Global Decent Living Achievable with 1960s Energy Levels by 2050

Why It Matters

This research challenges assumptions about the necessary energy footprint for development, suggesting that technological advancement and conscious demand-side management can decouple human well-being from escalating energy use. Designers and engineers can leverage this insight to prioritize efficiency and sufficiency in their solutions, even for basic needs.

Key Finding

The study demonstrates that by 2050, the world can house, feed, and transport everyone to a good standard of living using the same amount of energy the world used in the 1960s, provided we embrace new technologies and reduce our overall consumption habits.

Key Findings

• Global final energy consumption in 2050 could be reduced to 1960s levels.
• Achieving this requires widespread adoption of advanced technologies and significant demand-side reductions in consumption.
• A 'decent' living standard, as defined in the model, is materially generous and achievable with reduced consumption.

Research Evidence

Aim: To estimate the minimum final energy consumption required to provide a decent material standard of living for the global population by 2050.

Method: Bottom-up modelling and scenario analysis.

Procedure: The researchers developed a model to calculate the energy requirements for various essential services (housing, transport, food, etc.) for a global population in 2050, aiming for a 'decent' but not excessive standard of living. They then analyzed scenarios involving technological advancements and demand-side changes.

Context: Global energy consumption and sustainable development.

Design Principle

Decouple human well-being from energy consumption through technological innovation and demand-side sufficiency.

How to Apply

When designing any product or system, consider its entire lifecycle energy demand and explore how to reduce it through material choice, operational efficiency, and end-of-life considerations. Advocate for and integrate sufficiency-oriented design strategies.

Limitations

The definition of 'decent living' can be subjective and may vary across cultures. The model relies on projections of technological development and societal adoption rates, which carry inherent uncertainties.

Student Guide (IB Design Technology)

Simple Explanation: We can live well using much less energy than we think, but we need smart technology and to be mindful of what we truly need.

Why This Matters: This research shows that it's possible to design for a better future without demanding ever-increasing amounts of energy, which is crucial for tackling climate change and resource depletion.

Critical Thinking: To what extent is the definition of 'decent living' culturally relative, and how might this impact the global energy demand projections?

IA-Ready Paragraph: This research by Millward-Hopkins et al. (2020) suggests that a decent global standard of living is achievable by 2050 with energy consumption levels akin to the 1960s, provided there is a significant rollout of advanced technologies and a shift towards demand-side sufficiency. This highlights the critical role of design in developing solutions that prioritize energy efficiency and reduced consumption, rather than simply scaling up existing high-energy-demand models.

Project Tips

• When researching materials, look for low embodied energy options.
• Consider the energy used by a product during its use phase and how to minimize it.
• Think about how your design encourages or discourages excessive consumption.

How to Use in IA

• Reference this study when discussing the energy footprint of your design or when justifying design choices that prioritize energy efficiency and reduced consumption.

Examiner Tips

• Demonstrate an understanding of energy consumption across the product lifecycle.
• Show how design decisions can influence user behaviour towards sufficiency.

Independent Variable: ["Technological advancement levels","Demand-side consumption patterns (sufficiency levels)"]

Dependent Variable: ["Global final energy consumption","Standard of living"]

Controlled Variables: ["Global population size","Year (2050)"]

Strengths

• Provides a quantitative model for a complex global challenge.
• Offers an optimistic yet grounded scenario for sustainable development.

Critical Questions

• What are the ethical implications of defining a 'decent' standard of living for the entire globe?
• How can designers and policymakers effectively encourage the adoption of sufficiency-oriented behaviours?

Extended Essay Application

• Investigate the energy footprint of a specific lifestyle choice or product category and propose design interventions to significantly reduce it, drawing parallels with the 'sufficiency' concept.
