Nuclear in the Energy Shift
The world’s population is projected to increase to 9.7 billion by 2050 and as the population grows, so will our energy needs.
According to the International Atomic Energy Agency (IAEA), global energy consumption will rise 40% by 2050, and electricity consumption will more than double. Meeting the rising demand for energy while protecting the environment will require clean energy sources that are powerful and reliable—and nuclear fits the bill.
The above infographic from Standard Uranium highlights the advantages of nuclear energy and its role in the clean energy transition.
The Advantages of Nuclear Energy
From cleanliness and reliability to safety and efficiency, seven factors make nuclear power essential to a clean future.
1. Carbon-free Energy
Nuclear power plants generate energy through fission, without any fossil fuel combustion.
As a result, nuclear power has one of the lowest lifecycle carbon dioxide emissions among other energy technologies. In fact, the use of nuclear power has reduced over 60 billion tonnes of carbon dioxide emissions since 1970.
2. Low Land Footprint
Due to the high energy density of uranium, nuclear power plants can produce large amounts of electricity without taking up much space.
A 1,000 megawatt nuclear facility requires just 1.3 square miles of land. For context, solar and wind farms with equal generating capacity can occupy up to 75 times and 360 times more space, respectively.
Of all the advantages of nuclear energy, reliability is one of the most important.
Nuclear facilities can generate electricity round the clock, contrary to solar and wind farms that depend on the weather. In 2020, U.S. nuclear power plants were running at maximum capacity 92.5% of the time, surpassing all other energy sources.
4. Resource Efficiency
All sources of energy use raw materials that help build them or support them, besides the fuels.
These can range from metals such as copper and rare earths to materials like concrete and glass. Nuclear power plants have the lowest structural material requirements of all low-carbon energy sources. They’re not only powerful but also efficient in their material consumption.
5. Long-term Affordability
The high capital costs of nuclear facilities are often cited as a potential issue. However, this can change over time.
In fact, nuclear reactors with 20-year lifetime extensions are the cheapest sources of electricity in the United States. Furthermore, the average U.S. nuclear reactor is 39 years old, and 88 of the 96 reactors in the country are approved for 20-year extensions.
Although conventional beliefs might suggest otherwise, nuclear is actually one of the safest sources of energy.
|Energy source||Deaths per 10 TWh||Type|
|Natural Gas||28||Fossil fuel|
Even including disasters and accidents, nuclear energy accounts for one of the lowest number of deaths per terawatt-hour of electricity.
7. Economic Contribution
Apart from the above advantages of nuclear energy, the U.S. nuclear industry also plays a significant role in the economy.
- The nuclear industry directly employs 100,000 people, and creates thousands of indirect jobs.
- A typical nuclear power plant generates $40 million in annual labor income.
- The nuclear industry adds $60 billion to U.S. GDP annually.
Nuclear is not only clean, safe, and reliable but it also has positive ramifications on the economy.
Nuclear Power for the Future
Transitioning to a cleaner future while increasing energy production may be difficult without new nuclear sources—largely because other renewable energy sources aren’t as powerful, reliable, or efficient.
As the energy shift ramps up, nuclear power will be an essential part of our clean energy mix.
What Electricity Sources Power the World?
Coal still leads the charge when it comes to electricity, representing 35% of global power generation.
What Powered the World in 2022?
In 2022, 29,165.2 terawatt hours (TWh) of electricity was generated around the world, an increase of 2.3% from the previous year.
In this visualization, we look at data from the latest Statistical Review of World Energy, and ask what powered the world in 2022.
Coal is Still King
Coal still leads the charge when it comes to electricity, representing 35.4% of global power generation in 2022, followed by natural gas at 22.7%, and hydroelectric at 14.9%.
Over three-quarters of the world’s total coal-generated electricity is consumed in just three countries. China is the top user of coal, making up 53.3% of global coal demand, followed by India at 13.6%, and the U.S. at 8.9%.
Burning coal—for electricity, as well as metallurgy and cement production—is the world’s single largest source of CO2 emissions. Nevertheless, its use in electricity generation has actually grown 91.2% since 1997, the year when the first global climate agreement was signed in Kyoto, Japan.
Renewables on the Rise
However, even as non-renewables enjoy their time in the sun, their days could be numbered.
