In 2019, 16% of the world’s [primary energy](https://ourworldindata.org/energy-substitution-method) came from low-carbon sources. Low-carbon energy is energy from nuclear and renewables. How has this share changed? Have we made progress on decarbonizing the global energy supply? In the line chart we see how the share of global energy that comes from low-carbon sources has changed over time. It more than doubled in the 20 years from 1970 to 1990: increasing from 6% to 12.6%. At this point, progress appeared to stall for several decades, but is now rising again. <Chart url="https://ourworldindata.org/explorers/energy?tab=chart&facet=none&country=~OWID_WRL&Total+or+Breakdown=Select+a+source&Select+a+source=Low-carbon&Energy+or+Electricity=Primary+energy&Metric=Share+of+total&hideControls=true"/> ## Renewables have grown strongly, but a lot of this has simply offset a decline in nuclear To understand the different rates at which we’ve made progress on decarbonization, it’s useful to break it down into its two components: nuclear energy and renewables. This is shown in the chart. First, we see why we made progress in the 1970s and 80s: nuclear energy was growing quickly, and renewables – mainly hydropower – were also growing, albeit slowly. But throughout the 1990s we see that neither nuclear or renewables made much progress; we were producing more of each source [in absolute terms](https://ourworldindata.org/explorers/energy?tab=chart&facet=none&country=~OWID_WRL&Total+or+Breakdown=Select+a+source&Select+a+source=Low-carbon&Energy+or+Electricity=Primary+energy&Metric=Annual+consumption), but this growth could not outpace the [increased demand for energy](https://ourworldindata.org/explorers/energy?tab=chart&facet=none&country=~OWID_WRL&Total+or+Breakdown=Total&Select+a+source=Low-carbon&Energy+or+Electricity=Primary+energy&Metric=Annual+consumption) overall. Low-carbon energy’s _share_ didn’t increase much. What we see in the first decade of the 2000s is a complete divergence of these sources. Renewables went up. Nuclear went down. Countries stopped investing in new nuclear plants; and some closed down. In absolute terms the [total amount](https://ourworldindata.org/explorers/energy?tab=chart&facet=none&country=~OWID_WRL&Total+or+Breakdown=Select+a+source&Select+a+source=Nuclear&Energy+or+Electricity=Primary+energy&Metric=Annual+consumption) of energy we produced from nuclear stagnated, and for several years actually declined. The world made a lot of progress on renewables over this period. But unfortunately a lot of these gains were offset by the decline of nuclear. Only recently – with a rapid growth in wind and solar power – has low-carbon energy made a comeback. We have continued to make progress on decarbonization, but we could have made much more.
