Inequality and Energy: How Extremes of Wealth and Poverty in High Income Countries Affect CO2 Emissions and Access to Energy challenges energy consumption researchers in developed countries to reorient their research frameworks to include the effects of economic inequality within the scope of their investigations, and calls for a new set of paradigms for energy consumption research. The book explores concrete examples of energy deprivation due to inequality, and provides conceptual tools to explore this in relation to other issues regarding energy consumption. It thereby urges that energy consumption approaches be updated for a world of increasing inequality.

Extreme economic inequality has increased within developed countries over the past three decades. The effects of inequality are now seen increasingly in health, housing affordability, crime and social cohesion. There are signs it may even threaten democracy. Researchers are also exploring its effects on energy consumption. One of their key findings is that less privileged groups have lost consistent access to basic energy services like warm homes and affordable transport, leading to huge disparities of climate damaging emissions between rich and poor.

This is a definitive guide to the rebound effect in home heating – the increase in energy service use after a technological intervention aimed at reducing consumption. It sets out what the effect is, how it plays out in the home heating sector, what this implies for energy saving initiatives in this sector, and how it relates to rebound effects in other sectors. The book outlines how the concept of the rebound effect has been developed and the scope of research on it, both generally and particularly in the home heating sector. Within the context of energy and CO2 emissions policy, it summarises the empirical evidence, exploring its causes and the attempts that are being made to mitigate it. Various definitions of the rebound effect are considered, in particular the idea of the effect as an energy-efficiency ‘elasticity’. The book shows how this definition can be rigorously applied to thermal retrofits, and to national consumption data, to give logically consistent rebound effect results that can be coherently compared with those of other sectors, and allow policy makers to have more confidence in the predictions about potential energy savings.

Germany is seen as a leader in thermal retrofit policy and practice, but how effective is its approach? A Critical Appraisal of Germany''s Thermal Retrofit Policy examines this policy in context and assesses its effectiveness. It finds that technical constraints and the costs of retrofitting reduce the rate of progress, while planning underestimates the influence of user behavior in the form of rebound and prebound effects. A key finding is that savings can be maximized within a policy that understands the actual behavior and motivation of households, the area where most energy savings are already taking place.

The book suggests a new policy paradigm that would encourage a better balance of partial and comprehensive retrofits, utilizing household behavior changes based on a better understanding of fuel saving motivation and fuel price elasticity. In this approach, the thermal building regulations would be made more flexible so that policymakers would:

- Promote partial, transitional and cost-optimal retrofits, which are more certain to pay back through fuel savings if they are appropriate to building typology and homeowner budgets.

- Promote comprehensive retrofits for reasons other than economic gain, focusing instead on the comfort and environmental benefits of energy-efficient homes.

-Invest more heavily in educating households to heat economically, learning from the prebound effect so as to maximize the utility of the homes they currently occupy, and base payback time calculations on actual consumption.

The results and findings of this book would be of interest to policymakers, researchers and graduate students alike.
