Elias's awesome analysis of Sustainability!

1. Sustainable - able to be sustained; able to be sustained for an indefinite period without damaging the environment, or without depleting a resource; renewable

2. The amount of energy and resources needed to keep the community going.

3. As the demand for energy increases with the population and technology increases it becomes harder to maintain sustainable living.

4. Become more energy efficient by not using fossil fuels but instead using renewable resources and alternate energy sources such as wind, solar and hydro energy.
