    4. 4. How does it create energy?
    5. 5. How does it create energy?• SOLAR:• *Photovoltaic systems -These are solar panels hat convert sunlight directly into electricity, by end of 2002 1500MW installed globally• *Thermal Power Plants - total global installed capacoty at end of 2002 was 64MW, most in form of 9 power plant in Mojave Desert. Parabolic trough technology is used to collect sun’s rays and steam is generated at 400 degrees to drive turbines & this is enough to meet demand of more than half a million people• *Solar Towers -Idea is to build large area of greenhouse with a very tall tower in the middle, the hot air in greenhouse would rise rapidly up tower, driving turbines on the way.

    20. 20. Positive impacts:• generate no air pollution during operation, the primary environmental, health, and safety issues involve how they are manufactured, installed, and ultimately disposed of• stabilises the economy as it does not rely on oil which is in high demand• increased home safety as it is not unstable, and there is no risk of explosion or poisoning from its use.
    21. 21.

    23. 23. Negative
    24. 24. Negative• It is unreliable as there is no solar power at night and wind power varies• Solar energy can be costly as the technology needed to develop solar energy is extremely expensive and manufacturing a solar panel requires expensive materials.• Solar radiation can be efficiently absorbed only during daytime, but the demand for the energy it generates is continuous, day and night.• Wind turbines require a large amount of space and are unsightly (visual pollution)

    29. 29. TYPE OF ENERGY COAL
    30. 30. HOW DOES IT CREATE ENERGY?•The energy in coal originally came from the sun.•Carbon dioxide from the air was built into carboncompounds that became coal.•We release the energy in coal by heating it whichmakes the molecules and atoms move faster.•This causes some of the electrons to jump out.•The heat releases the potential energystored in the coal and changes it intokinetic energy.•This is used to drive the engines andturbines.
    31. 31. WHERE IS IT FOUND?Coal is mainly found in North America, Russia, China, Asia and Oceana
    32. 32. WHICH COUNTRIES USE IT?The top 10 coal users are...1) China - 1,310,000,0002) United States - 1,060,000,0003) India - 339,000,0004) Russia - 298,000,0005) Germany - 265,000,0006) South Africa - 170,500,0007) Japan - 149,500,0008) Australia - 144,170,0009) North Korea - 103,600,00010) Ukraine - 97,200,000
    33. 33. POSITIVE IMPACTS•In many countries coal is the primary source offuel at a relatively low cost and can easily be used inhomes, industry and for power generations.•Coal reserves are an easy fossil fuel to sell to othercountries.•Coal uses technology that is easily understood andused by us.•More advanced technology will provide us with awider range of hydrocarbon productsfrom oil.
    34. 34. NEGATIVE IMPACTS•Coal is the most polluting source of energy.•Environmental Legislation in a number of countries has required coal-burning power plants to reduce their pollutants such as nitrogenoxides and sulphur dioxides by installing building-sized scrubbers andcatalytic units.•This does not stop the carbon dioxide being released into theatmosphere.•This amounts to nearly 2 billion tonnes of carbon dioxide each yearfrom US coal power plants only.•Coal mining is dangerous for examplethe mining in Chile where 33 miners were trapped for more than 2months.•The waste from coaluse includes fly ash, bottom ash, fines,water treatment sludge and air treatmentsludge and contaminated water.The solid waste has to be disposed of insecure landfill sites.
    35. 35. OIL
    36. 36. Fact File Oil is extracted by fractional distillation it is a fossil fuel found in many countries around the world. It comes from the remains of plants and animals(plankton) that died in ancient seas (600 million years ago) Over the years organisms decayed: with little oxygen they mixed with the sediments forming fine grained shale. As new sedimentary layers were deposited they exerted intense pressure on the source rock.
    37. 37. Where is it found? Oil is formed under the crust of the earth due to immense heat and pressure.
    38. 38. What countries use it? Texas, california in the states Russia Saudi Arabia 2006- Asia pacific region consumed 29.4%. North Iran America 29.6%. Africa 3.3%. Iraq South/Central America 6.2% Nigeria Venezuela
    39. 39. Positive Impacts. Useful on a day to day basis; Transport, machinery Quick Through fractional distillation of oil, one is able to obtain many different types of fuels.
    40. 40. Negative Impacts. Transportation spills Air pollution Toxic waste released, affecting wildlife and causing acid rain. Usurpation of indigenous people’s rights. Disruption of ecosystems.
    41. 41. When will global peak oil production occur. There has been growing concern on when globalproduction will peak and how fast it will decline there after. For example, in the USA, oil production peaked in the 1970s.

    43. 43. EMMA KINGSMAN AND HANNAH BENSONGAS 24
    44. 44. TYPE OF ENERGY- Natural gas is composed mainly ofmethane, it is the least polluting fossil fuel.Due to methane only containing one carbonatom, it produces less fossil fuels thereforebetter for the environment.
    45. 45. WHERE IS IT FOUND?- Production is dominated by Russia andthe USA, together accounting for almost40% of the total gas production in theworld.- However now the Middle East holds thelargest reserves, this is unusualconsidering the main focus used to be oil.
    46. 46. HOW DOES IT CREATE ENERGY?- For the energy in the gas to be released itneeds to be burned, this produces a largeamount of heat.- In natural gas plants, the heat is used topower large turbines called combustionturbines or turn steam turbines by heatingwater.- Natural gas is usually preferred in thesesituations because it produces feweremissions.
    47. 47. WHICH COUNTRIES USE IT? The top natural gas producers - 1) United States 2) Russia 3) Canada 4) Iran 5) NorwayNatural gas exports Natural gas consumption
    48. 48. POSITIVE IMPACTS- Natural gas is more environmentally friendlycompared to oil and coal- Natural gas emits an estimated 70% lesscarbon dioxide than other fuels.- Natural gas burns cleaner than heating oil.- It is the most cost effective as it is inabundant supply.
    49. 49. NEGATIVE IMPACTS- Although it may be more environmentallyfriendly, it is still a non-renewable fuel andtherefore its availability is finite.- Natural gas extraction is damaging thelandscape by leaving large crates within theearth- It is easily explosive if handledimproperly.

    53. 53. HOW DOES IT CREATE
    54. 54. HOW DOES IT CREATE•To make electricity this way, the water is held in a reservoir, behind the dam• The water close to the control gates is where the intake is, and when the controlgates open, the water rushes through the penstock and turns the turbine.•After the water does so, it goes through the outflow into the river. The turbinespins the generator, and the electricity goes to the transformer in thepowerhouse.•Then the transformer transforms the electricity into a usable form, and theelectricity travels through the power lines and goes to homes and businesses.
