What is the answer to making the internet sustainable??   good thing is that because it runs on electricity, we can use the suns energy by use of solar energy collectors…as we get better and better technology we can harvest all that nature has to offer.   For now, consider the equipment you purchase and make sure to send all old electronics and batteries to an e-waste collection.    you could also host your internet locally, even at your own place and if you had a solar array, wallah!
