Ranked: The Top 10 Countries by Energy Transition Investment

More than 130 countries have set or are considering a goal of net-zero emissions by 2050.

Achieving net-zero on a global scale, however, requires $125 trillion in climate investment by 2050, according to research commissioned by the United Nations Framework Convention on Climate Change (UNFCCC).

While that level of investment hasn’t been achieved yet, it’s ramping up. In 2021, the world spent $755 billion on deploying low-carbon energy technologies, up 27% from the year prior.

This graphic highlights the top 10 countries by low-carbon energy investment in 2021 using data from BloombergNEF.

Energy Transition Investment by Country

The top 10 countries together invested $561 billion in the energy transition, nearly three-fourths of the world total.

South Korea 🇰🇷$13B1.7%
Brazil 🇧🇷$12B1.6%
Spain 🇪🇸$11B1.5%
Total$561B74.3%

China increased its overall energy transition investment by 60% from 2020 levels, further cementing its position as a global leader. The country’s wind and solar capacity increased by 19% in 2021, with electrified transport also accounting for a large portion of the investment.

Next, the U.S. invested $114 billion in clean energy last year, up 17% from 2020. Several European countries also made the top 10 list, with Germany, U.K., and France rounding out the top five. In total, European countries invested $219 billion in the energy transition.

Which Low-Carbon Technologies are Attracting Investment?

While the top 10 countries provide an overview of where investments are being made, it’s also interesting to see which sectors are seeing the biggest influxes of capital.

Here’s a breakdown of energy transition investment by sector in 2021:

Technology/SectorTotal Investment in 2021 (US$)% change from 2020
Renewable energy$365.9B6.8%
Electrified transport$273.2B76.7%
Electrified heat$52.7B10.7%
Nuclear$31.5B6.1%
Sustainable Materials$19.3B141.3%
Energy Storage$7.9B-6.0%
Carbon capture & storage$2.3B-23.3%
Hydrogen$2.0B33.3%
Total$754.8B26.8%

Renewables accounted for nearly 50% of total investment in 2021. However, electrified transport drove much of the growth as several countries charged ahead in the shift to electric vehicles.

Nuclear power also racked up roughly $32 billion in investments, as conviction grows that it can deliver reliable, carbon-free electricity. But the biggest overall percentage gain was seen in sustainable materials including recycling and bioplastics, which saw investment activity more than double in 2021.

Given that the dawn of clean energy is still in its early hours, technologies in the sector are constantly evolving. As the race to net-zero continues, which energy technologies will draw even more investment in the future?

The Scale of Global Fossil Fuel Production

Fossil fuels have been our predominant source of energy for over a century, and the world still extracts and consumes a colossal amount of coal, oil, and gas every year.

This infographic visualizes the volume of global fossil fuel production in 2021 using data from BP’s Statistical Review of World Energy.

The Facts on Fossil Fuels

In 2021, the world produced around 8 billion tonnes of coal, 4 billion tonnes of oil, and over 4 trillion cubic meters of natural gas.

Most of the coal is used to generate electricity for our homes and offices and has a key role in steel production. Similarly, natural gas is a large source of electricity and heat for industries and buildings. Oil is primarily used by the transportation sector, in addition to petrochemical manufacturing, heating, and other end uses.

Here’s a full breakdown of coal, oil, and gas production by country in 2021.

Coal Production

If all the coal produced in 2021 were arranged in a cube, it would measure 2,141 meters (2.1km) on each side—more than 2.5 times the height of the world’s tallest building.

China produced 50% or more than four billion tonnes of the world’s coal in 2021. It’s also the largest consumer of coal, accounting for 54% of coal consumption in 2021.

Mapped: Biggest Sources of Electricity by State and Province

The U.S. and Canada rely on a different makeup of sources to generate their electricity. How does each state and province make theirs?

Mapped: Biggest Sources of Electricity by State and Province

On a national scale, the United States and Canada rely on a very different makeup of sources to generate their electricity.