In 2022, renewables, such as wind, solar, and geothermal, represented 14.4% of total electricity generation with an extraordinary annual growth rate of 14.7%, driven by big gains in solar and wind. Non-renewables, by contrast, only managed an anemic 0.4%.
The authors of the Statistical Review do not include hydroelectric in their renewable calculations, even though many others, including the International Energy Agency, consider it a “well-established renewable power technology.”
With hydroelectric moved into the renewable column, together they accounted for over 29.3% of all electricity generated in 2022, with an annual growth rate of 7.4%.
France’s Nuclear Horrible Year
Another big mover in this year’s report was nuclear energy.
In addition to disruptions at the Zaporizhzhia nuclear power plant in Ukraine, shutdowns in France’s nuclear fleet to address corrosion found in the safety injection systems of four reactors led to a 4% drop in global use, year-over-year.
The amount of electricity generated by nuclear energy in that country dropped 22% to 294.7 TWh in 2022. As a result, France went from being the world’s biggest exporter of electricity, to a net importer.
Powering the Future
Turning mechanical energy into electrical energy is a relatively straightforward process. Modern power plants are engineering marvels, to be sure, but they still work on the same principle as the very first generator invented by Michael Faraday in 1831.
But how you get the mechanical energy is where things get complicated: coal powered the first industrial revolution, but heated the planet in the process; wind is free and clean, but is unreliable; and nuclear fission reliably generates emission-free electricity, but also creates radioactive waste.
With temperature records being set around the world in the summer, resolving these tensions isn’t just academic and next year’s report could be a crucial test of the world’s commitment to a clean energy future.
How Mine Permitting Delays Impact the Transition to a Green Economy
Currently, the U.S. has a backlog of more than 280 mining projects awaiting permits.
Mine Permitting Delays and the Transition to a Green Economy
Minerals are essential components in many of our daily-use products, such as cell phones, laptops, and cars.
In fact, every American uses nearly 40,000 pounds of newly mined materials each year.
In the United States, however, the current permitting process makes it difficult for businesses to invest in the extraction and processing of minerals, such as copper.
This graphic by Northern Dynasty explores the untapped potential of mineral resources in America.
Copper, a Critical Material
In 2023 the U.S. Department of Energy officially added copper to its critical materials list, following the examples of the European Union, Japan, India, Canada, and China.
Copper is a highly efficient conductor of electricity and is considered vital for clean energy technologies such as solar, wind energy, and electric vehicles.
Green energy-related copper demand is expected to increase by nearly 600% by 2030. In this scenario, the copper market could see an annual deficit of up to about 1.5 million tonnes by 2035.
Despite having more than 53 million tons of copper reserves, the U.S. imports 45% of its copper from other countries.
This is the highest level of import reliance in over 30 years. One of the biggest reasons for this is the country’s mine permitting process.
A Rigorous Mine Permitting Process
Mines are large-scale projects that demand extensive research and policies. As a result, mining projects can take 16 years, or more, to start production.
Currently, the U.S. Bureau of Land Management—which regulates land use in the country—has a permitting backlog of more than 280 mining projects.
In addition, environmental activists have adopted a “not in my backyard” stance towards domestic mining. As a result, companies have often had to resort to litigation to make any progress in the permitting process.
“Activists have weaponized the government bodies that are essential to the safe and responsible development of domestic mines,” says Michael Westerlund, VP Investor Relations at Northern Dynasty Minerals.
The company owns the largest undeveloped copper deposit in the world, named Pebble, in Alaska. Pebble and other five major copper projects totaling over 11 billion tonnes in copper resources have been delayed because of the Federal permitting process.
The Largest Undeveloped Copper Deposit in the World
The Pebble Project has been through a roller coaster of regulatory activity for the past 15 years.
Recently, the U.S. Environmental Protection Agency banned the depositing of mining waste near the mining project in Alaska, citing potential harm to the local sockeye salmon industry.
However, the veto directly contradicts findings from the Federal government that concluded that mining and fishing could coexist in the region.
“Alaska does resource development better than any other place on the planet, and our opportunities to show the world a better way to extract our resources should not be unfairly preempted by the Federal Government”
–Alaska Governor Mike Dunleavy
Projects like Pebble can provide significant economic benefits and support the U.S. transition to a greener future. With the current regulatory uncertainty for U.S. developers, where the much-needed supply of copper will come from is unknown.
