Clean Energy Choices: Resource Efficiency and Environmental Trade-Offs of Clean Energy Options

Project Overview

Today, fossil fuels are the main source of greenhouse gas emissions and air pollution, while also polluting land and water. Options to reduce this pollution include energy conservation, renewables, nuclear power and the mitigation of emissions from fossil fuel combustion. These options have various performance characteristics, including resource requirements and environmental implications. Many solutions work only in combination with others. To achieve a desirable outcome, we need to understand the characteristics and implications of different technologies not only at the level of the individual technology but the system level. This systems level includes:

  • the manufacturing and installation of energy conversion/efficiency equipment
  • the operations
  • the waste management
  • the role of a technology in the larger system, such as matching supply and demand

We have developed a global, multiregional life cycle assessment model to assess the production, operation and disposal of energy conversion devices in a scenario context. We are also developing assessment approaches more suited for energy efficiency options and consumer choices.

This project has already yielded a report for the International Resource Panel and Professor Hertwich has contributed to the assessment of the co-benefits and adverse side effects of climate change mitigation in energy systems of the IPCC.