The U.S. primarily uses natural gas, coal, and nuclear power, while Canada relies on both hydro and nuclear. That said, when zooming in on the province or state level, individual primary electricity sources can differ greatly.

Here’s a look at the electricity generation in the states and provinces of these two countries using data from the Nuclear Energy Institute (2021) and the Canada Energy Regulator (2019).

Natural Gas

Natural gas is widely used for electricity generation in the United States. Known as a “cleaner” fossil fuel, its abundance, coupled with an established national distribution network and relatively low cost, makes it the leading electricity source in the country.

In 2021, 38% of the 4120 terawatt-hours (TWh) of electricity generated in the U.S. came from natural gas. Not surprisingly, more than 40% of American states have natural gas as their biggest electricity source.

Here are some states that have the largest shares of natural gas-sourced electricity.

State/Province% of Electricity from Natural Gas
🇺🇸 Rhode Island90.9
🇺🇸 Delaware85.8
🇺🇸 Massachusetts76.9
🇺🇸 Florida73.9
🇺🇸 Mississippi72.1

In Canada, natural gas is only the third-biggest electricity source (behind hydro and nuclear), accounting for 11% of the 632 TWh of electricity produced in 2019. Alberta is the only province with natural gas as its main source of electricity.

Nuclear

Nuclear power is a carbon-free energy source that makes up a considerable share of the energy generated in both the U.S. and Canada.

19% of America’s and 15% of Canada’s electricity comes from nuclear power. While the percentages are close to one another, it’s good to note that the United States generates 6 to 7 times more electricity than Canada each year, yielding a lot more nuclear power than Canada in terms of gigawatt hours (GWh) per year.

As seen in the map, many states and provinces with nuclear as their main source of electricity are concentrated in the eastern half of the two countries.

In the U.S., Illinois, Pennsylvania, and South Carolina are top producers in terms of GWh/year. Illinois and South Carolina also have nuclear as their primary electricity source, whereas Pennsylvania’s electricity production from natural gas exceeds that from nuclear.

The vast majority of Canada’s nuclear reactors (18 of 19) are in Ontario, with the 19th in New Brunswick. Both of these provinces rely on nuclear as their biggest source of electricity.

Renewables: Hydro, Wind and Solar

Out of the different types of renewable electricity sources, hydro is the most prevalent in North America. For example, 60% of Canada’s and 6% of the U.S.’s electricity comes from hydropower.

Here are the states and provinces that have hydro as their biggest source of electricity.

State/Province% of Electricity from Hydro
🇨🇦 Manitoba 97
🇨🇦 Newfoundland and Labrador95
🇨🇦 Quebec94
🇨🇦 British Columbia87
🇨🇦 Yukon80
🇺🇸 Washington65
🇺🇸 Idaho51
🇺🇸 Vermont50
🇨🇦 Northwest Territories 47
🇺🇸 Oregon46

Wind and solar power collectively comprise a small percentage of total electricity generated in both countries. While no state or province relies on solar as its biggest source of electricity, Iowa, Kansas, Oklahoma, and South Dakota rely primarily on wind for their electricity, along with Canada’s Prince Edward Island (PEI).

Coal and Oil

Coal and oil are emission-heavy electricity sources still prevalent in North America.

Currently, 22% of America’s and 7% of Canada’s electricity comes from coal, with places such as Kentucky, Missouri, West Virginia, Saskatchewan, and Nova Scotia still relying on coal as their biggest sources of electricity.

Certain regions also use petroleum to generate their electricity. Although its use for this purpose is declining, it is still the biggest source of electricity in both Hawaii and Nunavut.

Over the next few years, it will be interesting to observe the use of these fossil fuels for electricity generation in the U.S. and Canada. Despite the differences in climate commitments between the two countries, lowering coal and oil-related emissions may be a critical part of hitting decarbonization targets in a timely manner.
