Key Units of Measurement:
- Joules: The basic scientific unit of energy.
- Kilowatt-hours (kWh): Common for measuring electricity consumption.
- British Thermal Units (BTUs): Measures the heat content of fuels.
- Barrels of Oil Equivalent (BOE), Tons of Oil Equivalent (TOE): For comparing different energy sources.
Why Is Energy Consumption Important?
- Economic Indicator: A high correlation exists between energy consumption and economic growth.
- Environmental Impact: A large portion of global greenhouse gas emissions stem from energy production. Tracking consumption informs environmental policies.
- Resource Planning: Governments and organizations base energy infrastructure and investment decisions on energy consumption trends.
