We need to switch to 100% renewable resources by 2020. Together we can make this happen.
Documentary videos include Wilson Natural Home (25 minutes), The Solar Village (45 minutes), and Hope for a Change: Renewable Energy (60 minutes, featuring Dr. David Suzuki, Dr. Hermann Scheer, and Chris Turner).
Solar based ecological restoration and biomimicry Published: February 18, 2011 How can architects build a new world of sustainable beauty? By learning from nature. At TEDSalon in London, Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.
Michael Pawlyn explains the genius in nature that we could use to achieve factor 100 savings in resources. Three big changes we need:
radical resource efficiency
from linear to closed loop systems
solar power driven processes
Ideas from nature can allow us to reduce resource requirements. The Eden Project created a massive greenhouse with alternative materials to glass that made the entire structure weigh less than the air inside.
We could transform the waste in cities to a closed loop resource recycling process. Cycles of food, waste and energy can be combined to transform linear systems into closed loop systems. Sahara greenhouse projects are find ways to de-salinate sea water, including the damaging waste from desalination plants, in order to create resources and reverse desertification.
