Seminar 8
Energy Scarcity
influenced by demand(the more demand the higher price)
higher prices reflect scarticty
influenced by supply (physical supply of energy)
incentives to improve energy efficiency
substitutiuon alternativec
impacts
own price (oppurtunity costs) is inelastic
The UK is not completely coal free
history of energy
picking up wood
with the begining of agriculture crop waste used for burning
the industrial revolution
coal
timber scarcity around the late 18th century in the UK
industrialization
better transportation and manufacturing because of coal
this model got adopted by the US and other european coutnries
in the US wood went out of fashion around 1920s
coal and other sources of energy get into the energy mix

History of electricity provision
energy consumption and economic growth
richer coutnries consume more energy
as countries get better off countries consume more energy and then it pleatoes
todays countries that are at the same level of GDP per capita as the US in the 50s are using much less energy than the US at the same level in the 1950s
effciiency is key
for example biomass is really inefficient as a source (much less efficient than coal or other sources)
e.g. China and India are using energy much and much more efficiently that the US at the same level of GDP/capita => they are already as less enegry enegry intensity that US while they are at even lower GDP levels and they are decreasing intensity more rapidly than the US did
Drivers of the energy transition
Energy Ladder (household level)
depending on income people change their sources of energy
this model is wrong
when changing from one source to another you have to also change appliances
security and unreliability of different sources
modern sources are higher costs and so are used less
preferences for using certain fuels -> food tastesbetter from ccarchcoal
energy sources change on urban vs rural areas
income
energy acess,
energy prices
Policy Options
stay with biomass but use more efficiently trough technogy
reduces usage, health effects etc
