we need. As yet, we are not entirely energy-efficient. We need to find ways to harness solar energy so that we can depend wholly on that for power supply, not keep burning up fossil fuels and other biomass.
Let's start today by first conserving energy. You don't ever get anything for greed, oh no. Never use more than you need. If you can, you could even try to use less than that. Just remember what I've told you. What do you think you should do?
