Q

Coal Overview

A
  • Dirtiest Fossil Fuel
  • Coal production is dominated by China, Russia and Australia who between them hold over 60% of the world’s reserves of coal.
    • Majority is from China (42.5% of world total)
    • In 20 years, Asia’s production has doubled to 2 billion tonnes of coal.
  • Asia is also the largest consumer of coal
    • 2 billion tonnes in 2008
  • Previously, many countries in Europe (e.g. UK) were the
    largest producers and also consumers.
    • Heavy deindustrialisation reduced this.

Q

Worldwide Coal consumption

A
  • Declining worldwide consumption
  • Europe 75% use of coal to 10% use of coal
  • In Europe and the USA, the accessible deposits of coal have been exhausted
  • Costs risen - machinery and wages
  • BUT global consumption is still rising
  • May continue to decrease because of environmental concerns and climate change

Q

Problems with Coal

A
  • Huge eco concerns
    • Coal releases the most amount of greenhouse gases
    • Because of the huge link with climate change, HICs are moving away from coal due to global concerns
    • Coal and coal production is locally environmentally damaging
    • Coal dust pollutes the atmosphere, locally, soil, water courses
  • If are u live near coal mines, you may get lung diseases

Q

Cleaning Coal?

A
  • Whilst coal is recognised as being the most environmentally damaging and polluting of all fossil fuels, steps are being taken to mitigate the amount of harm
  • Technologies are currently being developed to prolong coal production such as Carbon Capture and sequestration (CCS) - capture and don’t release it
  • To reduce environmental impact of coal, you need to use more energy

Q

Natural Gas Overview

A
  • Cleanest fossil fuel
  • 1990-2015: production of gas increased from approximately 2,000 billion cubic metres to 3,500 billion cubic metres (risen by 75%)
  • Largest producers - North America and Eurasia
    • USA accounts for over 20% of global production, with Russia producing 19%
  • Production is determined by factor endowment
  • Compared to oil there is a much stronger correlation between gas production and consumption
  • The countries that produce gas and countries closest to these countries consume a lot of natural gas as gas is difficult to transport. It is transported by pipelines’
  • Local demand can easily determine how much is transported

Q

Natural Gas Consumption trends

A
  • Natural gas is considered to be the cheapest and cleanest of fossil fuels, so therefore is the fastest growing
  • Fracking cut USA costs of gas by 50% - technology should expand globally (but local eco concerns)
  • Allowed countries to produce more gas
  • Fracking allowed them to get access to new reserves (new technology) → increased supply of energy → Price of gas fell → Consumption increased
  • This technique offers solution in the short / medium term
  • Unsustainable in the long term due to environmental implications
