Title: What is the link between Energy Production and Global Warming?


1
What is the link between Energy Production and
Global Warming?
2
Energy Production
  • Energy is produced, so we can all have a certain
    lifestyle. We all expect a constant electricity
    supply
  • In the UK, the main source of electricity comes
    from burning Fossil Fuels
  • Electricity can also be made by renewable sources
  • The target in Northern Ireland is to have 12 of
    all energy generated by renewable sources by 2012

3
Energy Production
  • A watt is a measurement of energy
  • Power stations and other energy generating
    devices are measured in megawatts (MW)
  • The largest coal-fired power station in the UK,
    Drax Power Station, Yorkshire produces 4,000MW
    7 of UKs electricity demands (SOURCEDTI)

4
Energy in Northern Ireland
  • There are 3 power stations, producing about
  • 93-97 of our electricity needs
  • Coolkeeragh Power Station, near Londonderry. Uses
    gas to generate electricity
  • Ballylumford Power Station, Island Magee. Uses
    gas to generate electricity
  • Kilroot Power Station, Carrickfergus. Uses coal
    to generate electricity

5
  • - For thousands of years, wood has been a major
    source of energy. Wood is still a major source of
    energy in some countries of the world today, e.g.
    Nepal.
  • - Since the Industrial Revolution, over the last
    200 years, there has been a dramatic growth in
    energy production.

6
  • Over the last 200 years,
  • There has been a greater demand for energy from
    factories, machinery and domestic use throughout
    the world
  • There has been a dramatic population growth

7
  • Over the last 200 years there has
  • therefore been more burning of fossil
  • fuels to produce energy.
  • Main sources used Coal, oil and gas

8
Our society, our lifestyles, our technologies
encourage greater use of fossil fuels
  • Fossil fuels are efficient at producing
  • energy BUT there are problems
  • Greenhouse gases, e.g. CO2 are released when they
    are burnt
  • Limited supply of these resources
  • They are only found in certain parts of the world

9
What is Global Warming?
  • Global Warming is an increase in
  • temperatures
  • This happens because of the
  • Greenhouse Effect
  • http//www.bbc.co.uk/climate/evidence/greenhouse_e
    ffect_img.shtml

10
Greenhouse Effect
  • Greenhouse gases (CO2, methane, nitrous oxide
    CFCs),
  • released by us go up into the Earths
    atmosphere, which stop some of the sun-rays from
    leaving the Earths atmosphere making the Earth
    warmer

11
What releases Greenhouse gases? What causes
Global Warming?
  1. Natural processes, e.g. the release of CO2 from
    melting permafrost
  2. The burning of fossil fuels
  3. Emissions from vehicles

12
  • Is there a link between Energy Production and
    Global Warming?
  • YES
  • And while the majority of our energy is produced
    by fossil fuels that emit CO2 and other
    greenhouse gases this will continue

13
  • There is research and evidence to prove global
    temperatures increased by 0.5oC during the 20th
    century
  • The IPCCs Report, 2nd Feb. 2007, suggest a
    possible temperature rise by the end of this
    century from between 1.10C and 40C

14
  • Global Warming means that we are
  • experiencing Climate Change (a change
  • in what the climate we would usually
  • expect)
  • We are and will experience Climate
  • Change because of Global Warming

15
  • There has been a long debate about the
  • impact of humans on global warming.
  • The IPCCs Report, 2nd Feb 2007, states,
  • The higher degree of certainty that changes are
    down to human activities up from at least 66
    in 2001 to at least 90 now is significant

16
  • Achim Steiner, from the UN stated,
  • Friday, 2 February 2007 may go down in history
    as the day when the question mark was removed
    from the question of whether climate change has
    anything to do with human activities

17
Warming Signs IPCC Report, 2 Feb 2007 states the
evidence for global warming includes,
  • 11 of the last 12 years are among the warmest on
    record
  • Oceans have warmed down to 3,000 metres
  • Mountain glaciers and snow cover have declined

18
Warming Signs IPCC Report, 2 Feb 2007 states the
evidence for global warming includes,
  • Satellites have seen an acceleration in sea level
    rise
  • More intense and longer droughts have been
    observed
  • Arctic cover is shrinking in depth and in extent

19
What will Global Warming mean for us?
20
What will it mean for the UK?
  • Hotter/drier summers and wetter/stormier winters
  • As temperatures and rainfall patterns change,
    this will have an impact on our lifestyle and
    biodiversity
  • During the summer, air-conditioning will be
    needed more widely
  • More flooding in the winter

21
What will it mean for the UK?
  • Lack of water may become more common at certain
    times of the year
  • Less need to travel to Spain to get a sun-tan!
  • Mosquitoes may become common in the UK
  • Birch trees may find it difficult to survive in
    the changing climate

22
What will it mean globally?
  • Sea level rise, due to melting of ice
  • May see more extreme weather
  • More drought during the summers
  • More intense hurricanes, due to warmer oceans
  • More intense Asian monsoon

23
What will it mean globally?
  • Low-lying land areas will be flooded as sea
    levels rise
  • Large coastal cities may also be flooded, e.g.
    Calcutta, India and Shanghai, China leading to
    large population movements

24
What will it mean globally?
  • More extreme weather, e.g. hurricanes and
    droughts will have large social, economic and
    environmental impacts
  • Economic impacts governments will need to spend
    money on buildings, flood defenses and
    infrastructure
  • What are other possible economic impacts?

25
What will it mean globally?
  • Economic impacts as agriculture adapts to
    change in growing seasons, strains of diseases
    and transport costs
  • Economic impacts as certain businesses may need
    to change location
  • Change in lifestyle as people work to reduce CO2
    emissions

26
A Global Issue, demands Global Action
  • What is being done?

27
What are governments doing about it?
  • There have been global meetings to discuss issues
    of climate change
  • At these meetings each country is represented and
    they talk about policies and some agreements have
    been signed
  • As Global Warming involves all countries, it is
    important that all countries work together to
    help reduce its impact

28
Kyoto Protocol, 1997
  • The Kyoto Protocol is a significant agreement,
    which was signed by the majority of countries in
    1997
  • Signing, meant that a country was agreeing to
    reach targets
  • Targets to reduce the production of greenhouse
    gases in their country

29
Kyoto Protocol, 1997
  • 141 countries signed, agreeing to cut greenhouse
    emissions by 5.2 by 2012

30
The Worlds biggest polluter the USA did not
sign
  • Why do you think the USA did not sign?
  • What impact does this have on reducing the
    effects of global warming?

31
What does this all mean for us?
  • It does mean that we will experience some of the
    effects of Climate Change
  • It also means we need to think about how we live
    and what we can do to reduce our impact
  • Each of us can choose to live more wisely by,
    e.g. - not wasting energy, becoming more
    energy efficient
  • - encourage the use of more renewable energy

32
A small action makes a difference
  • Our World is changing
  • - We all have the ability to make a difference
  • What are you going to do?
