Energy Transition

Transitioning to Clean Energy Sources: A Global Overview
The energy transition is a crucial component in the fight against climate change, and wind energy plays a vital role in this process as one of the most accessible and eco-friendly alternatives. Our innovative vertical wind turbines play a crucial role in accelerating the transition to sustainable energy, especially in urban and residential areas where clean energy consumption is essential. By integrating reliable and adaptable wind energy solutions, we aim to support the broader shift toward greener energy choices. Below, we provide insights into how countries worldwide are progressing in their energy consumption, highlighting the balance between conventional and alternative sources.
To understand how different countries consume their energy resources and the role renewable sources play in this consumption, we have prepared a visualization of data for 70 countries [1] in 2023. Using Chernoff Faces [2, 3] – visual representations that make complex data more accessible – we illustrate the share of each energy source, from fossil fuels to renewables, in overall consumption. This approach provides a clear picture of the current reliance on alternative energy sources and enables comparisons across countries as they progress toward a sustainable future.

On the Our World in Data website, data is provided on the consumption of energy resources by various countries, including resources such as Oil, Coal, Gas, Solar, Wind, Hydro, Other renewables, and Nuclear. We have assigned these resources to various elements of the Chernoff Face. An additional parameter, R/F, has been added.

R/F

Chernoff Faces corresponding to the boundary values of parameters:

The “Best” boundary corresponds to the maximum values of the parameters Solar, Wind, Hydro, Other renewables, Nuclear, and R/F, and the minimum values of the parameters Oil, Coal, and Gas.

The “Good-Middl” boundary, which marks the division between good and satisfactory parameter values, corresponds to the first quartile Q1 values.

The “Middl-Bad” boundary, which marks the division between satisfactory and unsatisfactory parameter values, corresponds to the third quartile Q3 values.

The “Worst” boundary corresponds to the minimum values of the parameters Solar, Wind, Hydro, Other renewables, Nuclear, and R/F, and the maximum values of the parameters Oil, Coal, and Gas.
