Engineering can play an important role in sustainable development by focusing on meeting human needs over wants and prioritizing projects that serve the most vulnerable populations. Engineers should consider how their work impacts sustainability, affordability, and accessibility. A socially sustainable product is manufactured sustainably and also improves people's lives. Engineers are not neutral and should strive to serve societal needs rather than just generate profits. They can help redefine commerce and an engineering culture focused on meeting needs sustainably through services rather than creating unnecessary products and infrastructure.
Consensus and interaction on a long term strategy for sustainable developmentSSA KPI
The document discusses the need for a long-term vision for sustainable development to address major challenges like climate change, resource depletion, and inequity. A long-term perspective is required because these problems will take consistent action over many years to solve. However, short-term solutions may counteract long-term goals if not guided by an overall strategic vision. Developing a widely accepted long-term sustainable development vision requires input from many stakeholders to find balanced solutions and avoid dead ends. Strategic decisions with long-lasting technological and social consequences need a vision that can adapt to changing conditions over time.
Competences in sustainability in engineering educationSSA KPI
The document discusses competencies in sustainability for engineering education. It defines competencies and lists taxonomies that classify competencies into categories like knowledge, skills, attitudes, and ethics. Engineering graduates are expected to have competencies like critical thinking, systemic thinking, and interdisciplinarity. Analysis of competency frameworks from different universities found that competencies are introduced at varying levels, from basic knowledge to complex problem solving and valuing sustainability challenges. The document also outlines the University of Polytechnic Catalonia's framework for its generic sustainability competency.
The document discusses concepts related to sustainability including carrying capacity, ecological footprint, and the IPAT equation. It provides data on historical and projected world population growth. Examples are given showing the ecological footprint of different countries and how it is calculated based on factors like energy use, agriculture, transportation, housing, goods and services. The human development index is also introduced as a broader measure than GDP for assessing well-being. Graphs illustrate the relationship between increasing HDI, ecological footprint, and the goal of transitioning to sustainable development.
From Huygens odd sympathy to the energy Huygens' extraction from the sea wavesSSA KPI
Huygens observed that two pendulum clocks suspended near each other would synchronize their swings to be 180 degrees out of phase. He conducted experiments that showed the synchronization was caused by small movements transmitted through their common frame. While this discovery did not help solve the longitude problem as intended, it sparked further investigations into coupled oscillators and synchronization phenomena.
1) The document discusses whether dice rolls and other mechanical randomizers can truly produce random outcomes from a dynamics perspective.
2) It analyzes the equations of motion for different dice shapes and coin tossing, showing that outcomes are theoretically predictable if initial conditions can be reproduced precisely.
3) However, in reality small uncertainties in initial conditions mean mechanical randomizers can approximate random processes, even if they are deterministic based on their underlying dynamics.
This document discusses the concept of energy security costs. It defines energy security costs as externalities associated with short-term macroeconomic adjustments to changes in energy prices and long-term impacts of monopoly or monopsony power in energy markets. The document provides references on calculating health and environmental impacts of electricity generation and assessing costs and benefits of oil imports. It also outlines a proposed 4-hour course on basic concepts, examples, and a case study analyzing energy security costs for Ukraine based on impacts of increasing natural gas import prices.

Advanced energy technology for sustainable development. Part 5SSA KPI
All energy technologies involve risks that must be carefully evaluated and minimized to ensure sustainable development. No technology is perfectly safe, so ongoing analysis of benefits, risks and impacts is needed. Public understanding and acceptance of risks is also important.
Advanced energy technology for sustainable development. Part 4SSA KPI
The document discusses the impacts and benefits of energy technology research, using fusion research as a case study. It outlines four pathways through which energy research can impact economies and societies: 1) direct economic effects, 2) impacts on local communities, 3) impacts on industrial technology capabilities, and 4) long-term impacts on energy markets and technologies. It then analyzes the direct and indirect economic impacts of fusion research investments and the technical spin-offs that fusion research has produced. Finally, it evaluates the potential future role of fusion electricity in global energy markets under environmental constraints.
Advanced energy technology for sustainable development. Part 3SSA KPI
This document discusses using fusion energy for sustainable development through biomass conversion. It proposes a system where fusion energy is used to provide heat for gasifying biomass into synthetic fuels like methane and diesel. Experiments show biomass can be over 95% converted to hydrogen, carbon monoxide and methane gases using nickel catalysts at temperatures of 600-1000 degrees Celsius. A conceptual biomass reactor is presented that could process 6 million tons of biomass per year, consisting of 70% cellulose and 30% lignin, into synthetic fuels to serve as carbon-neutral transportation fuels. Fusion energy could provide the high heat needed for the gasification and synthesis processes.
Advanced energy technology for sustainable development. Part 2SSA KPI
The document summarizes fusion energy technology and its potential for sustainable development. Fusion occurs at extremely high temperatures and is the process that powers the Sun and stars.
