Summary of Household Energy Supply and Use in Yemen: Volume II, Annexes

Core Content

This document is part of the Household Energy Survey (HES) conducted in Yemen as part of the ESMAP (Energy Sector Management Assistance Programme), a joint initiative by the UNDP and the World Bank. It focuses on the energy supply and use patterns in Yemen, particularly at the household level, and includes detailed annexes that cover various aspects of energy consumption, including kerosene, diesel, LPG, gasoline, fuel oil, electricity, and biomass.

The report aims to provide comprehensive data and analysis to support energy policy and development planning in Yemen. It includes both survey methodologies and economic and social analyses of energy usage, with a special emphasis on the impact of subsidies and pricing on different sectors of the economy and on household behavior.

Main Purpose

• To understand household energy supply and use in Yemen.
• To provide data and insights for energy policy development and poverty reduction.
• To analyze the impact of energy subsidies and pricing on households and other sectors.

Key Areas of Focus

1. Survey Design and Implementation

   • A stratified two-stage random sampling technique was used.
   • The survey included both urban and rural areas, excluding Al-Jawf, Marib, and Al-Marah due to high costs.
   • Village and neighborhood heads were involved in data collection.
   • Training of supervisors and enumerators was conducted to ensure quality data collection.

2. Energy Consumption Patterns

   • Detailed data on the usage of kerosene, diesel, LPG, gasoline, fuel oil, and electricity.
   • Income decile analysis was used to assess the distribution of energy use and expenditure across different socio-economic groups.

3. Subsidy Analysis

   • Diesel and LPG subsidies were analyzed for their direct and indirect effects on household budgets and other sectors like water, food, and qat.
   • The impact of removing subsidies and increasing prices to economic levels was evaluated.

4. Price Analysis

   • Retail prices of different fuels were examined.
   • The relationship between price changes and economic indicators (e.g., GDP, inflation) was analyzed.

5. Biomass and Fuelwood Use

   • Fuelwood and charcoal consumption was analyzed, including the labor input and collection time.
   • Income distribution and geographical disparities in biomass use were highlighted.

6. Data Reconciliation

   • The report discusses the reconciliation of survey data with income and expenditure data.
   • It includes comparisons with previous surveys to ensure data consistency and accuracy.

Main Findings and Insights

• Survey Coverage: The survey included 3,625 households, with 1,585 urban and 2,040 rural households.
• Sampling Design: The sample was stratified by governorates and income deciles.
• Energy Use by Income Decile:
  • There is a significant variation in energy use and expenditure across different income deciles.
  • Lower-income households spend a larger proportion of their income on energy.
• Subsidy Impact:
  • Subsidies on diesel and LPG have negative economic effects.
  • Eliminating subsidies leads to increased prices and reduced consumption, especially among lower-income households.
  • There is a link between energy prices and other goods, such as water and food.
• Biomass Usage:
  • Fuelwood and charcoal are the primary biomass fuels used in rural areas.
  • Collection distance and household size influence the labor input required for fuel collection.
  • Lower-income households are more likely to use biomass due to cost constraints.

Conclusion

The report offers a comprehensive overview of household energy use in Yemen, emphasizing the economic and social implications of energy subsidies and pricing. It provides detailed data on consumption patterns, price structures, and the impact of energy policies on different income groups. The methodological rigor of the survey, including stratified sampling and data reconciliation, ensures the reliability of the findings. The insights from this report are crucial for energy policy formulation and poverty alleviation in Yemen.
