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 construct a suitable graph illustrating the estimated global energy consumption by 2030 based on the data provided, follow these steps:
-
Graph Paper: Take a sheet of graph paper for accurate representation.
-
Label the Vertical Axis: The vertical axis will represent the percentage of energy consumption. Start from 0% at the bottom and label increments suitable for the values (up to at least 40%).
-
Label the Horizontal Axis: The horizontal axis will represent different energy sources: Renewable Energy, Nuclear/Electric Power, Oil, Coal, and Natural Gas. Ensure these labels are centered below each category on the axis.
-
Plot the Data: Represent the consumption percentage for each energy type with bars or circles. Each energy category should be clearly defined with appropriate height representing its percentage consumption.
-
Add a Title: Include a descriptive title for the graph, such as ‘Estimated Global Energy Consumption by 2030’.
-
Color or Shading: Optionally, use different colors or shading patterns to visually distinguish between different energy sources in the graph.
Step 2
In your answer book, explain briefly what is meant by the term renewable energy.
Answer
Renewable energy refers to energy sources that are naturally replenished on a human timescale. This includes sources such as solar, wind, hydroelectric, and geothermal. Unlike fossil fuels, which can be depleted and contribute to environmental degradation, renewable energy sources produce little to no greenhouse gas emissions when generating electricity.
Characteristics of Renewable Energy:
-
Sustainability: Renewable energy sources can be utilized continuously without the risk of exhaustion.
-
Environmental Impact: They contribute to reducing pollution and are less harmful to ecosystems compared to traditional energy sources.
-
Diversity of Sources: This category includes various forms such as solar power harnessed from the sun, wind power generated from air currents, and biomass derived from organic materials.
In summary, renewable energy plays a crucial role in creating a sustainable energy future, reducing reliance on finite resources, and combating climate change.
