Study Notes

Energy Economics Study Notes

Energy is crucial for economic activity, requiring specialized study.
Strategic importance: Reliable energy is vital for quality of life.
Economic relevance: Energy is a major economic sector with substantial investments.
Exhaustibility: Many energy sources, like fossil fuels, are finite.
Equity and access: Ensuring fair resource distribution is a challenge.
Environmental impact: Energy use affects ecosystems and climate.
Rapid technological changes: Innovation influences energy extraction, storage, and generation.
Geopolitical influence: Control over energy resources impacts international relations.

Energy Reserves

P90 represents 90% confidence in reserve estimates for exhaustible resources (fossil fuels).
P50 represents 50% confidence in estimates, a less certain measure of reserves.

McKelvey Box

A model to classify fossil fuels based on economic and geological factors.
Proven Reserves: High certainty & economically extractable with current technologies.
Probable Reserves: Moderate certainty, nearly economically feasible.
Inferred Resources: Less certain, technologically challenging to extract.
Speculative Resources: Low certainty, high extraction costs, and uncertain feasibility.

Reserves vs. Resources

Resources: The total amount of a source in nature (known & unknown).
Reserves: The economically feasible and known portion of resources.

Energy Source Classification

Renewable: Naturally replenished (e.g., solar, wind, hydro, geothermal).
Non-renewable (exhaustible): Finite sources (e.g., coal, oil, natural gas).

Energy Intensity and CO2 Emissions

Energy intensity measures energy consumption per unit of output (e.g., GDP).
Higher intensity generally correlates with higher CO2 emissions if fossil fuels are primary energy source.
Lower intensity signifies greater energy efficiency, reducing CO2 emissions.

R/P Ratio

Reserves to production: A ratio estimating how long current reserves will last at the current production rate.
R/P = Reserves / Annual Production.
Useful for assessing resource longevity, considering future discoveries, demand shifts, and technological advancements.

Perfect Competition Market

Many small buyers and sellers.
Homogenous products (no differentiation).
Perfect information (complete knowledge).
No barriers to entry or exit.
No single firm controls price; firms are price takers.
Price equals marginal cost for optimal resource allocation.
Price equals marginal production cost; firms produce till this point.

Market Failures

Imperfect competition: Monopolies, oligopolies, monopolistic competition—prices are higher, outputs lower.
Externalities: Costs or benefits impacting third parties not directly involved (e.g., pollution).
Public Goods: Non-rivalrous and non-excludable goods (e.g., national defense).
Scale Economies: Large firms have lower average costs compared to smaller ones, leading to potential monopolies.
Resource exhaustibility: Markets often undervalue finite resources, causing overexploitation of non-renewables.

Monopoly

A market structure with single supplier and unique products/services.
Firms decide quantity to maximize profits where marginal revenue equals marginal cost.
Price is higher than marginal cost because demand curve is downward sloping.

Natural Monopoly

An industry where one firm can serve the market at lower cost than multiple firms.
High start-up costs and economies of scale are key characteristics.

Energy Balance

A framework for tracking energy production, transformation, and consumption.
Tracks primary energy sources to final energy uses.
