Sustainable Energy Explained

I came across this video which is somewhat related to my last post but merits its own entry. While none of the information is very new, it is a great synopsis of what sustainable energy is, the different alternative energy options we have available to us now, how much they are being used, and what our future possibilities are. The video also gives an overview of what we are doing to our planet with our current carbon and polluting emissions, and what the consequences are.
