Are these good enviormental savvy ideas?

It recently dawned on me that we don't have foever to change the world and our ways. Water, electricity and oil are not limitless and i read a book called water wars which highlighted the starlting future thats coming closer to reality eevry day if we don't change our wasting habits. Some really good ideas i was able to conqure up for helping the enviorment off the top of my head are to only use 90% of lights in schools, u know those florescnet bulbs? There plenty bright and would work just as well with one off or one bulb unused and that light thats off could rotate to extend the bulbs lifespan. Also using auto sinks, paper towl dispensers and flushing toliets EVRYWHERE would REALLY help, in one or two places only helps so much but applying them everywhere would make a huge difference, also using low water flow faucets in homes and showers would help a TON!!!! I c water saving faucets in biusness buildings but NEVER in homes. Theres more hoems on earth than biusness buildings. Also a few more ideas are auto shut off lights in homes, etc... Also using a lot less highway lights would help because cars have lights and how much lights do we really need on highways? The last energy saving idea i had was to gradually reduce the sales of the old types of lightbulbs that arent the enerygy efficent ones, and to price the energy effeicent onces cheaper, if we did that i dare someone to try and tell me how its a bad idea. The energy efficent bulbs nowadaysa re as bright as the old oens and even dim. Thanks and plz no hurtful or comments that are derrogatory in nature.
