energy
global energy supply and demand
energy consumption and supply vary globally
physical and political factors effect energy supply
increasing energy consumption results from development and rising populations
impacts of energy security
exploration of difficult and enviromentally sensitive areas
environmental costs
oil spill would be catastrophic
strict controls are needed
equipment may sink during summer thaw
food production
industrial output
conflict
economic costs
exploitation is difficult and expenisve
people demand high wages
long distances increase transport costs
stratergies to increase energy supply
using renewable and non-renewable sources of energy
non-renewable
nuclear
fossil fuels
renewable
biomass
wind
HEP
tidal
geothermal
wave
solar
natural gas
advantages
