Study Notes
Energy Basics
- Energy is used to perform various activities such as walking, bicycling, cooking, and manufacturing products.
- Different forms of energy include heat, kinetic energy, light, and electrical energy.
- Energy is measured in joules (J), where 1 joule is equal to 1 newton-meter (N*m).
Renewable Energy Sources
- Renewable energy sources are replenishable and can be generated again.
- Examples of renewable energy sources include wind power, solar power, hydropower, and geothermal power.
- Wind power involves the installation of offshore and onshore turbines to convert wind power into electricity.
- Solar energy is the conversion of solar power into electricity using photovoltaic (PV) panels.
Energy Demand and Econometrics
- Energy demand is affected by income, prices, and other explanatory variables.
- A commonly used model to estimate energy demand is: logEt = α + b * logYt + c * logPt + εt.
- Energy demand can also be affected by lagged dependent variables, implying that energy demand in a period is directly affected by the demand in the previous period.
Fossil Fuel Importance and Energy Consumption
- Fossil fuels have been the primary source of energy for centuries.
- Energy consumption per capita has increased significantly over time, with average energy consumption in the early Roman Empire being around 18 GJ/capita and in modern times being around 153 GJ/capita in England and Wales.
- Fossil fuel reserves are concentrated in a few countries, making it challenging to ensure an undisturbed supply of the resource.
Measuring Energy
- Energy sources use different units of measurement, including barrels (bbl) for oil, cubic feet (ft3) for natural gas, and gallons (gal) for gasoline.
- Units of energy output include calories (cal), joules (J), and watt-hours (wh).
Energy Market and Challenges
- The energy sector is a significant contributor to greenhouse gas emissions and climate change.
- Energy markets are characterized by monopolistic and oligopolistic structures, which can create problems of efficiency and energy security.
- Accidents in the energy sector can have environmental disasters, such as the Deepwater Horizon oil spill in 2010.
