Conventional power plants

Fossil Resources

Fossil fuels will continue to account for a large share of the future energy mix

  • Natural gas will remain the main fossil energy source, due to its relatively low CO2 emissions,
  • New reserves and production technologies will make gas available for the long term
  • Oil will be used less in power generation, but is the basis for many other products and processes
  • Oil production becomes more complex: more technology per barrel is needed
  • Coal is the most plentiful and widespread fossil energy source
