Study Notes
Analyzing Energy Demand
- Objective is to meet a given exogenous energy demand by expanding the supply, while now analyzing and forecasting energy demand has become important.
Energy Demand
- It refers to any kind of energy used to satisfy individual energy needs such as heating, cooking, and producing.
- Energy products are used as fuel creating demand for energy.
Energy Demand vs. Energy Consumption
- Energy demand is a relationship between price (or income) and quantity of energy.
- Energy demand exists before a purchasing decision is made and is an ex-ante concept.
- Energy consumption takes place once the decision is made to purchase and consume and is an ex-post concept. -Energy consumption refers to the manifestation of satisfied demand and can be measured.
Economic Foundations of Energy Demand
- Estimating and analyzing the demand for energy is similar to other commodities.
- Characteristics of energy demand and issues in energy markets require particular attention when analyzing energy markets.
- Microeconomic foundation of energy demand is the same as it is for other commodities.
Reasons for Energy Demand
- Households consume energy to satisfy their needs by allocating income among competing needs aiming for satisfaction, while commercial users of energy demand as an input of production aiming to minimize the total cost of production.
- Because motivations differ, any energy demand analysis should separately consider consumer and producer energy demand.
Consumer Demand: Utility Maximization
- Microeconomic basis for consumer energy demand relies on consumers' utility maximization principles.
- Consumers know their preference sets and ordering of the preferences.
- Preference ordering can be represented by some utility function.
- Consumers are rational and will always choose a preferred bundle from alternatives.
- Indifference curves show various combinations of two goods that give consumers equal utility, with higher curves representing higher levels of satisfaction.
- Budget Constraint: A limitation on the amount of goods consumers can purchase given limited income and prices.
Optimal Demand
- To determine the optimal level of two goods, you must solve the following:
- Construct budget constraint.
- Calculate MRS (slope of Indifference curve).
- MRS = (Marginal utility of Good x) / (Marginal utility of Good y).
- Find slope of budget constraint
- Budget slope = (Px / Py)
- Equate the two slopes and solve
- Changes in price of energy affects the optimal demand for energy and other commodities.
- Energy Demand Curve is downward sloping due to increase in quantity demanded for energy decreasing as price increases.
Producer Cost Minimization
- The theory of the producer is used to determine the demand for factors of production.
- Producers minimize production costs by finding input combinations as mathematically, the marginal rate of technical substitution equals slope of cost line.
- Is meant is the locus of efficient combination of inputs which yield output
- Cost line means different combinations of inputs bought given expenditure and price.
Indicators Analyzing Change in Demand
- Three indicators can be used:
- Growth rates
- Demand elasticity
- Energy intensity
- Energy indicators link energy use to GDP and production value which is helpful as a tool for policymakers to predict future developments.
Growth Rates
- Year-on-year growth rate is calculated annually to get historical series:
- a = (Et+1 - Et)/Et a = annual growth in demand, Et+1= energy demand in year t+1 Et= energy demand in year t
- Annual average growth rate provides a comprehensive picture:
- ag = (Et1/Eto)^(1/t1-t0)-1 ag: annual growth rate over a period. Et1: energy demand in period t1 (Ending period) Eto: energy demand in period to (Beginning period)
Demand Elasticities
- Elasticities measure how much demand would change (in percent) if the determining variable changes by 1%.
- et = (ΔECt/ECt) / (ΔΙt/It) EC: energy consumption I: driving variable of energy consumption as GDP, price, income, etc. Δ: change in the variable. t: a given period
- Output or GDP elasticities of energy demand describes change of energy demand for every 1% change in output.
- GDP is positively related to energy demand but the value of elasticity varies by an economy's development stage.
- Developed countries tend to have inelastic demand for income while developing countries have elastic demand.
- Price elasticities indicate how much demand changes for every % change in price with elasticities being negative.
- Short-term price elasticity captures the instantaneous reaction.
- Long-term captures adjustments over time as consumers adjust capital stock, consumption.
Energy Intensities
- Energy intensities measure the energy requirement per unit of a driving economic variable and is equal to energy consumption / value of driving variable.
- Sectors are divided by driving economic variable:
- Whole country: GDP
- Industry: Value added
- Agriculture: Value Added
- Commercial: Value Added
- Transport: GDP
- Households: GDP or Private Consumption
- The purpose is to provide an understandable measure of the economy's performance regarding energy use which is updated on repeat.
- A low energy intensity is desirable and indicates an effective energy infrastructure.
- Reducing energy consumption is helped by improving large scale power plants and targeting energy efficiency.
Energy intensity Trends
- Energy intensity worsens during early industrialization when economic advancement uses equipment of lesser value.
- Energy intensity improves following industrialization as technology and infrastructure improve with cheaper maintenance.
- Lowering EI includes improving efficiency of production and extraction of raw materials.
- Recycling aluminum can dramatically improve El.
- Switzerland and Japan have the best energy intensity through use of least energy to produce GDP.
Drawbacks of using EI include problems related to GDP and energy consumption
- GDP may be understated because underground economies will not be accounted for in market statistics.
- GDP may be overstated or understated in foreign currency due to how it is converted.
- The use of PPP values based on comparison of the "basket of goods” can be used to reconcile.
- Problems with accurate data arise when traditional energies are used in developing countries.
