Yes, it is time to take action. When I build my treehouse it will be powered by the sun. (Solar panels). People and their governments know that solar panels and wind turbines work, and it beats me why they are not trying to perfect them and make them available to everyone in every community. Yes, they are costly, but so is oil, coal, and nuclear generated electricity, especially now in this global recession. But once installed, you may never need to receive a monthly bill from the hydro company. They are also clean and reusable.
