Source: Energy Production & Changing Energy Sources
The “Our World In Data” website provides a visualization of global energy production over the past two centuries. The data is broken down into specific energy sources and shows how their composition has changed over the years as the primary energy source transitioned from “Biofuels” in the 19th century to “Crude Oil” for much of the 20th century.
This chart shows how our energy production has changed over the last century and shows the gradual adoption of renewable energy sources in recent decades. This visualization is effective in the sense that it presents the data in a clear, understandable form.
In the expanded mode, viewers can see what percentage of the global energy production comes from each energy source, although this view does hide the awe-inspiring near-exponential growth in energy consumption over time. It shows the slight dip in nuclear energy more clearly than in the previous view and makes viewers wonder if this trend is likely to continue – many nuclear reactors have been shut down in recent years due in part to safety concerns and cheaper natural gas.
This graphic appears to be intended for the general public and does not advocate for any particular energy policy. The goal seems to be to simply present the raw data to a wide audience, allowing the viewers to draw their own conclusions regarding what the future for energy sources will look like.
