This document discusses sustainability, sustainable development, and how to achieve sustainability. It defines sustainability as meeting present needs without compromising future generations' ability to meet their own needs. Sustainable development aims to maintain socioeconomic systems indefinitely while fulfilling human needs and preserving the environment. The current socioeconomic system prioritizes exponential growth and is unsustainable due to finite resources. To achieve sustainability, the document proposes replacing the current system with a "Technocracy" where experts manage production to maximize living standards for as long as possible using energy credits instead of money.
