One SJCOG performance measure tracks average energy usage per household. The lack of available sources tracking annual energy usage makes monitoring this indicator over time difficult. However, SJCOG’s Envision Tomorrow modeling tool (which takes existing and previous place conditions and analyzes community growth patterns) measures energy usage per household to better understand environmental impact, household budget, and building efficiency of San Joaquin County households. This graph shows annual residential energy use, per 1,000 BTU per unit, in 2015. According to the graph, the most efficient housing types and energy categories are multi-family and single-family small units.
Total Residential Electricity Consumption
Naturally, total residential energy consumption has increased throughout the years. However, some years saw unchanging or decreasing energy from the previous year despite residential growth, indicating less energy usage per person or greater energy efficiency. In 2019, San Joaquin County residents collectively consumed nearly 1.9 million kilowatts (1,900 gigawatts) of electricity.
