Electricity

Electricity supply is in the forefront of public concern. This is because electricity end use is so darn useful. Effective Transition Engineering in the electricity area requires knowledge, consideration and contextualization of the whole energy system:

  • Natural Resource Extraction, Civil Engineering Infrastructure
  • Emissions, Pollution, Biodiversity, Water Use, Land Use, Mineral Use
  • Mechanical and Electrical Power Engineering of Energy Conversion Processes and Technology, EROI
  • Power Engineering, Transmission Lines, Dynamics and Controls
  • Markets, Costs, Policy, Standards, Social Justice, Economic Benefit
  • Mechanical and Electrical Engineering End Use Devices, Conversions, Energy Services
  • Quality of Life, Risks, Security, Safety, Sustainability

The one common element that has come out of all of the Transition Engineering work in electricity to date is one critically important and disturbing idea: 

Western societies use too much electricity and demand must decline in order to transition to low-carbon renewable energy systems.

 Critical Peak Demand

Christchurch, New Zealand - Critical Peak Demand

Details  The critical peak demand in Christchurch is in the winter evenings and mornings. The winter air pollution greatly exceeds health standards due to wood burning in about 10% of households. The peak loads are predominantly residential.  More than 40% of housing stock has no insulation. Aside from wood, household end-uses are almost exclusively electric. Electricity prices have been rising substantially. There are several scenarios that could improve security and help to manage costs, but there are also some surprising shift projects that have come out of considering this wicked problem.Tags    Energy Transition
