• Based on the components of an average household budget expenditure (figure A1) and the discussed data sources, a spreadsheet modeling tool is provided to visualize how energy costs can affect household budgets under different scenarios
• Scenarios to be translated into differential energy costs across geographies
• Parameters to change in model: growth rates for income, electricity and fuel costs
• Outcomes: Share of energy expenditure for average household budgets over time and across space
