With many countries and companies pledged to reduce emissions, the clean energy transition seems to be an inevitability. And that transition will undoubtedly have an impact on employment.
New sources of power don’t just require new and updated equipment, they also require people to operate them. And as demand for cleaner fuels shifts attention away from fossil fuels, it’s likely that not every sector will see a net gain of employment.
This graphic shows projected global employment growth in the clean energy sector and related areas, under announced climate pledges as of 2021, as tracked by the IEA’s World Energy Outlook.
Which Sectors Will Gain Jobs By 2030?
In total, the clean energy transition is expected to generate 10.3 million net new jobs around the world by 2030.
Though fuel generation will definitely be affected by the clean energy transition, the biggest impact will be felt in modernizing energy infrastructure:
Clean Energy Jobs By Sector (to 2030) | Jobs Gained | Jobs Lost | Net Job Shift |
---|---|---|---|
Efficiency | 3.2M | 0 | 3.2M |
Cars | 2.6M | 0 | 2.6M |
Power generation | 2.6M | -0.3M | 2.3M |
Grids | 1.6M | 0 | 1.6M |
Bioenergy | 1.2M | 0 | 1.2M |
End-use renewables | 1M | 0 | 1M |
Innovative technologies | 0.9M | 0 | 0.9M |
Critical minerals | 0.2M | 0 | 0.2M |
Coal | 0 | -0.6M | -0.6M |
Oil and gas | 0 | -2.1M | -2.1M |
Total | 13.3M | -3.0M | 10.3M |
In order to properly utilize the new sources of energy, the largest expected job gains are in electrical efficiency, power generation, and the automotive sector. Combined with modernizing the grid, they make up 75% of the 13.3 million in new job gains expected.
Comparatively, new energy sources like bioenergy, end-use renewables, and supply chain resources like innovative technologies and critical minerals combine for 3.3 million jobs. That offsets the 2.7 million jobs expected to be lost in fossil fuel sectors, plus an additional 0.3 million lost in power generation.
But it’s important to note that these expected employment changes are under announced climate pledges as of 2021. The IEA has calculated that in a full net-zero clean energy transition, the estimated quantity of jobs gained and lost would more than double across almost all sectors, with a net addition of 22.7 million new jobs.
Regardless of which path is closest to the reality, it’s clear the job landscape in energy and related sectors will be shifting in the coming years, and it will be interesting to see how and when such changes materialize.

Charted: The Safest and Deadliest Energy Sources
What are the safest energy sources? This graphic shows both GHG emissions and accidental deaths caused by different energy sources.

Charted: The Safest and Deadliest Energy Sources
Recent conversations about climate change, emissions, and health have put a spotlight on the world’s energy sources.
As of 2021, nearly 90% of global CO₂ emissions came from fossil fuels. But energy production doesn’t just lead to carbon emissions, it can also cause accidents and air pollution that has a significant toll on human life.
This graphic by Ruben Mathisen uses data from Our World in Data to help visualize exactly how safe or deadly these energy sources are.
Fossil Fuels are the Highest Emitters
All energy sources today produce greenhouse gases either directly or indirectly. However, the top three GHG-emitting energy sources are all fossil fuels.
Energy | GHG Emissions (CO₂e/gigawatt-hour) |
---|---|
Coal | 820 tonnes |
Oil | 720 tonnes |
Natural Gas | 490 tonnes |
Biomass | 78-230 tonnes |
Hydropower | 34 tonnes |
Solar | 5 tonnes |
Wind | 4 tonnes |
Nuclear | 3 tonnes |
Coal produces 820 tonnes of CO₂ equivalent (CO₂e) per gigawatt-hour. Not far behind is oil, which produces 720 tonnes CO₂e per gigawatt-hour. Meanwhile, natural gas produces 490 tonnes of CO₂e per gigawatt-hour.
These three sources contribute to over 60% of the world’s energy production.
Deadly Effects
Generating energy at a massive scale can have other side effects, like air pollution or accidents that take human lives.
Energy Sources | Death rate (deaths/terawatt-hour) |
---|---|
Coal | 24.6 |
Oil | 18.4 |
Natural Gas | 2.8 |
Biomass | 4.6 |
Hydropower | 1.3 |
Wind | 0.04 |
Nuclear energy | 0.03 |
Solar | 0.02 |
According to Our World in Data, air pollution and accidents from mining and burning coal fuels account for around 25 deaths per terawatt-hour of electricity—roughly the amount consumed by about 150,000 EU citizens in one year. The same measurement sees oil responsible for 18 annual deaths, and natural gas causing three annual deaths.
Meanwhile, hydropower, which is the most widely used renewable energy source, causes one annual death per 150,000 people. The safest energy sources by far are wind, solar, and nuclear energy at fewer than 0.1 annual deaths per terawatt-hour.
Nuclear energy, because of the sheer volume of electricity generated and low amount of associated deaths, is one of the world’s safest energy sources, despite common perceptions.
