"Alternative energy sources are always more environmentally friendly than fossil fuels." Discuss (10 marks) by Ms Ava KHALFAOUI https://padlet.com/khalfaouia2/ukfsun4wd5rl en-us 2019-01-07 05:08:50 UTC 2026-03-02 19:09:18 UTC hello@padlet.com Jacqueline https://padlet.com/khalfaouia2/ukfsun4wd5rl/wish/443477209 State the issues regarding global energy demand and consumption trends.
The world depends on fossil fuels for almost everything, e.g. Industry, Agriculture, Transport etc. 

Give examples of alt. energy sources.

Political: Geopolitics of resources. The distribution of non-renewables is uneven so many countries have to import to meet their demands, habitats can be affected by infrastructure such as pipelines. (Canada Trans Mountain Pipeline)

Economic: Alternative energy sources are cheaper but more expensive to set up. Since non-renewables are finite, alternative energy sources are beneficial to the economy in the long run.

Environmental: Although alt. energy sources are often renewable and not finite, they can have other environmental damaging effects other than GHG emissions and such. E.g. Dams can flood vast areas causing habitat loss. Wind turbines are hazardous to birds. (Dams and diversions in the Balkans drying up rivers and damaging wildlife)

Social: alt. energy sources e.g. HEP can flood areas and displace people, potentially driving them to urban areas, which creates other environmental issues. Some people are unhappy about the visual pollution of wind turbines, this dissatisfaction affects the demand of alt. energy.

Conclusion: While alt. energy sources are less environmentally impactful in terms of GHG emission and other impacts on climate change; they can have negative impacts on the environment still, such as habitat loss and damage to wildlife.

Supply will not run out. Although renewable, can be expensive especially when limited by geographic location (Wind, Solar, geothermal, tidal, hydroelectric) so it is not accessible to a large number of people. Does not produce emissions and has low environmental impact. 

Non-renewable:
Not geographically limited so is accessible to most. cheaper than renewable but a lot less environmentally friendly. Limited supply therefore once exhausted, anything relying on the resource will stop, creating further issues
Not only will burning fossil fuels exhaust the resource, but the process of burning them release greenhouse gases, primary and secondary pollutants which contribute to climate change and the enhanced greenhouse effect, as well as tropospheric ozone. 

Give statistics about LIC's + HIC'S and their energy sources percentages over the last decade.

The short term benefit of using fossil fuels is that it boosts economy and meets demand. 
The long term benefit of using alternative energy sources is that it provides sustainable energy security for the future which is renewable and does not contribute to climate change. ]]> 2020-02-11 04:01:55 UTC https://padlet.com/khalfaouia2/ukfsun4wd5rl/wish/443477229 Brandi https://padlet.com/khalfaouia2/ukfsun4wd5rl/wish/443477271 INTRO:
Definitions:
  • Fossil Fuels: A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. 
  • Renewable energy: Energy from a source that is not depleted when used, such as wind or solar power.

PARAGRAPH 1:
Renewable energy positives:
  • Lack of harmful emissions and sustainability
  • Energy sources such solar, wind, and hydroelectric power are extremely clean, with no pollution.
  • Infinite and will not run out, as opposed to non-renewable sources.
  • Renewable energy sources have more than one use, for example tidal barrages can prevent coastal erosion and geothermal springs can be tourist attractions
  • Renewable energy sources have low running costs, such as wind farms. 

PARAGRAPH 2:
Negatives of fossil fuels:
  • Contribute directly to global warming; Releases sulphur dioxide gas when they burn which may lead to acid rain. They also release Carbon dioxide 
  • Non-renewable 
  • Unsustainable; It will eventually run out 
  • Becoming more difficult to extract; this means extraction may become more difficult as mines get deeper 

CASESTUDY:
Renewable energy in Iceland
  • Only country in the world which obtains 100% of its electricity and hear from renewable resources 
  • 87% of its electricity comes from hydro-power and the remaining 13% from geothermal power 
  • Switching from fossil fuels to renewable energy sources have provided Iceland with a stable and economically feasible domestic energy resource 
  • By 1950, 530 small hydropower plants were built in Iceland, creating scattered independent power systems around the country

-  Definition of Alternative energy sources
- Reasoning behind why alternative energy sources are being created, linking into the impact on the environment that fossil fuels have.

Main Body:
Discussing the impact of fossil fuels on the environment: 
- Release of several greenhouse gases resulting in a direct impact to climate change
- Cannot be renewed in the environment (Natural resources are used up until they no longer exist)
-  Currently becoming more and more difficult to obtain resulting in new methods such as fracking which can cause new effects upon the environment

Discussing the impact of renewable energy on the environment:
- Many sources are geographically limited (e.g. Solar farm require lot's of flat and sunny land in order to be more efficient)
- Natural habitats can be disrupted due to the need for certain areas for the energy facilities which can negatively impact the environment

Conclusion:
Renewable energy sources still impact the environment however the long term impacts of non-renewable energy sources far outweigh any environmental impacts from renewable sources.]]> 2020-02-11 04:08:52 UTC https://padlet.com/khalfaouia2/ukfsun4wd5rl/wish/443478715 Chloe https://padlet.com/khalfaouia2/ukfsun4wd5rl/wish/443478767 Intro:
