The 2022 Energy Crisis: A Tipping Point for Clean Energy
The global energy crisis of 2022 sent shockwaves in the energy markets.
The crisis acted as a double-edged sword—on one hand, consumers felt the pinch of rising energy prices, but on the other hand, it became a turning point for clean energy, spurring action from governments to cut dependence on fossil fuels.
This infographic from the National Public Utilities Council explores how the energy crisis accelerated the growth of clean energy and nuclear power.
Shockwaves From the Energy Crisis
Although the consequences of the crisis were felt in 2022, its roots go back to 2020 when energy demand dipped during the pandemic.
Following the unprecedented fall in demand, energy markets tightened in 2021 as the global economy rebounded to grow at the fastest pace since 1973. Russia’s invasion of Ukraine escalated the situation, creating a full-scale energy crisis.
As a result, energy prices soared to their highest levels in decades, resulting in rampant inflation worldwide. This highlighted how many nations remained dependent on fossil fuels for energy, in turn creating a tipping point for clean energy.
Clean Energy Turns the Corner
Countries including the United States, the UK, and many EU member states have supercharged clean energy investment over the last two years, partly in response to the energy crisis.
Here’s how global government spending for clean energy has grown since July 2021, as tracked by the IEA:
- $380 billion as of July 2021
- $470 billion as of October 2021
- $714 billion as of March 2022
- $1,215 billion as of November 2022
European countries deployed funding for energy efficiency and low-carbon power generation (through REPowerEU) in response to natural gas supply disruptions from Russia. In August of 2022, the U.S. signed the Inflation Reduction Act into law, providing over $390 billion in clean energy and climate funding.
Consequently, clean energy technologies are growing at an unprecedented rate. The IEA forecasts that global renewable electricity capacity additions from 2022 to 2027 (2,383 GW) will nearly equal all the renewable capacity added between 2001 and 2021 (2,409 GW).
Nuclear Turnaround
Besides renewables, nuclear power has seen a resurgence as governments look for a reliable energy source to replace fossil generation.
Here’s a look at the top 10 countries by the number of prospective nuclear reactors based on the Global Nuclear Power Tracker. This includes announced, pre-construction, and under-construction reactors.
| Country | Number of Prospective Reactors | % of Global Total |
|---|---|---|
| China 🇨🇳 | 103 | 41% |
| India 🇮🇳 | 32 | 13% |
| Russia 🇷🇺 | 30 | 12% |
| Turkey 🇹🇷 | 12 | 5% |
| U.S. 🇺🇸 | 12 | 5% |
| Romania 🇷🇴 | 8 | 3% |
| Poland 🇵🇱 | 6 | 2% |
| UK 🇬🇧 | 6 | 2% |
| South Korea 🇰🇷 | 5 | 2% |
| Bulgaria 🇧🇬 | 4 | 2% |
Besides the countries building and planning reactors, others have reversed their plans to phase out nuclear power:
- Germany extended the lifetime of three plants that were set to shut down in 2022.
- France reversed course to reduce reliance on nuclear, with a plan to build six new reactors.
- Japan accelerated the restarts of nine reactors by winter 2022 and a further seven by summer 2023.
The impact of this accelerated clean energy deployment is already evident.
In 2022, the growth of clean energy technologies helped avoid 550 million tonnes of CO2 emissions, according to the IEA. On the other hand, a decline in nuclear power generation led to an additional 55 million tonnes in CO2 emissions, highlighting the importance of nuclear in reducing emissions.

Which U.S. Utilities Are Investing in Clean Energy the Most?
Decarbonizing the power sector will require significant investments in clean energy as utilities replace existing fossil fuel infrastructure.
In this graphic, we show which U.S investor-owned utilities (IOUs) have allocated the most capital expenditure (CAPEX) toward carbon-free sources of electricity.
The data comes from the latest edition of the Annual Utility Decarbonization Index, created in partnership with the National Public Utilities Council, which quantifies and compares the status of decarbonization among the largest U.S. IOUs.
The Carbon-Free Investment Ranking
The Utility Decarbonization Index ranks companies on six metrics based on the latest available data, specifically those that pertain to their fuel mix, carbon emissions, and decarbonization goals.
The sixth and final metric measures the share of each utility’s planned CAPEX for carbon-free electricity generation, such as nuclear power and renewables.
Here are the top scorers out of the 47 IOUs included in the report.
| Rank | Company | Share of Planned Generation CAPEX Allocated To Nuclear & Renewables |
|---|---|---|

Visualized: Renewable Energy Capacity Through Time (2000–2023)
This streamgraph shows the growth in renewable energy capacity by country and region since 2000.
Visualized: Renewable Energy Capacity Through Time (2000–2023)
Global renewable energy capacity has grown by 415% since 2000, or a compound annual growth rate (CAGR) of 7.4%.
However, many large and wealthy regions, including the United States and Europe, maintain a lower average annual renewable capacity growth.
This chart, created in partnership with the National Public Utilities Council, shows how each world region has contributed to the growth in renewable energy capacity since 2000, using the latest data release from the International Renewable Energy Agency (IRENA).
Renewable Energy Trends in Developed Economies
Between 2000 and 2023, global renewable capacity increased from 0.8 to 3.9 TW. This was led by China, which added 1.4 TW, more than Africa, Europe, and North America combined. Renewable energy here includes solar, wind, hydro (excluding pumped storage), bioenergy, geothermal, and marine energy.
During this period, capacity growth in the U.S. has been slightly faster than what’s been seen in Europe, but much slower than in China. However, U.S. renewable growth is expected to accelerate due to the recent implementation of the Inflation Reduction Act.
Overall, Asia has shown the greatest regional growth, with China being the standout country in the continent.
| Region | 2000–2023 Growth | 10-Year Growth (2013–2023) | 1-Year Growth (2022–2023) |
|---|---|---|---|
| Europe | 313% | 88% | 10% |
| China | 1,817% | 304% | 26% |
| United States | 322% | 126% | 9% |
| Canada | 57% | 25% | 2% |
It’s worth noting that Canada has fared significantly worse than the rest of the developed world since 2000 when it comes to renewable capacity additions. Between 2000 and 2023, the country’s renewable capacity grew only by 57%.
Trends in Developing Economies
Africa’s renewable capacity has grown by 184% since 2000 with a CAGR of 4%.
India is now the most populous country on the planet, and its renewable capacity is also rapidly growing. From 2000–2023, it grew by 604%, or a CAGR of 8%.
It is worth remembering that energy capacity is not always equivalent to power generation. This is especially the case for intermittent sources of energy, such as solar and wind, which depend on natural phenomena.
Despite the widespread growth of renewable energy worldwide, IRENA emphasizes that global renewable generation capacity must triple from its 2023 levels by 2030 to meet the ambitious targets set by the Paris Agreement.
