Worked Solution & Example Answer:Examine the data above showing the electricity generation mix, for the Organisation for Economic Cooperation and Development (OECD) in 2015 and answer each of the following questions - Leaving Cert Geography - Question 7A - 2017
Step 1
Using graph paper, draw a suitable graph to illustrate this data.
Answer
To illustrate the electricity generation mix for OECD in 2015, I would create a bar chart as follows:
- Title the Graph: Clearly label the graph as 'OECD Electricity Generation Mix 2015'.
- Vertical Axis: Label the vertical axis as 'Percentage (%)' to indicate the proportion of each energy source.
- Horizontal Axis: Label the horizontal axis with the energy sources: Hydro, Nuclear, Gas, Coal, Oil, and Other.
- Illustrating the Data: Each bar will represent the percentage contribution of each energy source:
- Hydro: 14%
- Nuclear: 18%
- Gas: 26%
- Coal: 30%
- Oil: 2%
- Other: 10%
- Use appropriate colors for each bar to differentiate the sources.
- Ensure that the bars are correctly scaled and spaced to visually represent the data accurately.
Step 2
Explain briefly one advantage of using energy sources other than fossil fuels.
Answer
One significant advantage of using energy sources other than fossil fuels, such as renewable energy sources (wind, solar, hydro), is their environmental sustainability. Renewable energy sources produce little to no greenhouse gas emissions during operation, which helps mitigate climate change and reduces air pollution. Unlike fossil fuels, which can deplete over time, renewable sources are replenished naturally and can provide a consistent supply of energy without harming the environment.
