Energy Transition Story
Assignment 3: Storytelling with Open Data (40%)
Course: 2510 – Data Visualisation
Student: Animesh Tyagi (ID: 2510)
Dataset: OWID Global Energy Dataset
Hosted: Posit Cloud (Shareable URL)
Format: Quarto Reveal.js – 10 slides, 1080p
Slide 2: Data Overview & Setup
- The dataset covers annual energy data from 1965 to the most recent year.
- Includes both global aggregates and country-level breakdowns.
- Key variables: primary energy consumption, renewables consumption, population.
- Some countries have missing population values; filtered where needed.
- Ready for trend analysis and comparative insights.
Slide 3: Global Renewables Share
Slide 5: Country Case Study: Australia vs Germany
Slide 6: Key Global Leaders
- Norway leads the world in 2023 with a 72.09% share of its primary energy from renewables.
- Sweden (53.89%) and Brazil (50.33%) are the only other countries above 50% renewables.
- Denmark (42.74%) and New Zealand (42.27%) complete the top five performers.
- European nations dominate the top ten, with 7 of the 10 spots, underscoring the region’s clean-energy focus.
- The global average renewables share in 2023 is just 14.56%, highlighting how far most countries still have to go.
