Slide 1: Title & Assignment Info

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 4: Median Per-Capita Consumption

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.

Slide 10: Discussion & References

Discussion & Implications
- Renewables rose from <5% to >15% over 60 years
- Per‑capita consumption gaps highlight equity issues
- Policy events (e.g. Paris Agreement) align with growth spurts
- Future focus: storage, grid modernization
