2
Energy security The uninterrupted physical availability of energy products on the market, at a price which is affordable for all consumers Risks include –Disruptions to supply of fossil fuels –Insufficient investment –Technical failure –Civil unrest or blockades
3
Reduce and replace Reduce More efficient use of energy and demand reduction comes first Replacement options Renewables, including biofuels Carbon capture and storage Nuclear power
4
Short term considerations Transport fuel accounts for around a third of current world energy consumption UK uses liquid fuel for most of its transport energy needs Currently no alternatives to liquid fuel for air transport
5
How might biofuels help? “Biofuels contribute to energy security by increasing the diversity of supply choices and introducing a component of supply that is not necessarily import dependent” An alternative to petroleum as liquid fuel for transport Can add to energy diversity and reduce risks Attractive as home-grown source of energy in some countries Like oil, biofuels can be stored
6
Possible impact Biofuels could make a potentially important contribution to future global energy supply mix UK target is 5% of total transport fuel from renewable sources by 2013 Energy security concerns must be integrated with other factors, e.g. reduction of greenhouse gas emissions
