Nuclear power is becoming more prominent
Nuclear power is becoming an increasingly prominent energy source as fossil fuels begin to disappear. Nuclear energy is the only alternative base system capable of providing electricity continuously, 24 hours a day, and is carbon-free, making it vital to our clean energy future.
Nuclear power currently accounts for about 10% of global electricity generation, rising to almost 20% in advanced economies. It is the second-largest source of low-carbon electricity, providing about a quarter of the world's carbon-free energy. Fourteen countries in 2023 produced at least a quarter of their electricity from nuclear sources, with France obtaining around 70% of its electricity from nuclear energy.
Nuclear power has been generating an increasing share of the world's electricity in recent years, growing by 3.3% in 2018 due to new capacity in China and the restart of four reactors in Japan. As of 2023, there are 415 civilian nuclear reactors in the world, with 66 more under construction and 87 planned. The number of nuclear reactors is expected to reach a record high in 2025 as Japan restarts production, maintenance work is completed in France, and new reactors begin commercial operations in China, Europe, India, and Korea.
Nuclear power's ability to provide low-emission, dispatchable, and flexible power boosts its value to the global energy system. As decarbonization increases, these attributes become even more important and valuable to power systems. Nuclear power plants also contribute to electricity security by keeping power grids stable and complementing decarbonization strategies, as they can adjust their output to accommodate shifts in demand and supply.
While nuclear power has faced challenges, including high upfront costs, long lead times, and a poor record of on-time delivery, its prominence is increasing due to its ability to produce emissions-free power and the need to reduce dependence on fossil fuels.

Fossil fuels are non-renewable resources
The formation process of fossil fuels began hundreds of millions of years ago, when the Earth had a different landscape. Wide, shallow seas and swampy forests covered the planet, and plants, algae, and plankton thrived in these ancient wetlands. Through photosynthesis, these organisms absorbed sunlight and created energy. Over time, they died and drifted to the bottoms of seas and lakes, where their stored energy was preserved. The weight of rocks and sediment piling on top of them, combined with the Earth's heat and pressure, transformed these organic materials into fossil fuels.
The finite nature of fossil fuels means that they will eventually run out. While the exact date is unknown, estimates range from 2052 for oil deposits to 2168 for coal reserves. The World Coal Association estimates that at current rates of production and consumption, coal reserves will last about 150 years. However, factors such as increasing global demand, rising fuel prices, and environmental concerns are accelerating the transition away from fossil fuels.
As fossil fuels become depleted, the world is turning to alternative energy sources. Nuclear power is gaining prominence as a continuous and carbon-free source of electricity, currently contributing 11% of the world's electricity. Renewable energy sources like solar, wind, and hydro power are also being developed, but they currently meet a small proportion of global energy needs. The future of energy may also include thorium-based nuclear reactors, as thorium is more abundant in nature than uranium.
The transition away from fossil fuels is crucial not only due to their limited supply but also because of their environmental impact. Burning coal and oil releases particles that pollute the air, water, and land, contributing to climate change and endangering our future. As such, there is a growing recognition of the need to reduce our consumption of fossil fuels and embrace renewable and nuclear energy alternatives.

Renewable energy is becoming more affordable
Fossil fuels are non-renewable resources that were formed millions of years ago. They include natural gas, coal, and oil, which are used to meet the ever-growing global demand for energy. However, the reserves of these fuels are finite and will eventually run out. While the exact timeline for their depletion varies, it is estimated that known oil deposits will last until 2052, natural gas will last up to 53 years, and coal reserves will suffice for 114 to 150 years. The transport industry's reliance on oil accelerates its depletion, with estimates suggesting it may run out in 50 years.
As fossil fuels deplete, the search for alternative energy sources intensifies. Nuclear power is one option, offering continuous electricity generation and contributing 11% of the world's electricity. Uranium, with a potential lifespan of over 150 years, and thorium-based nuclear reactors are being explored. However, nuclear waste storage remains a challenge.
Renewable energy sources, such as solar, wind, and hydro, are also gaining traction. The cost of renewable energy technologies has decreased significantly, making them more affordable and attractive to consumers. For instance, the price of electricity from utility-scale solar photovoltaics has declined by 88% in 15 years, and wind energy costs have also decreased. China, in particular, has made substantial additions to renewable energy capacity, driving down global costs.
The declining prices of renewable energy technologies are attributed to various factors, including economies of scale in production, technological and engineering advancements, increased durability, market competition, and declining capital costs. These factors collectively contribute to a continuous price decline, making renewable energy sources increasingly competitive with fossil fuels.
The transition to renewable energy sources is further accelerated by the rising cost of fossil fuels and the negative environmental impact of coal, which is the most polluting fossil fuel. As a result, 81% of new renewable energy sources can produce power more cheaply than fossil fuels. This "seismic shift" towards renewables is expected to continue as countries strive to fulfill their pledge to triple renewable energy capacity by 2030.

The transport industry is driven by oil
The transport industry is heavily reliant on oil, with petroleum products accounting for about 89% of the total US transportation sector's energy use in 2023. This includes motor gasoline, aviation gasoline, distillate fuels (mainly diesel), jet fuel, residual fuel oil, and propane. Gasoline is the dominant transportation fuel in the US, followed by distillate fuels and jet fuel. The US is not alone in its dependence on oil for transportation, as aviation fuel use worldwide is almost 100% fossil fuels, and shipping fuel use is predominantly heavy fuel oil, marine gas oil, and marine diesel oil.
The transportation sector's high consumption of oil is a significant contributor to global warming and environmental degradation. As a result, there is a growing emphasis on transitioning to alternative energy sources, such as renewable and nuclear power. However, the transport industry's reliance on oil is deeply entrenched, and the development of renewable energy sources to meet the sector's high energy demands remains a challenge.
Oil is transported through various methods, including pipelines, tanker trucks, rail transport, and oil tankers. The choice of transportation method depends on factors such as the quantity of oil being transported and the distance to be covered. For instance, tanker trucks and rail transport are typically used for shorter distances and smaller capacities, while pipelines and oil tankers are more suitable for large-scale transportation over longer distances.
The extraction and refining of oil are also integral components of the oil industry. Oil is often extracted from remote locations, and advancements in exploration and extraction techniques have increased the accessibility of oil reserves. However, the refining process, which converts crude oil into usable petroleum products, remains a critical step before distribution to consumers.
While the transport industry is currently driven by oil, the finite nature of fossil fuels and the environmental concerns associated with their use highlight the urgency of exploring sustainable alternatives. The transition to renewable energy sources, such as solar, wind, and hydro power, is already underway, but it will take significant time and effort to fully replace the transport industry's reliance on oil.
