Worked Solution & Example Answer:Examine the table above showing estimated global energy consumption by 2030 and answer each of the following questions - Leaving Cert Geography - Question A - 2016
Step 1
Using graph paper, draw a suitable graph to illustrate this data.
Answer
To illustrate the estimated global energy consumption by 2030, a suitable graphical representation is a pie chart or bar graph. The steps to create a bar graph are as follows:
-
Graph Paper: Start with a clean graph paper for clarity.
-
Vertical Axis: Label the vertical axis as 'Estimated Consumption (%)'. Make sure it is easily readable.
-
Horizontal Axis: Label the horizontal axis with the various energy sources: Renewable Energy, Nuclear/Electric Power, Oil, Coal, and Natural Gas. Center the labels for better presentation.
-
Plotting Data: For each energy source, draw bars with heights corresponding to their estimated consumption percentages:
- Renewable Energy: 13%
- Nuclear/Electric Power: 8%
- Oil: 34%
- Coal: 23%
- Natural Gas: 22%
-
Color Coding: Optionally, use different colors for each bar to enhance visual appeal and clarity.
-
Ensure that the entire graph fits well on the page without overcrowding.
Step 2
In your answer book, explain briefly what is meant by the term renewable energy.
Answer
Renewable energy refers to energy that is generated from natural processes that are continuously replenished. This includes energy sources such as:
- Solar Energy: Harnessed from sunlight.
- Wind Energy: Generated from the movement of air.
- Hydropower: Produced from flowing water.
- Biomass: Derived from organic materials such as plants and waste.
- Geothermal Energy: Comes from the heat stored beneath the Earth's surface.
These sources are sustainable, meaning they have a lower environmental impact compared to fossil fuels and are capable of being replenished naturally, thus playing a crucial role in reducing carbon emissions and combating climate change.
