The world is currently dependent on fossil fuels, which power our homes, offices, schools, and manufacturing plants. Fossil fuels are affordable and reliable, but they release harmful CO₂ emissions into the atmosphere. Renewable energy sources are on the rise, but they currently only contribute 11.4% of the total global energy. The question remains: can renewable energy sources replace fossil fuels?

Nuclear energy is the only solution capable of replacing fossil fuels at scale
Nuclear energy, on the other hand, has already proven its ability to replace fossil fuels at scale. After the 1973 oil crisis, France began replacing almost all its fossil plants with new nuclear plants. The French finished the job in less than 15 years, and today, excluding hydropower, France has the most reliable, cleanest, and cheapest electricity in Europe. Nuclear power is also the safest energy source, with fewer than 200 deaths from radiation accidents in the last 70 years, compared to 8 million deaths each year from fossil fuel pollution.
Nuclear power is also more reliable, cheaper, and less environmentally damaging than any other electric power system. It generates no CO2 and produces less toxic waste than even solar power. The waste from a new nuclear plant is also far less problematic than that of spent solar panels.
While some may argue that nuclear energy is not the answer to solving climate change due to the human impacts of nuclear power, the scientific reality is that the rising generation of nuclear innovation is safe. The risk profile of new reactors and other technologies in development is very low, especially relative to the risks of climate change fallout and the health risks of burning fossil fuels.

Fossil fuels still dominate the energy market, accounting for 84.3% of all energy consumption
Fossil fuels, including oil, coal and gas, still dominate the energy market, accounting for 84.3% of all energy consumption. They are used to power homes, offices, schools, prisons, public buildings and manufacturing plants. Fossil fuels are a reliable and affordable energy source, but they release harmful CO₂ emissions into the atmosphere.
Renewables currently contribute only 11.4% of the total global energy. However, they can effectively replace fossil fuels, creating crucial environmental, social and economic benefits. Renewables can replace fossil fuels in key areas such as power, transport and thermal comfort.
A full transition from fossil fuels to renewable energy will not happen overnight, but the need is growing more urgent. A complete transformation of our energy infrastructure is critical to achieve the replacement of fossil fuels.
Nuclear energy is the only solution capable of replacing fossil fuels at scale. After the 1973 oil crisis, France replaced almost all its fossil plants with nuclear plants, and now has the most reliable, cleanest and cheapest electricity in Europe.

Renewables can effectively replace fossil fuels, creating crucial environmental, social and economic benefits
Renewable energy sources can effectively replace fossil fuels in key areas that keep industries and countries running, from power to public and private transport to thermal comfort. For example, solar farms have allowed fossil-fuelled plants to cut back and save emissions on sunny days. However, they haven't been able to replace them 24/7 and cannot do so by themselves. Currently, renewables contribute only 11.4% of the total global energy, while fossil fuels account for 84.3% of all energy consumption.
A complete transformation of our energy infrastructure is critical to achieving the replacement of fossil fuels. This includes transitioning away from coal, gas, and oil, which currently supply over 80% of our energy. While this transition is already in progress, it needs to be expedited.
Nuclear energy is another option for replacing fossil fuels at scale. After the 1973 oil crisis, France began replacing almost all its fossil plants with new nuclear plants, and today, excluding hydropower, France has the most reliable, cleanest, and cheapest electricity in Europe.

Solar farms have allowed fossil-fuelled plants to cut back and save emissions on sunny days
Renewables currently contribute only 11.4% of the total global energy, while fossil fuels, including oil, coal and gas, still dominate at an overwhelming majority, accounting for 84.3% of all energy consumption. A complete transformation of our energy infrastructure is critical to achieving the replacement of fossil fuels.

A complete transformation of our energy infrastructure is critical to achieve the replacement of fossil fuels
Renewables can effectively replace fossil fuels, creating crucial environmental, social, and economic benefits. However, a full transition from fossil fuels to renewable, clean energy will not happen overnight. It is a process that needs to be expedited. Alternative energy sources can replace fossil fuels in key areas, from power to public and private transport to thermal comfort.
One example of a successful transition is France, which began replacing almost all its fossil plants with new nuclear plants after the 1973 oil crisis. The French finished the job in less than 15 years, and today, those plants provide more than 70 percent of France’s electricity. France now has the most reliable, cleanest, and cheapest electricity in Europe.
However, it is important to note that renewable energy sources currently contribute only 11.4% of the total global energy. Fossil fuels, including oil, coal, and gas, still dominate at an overwhelming majority, accounting for 84.3% of all energy consumption. To achieve a complete replacement of fossil fuels, a significant shift in our energy infrastructure is necessary. This includes investing in renewable energy sources, improving energy efficiency, and implementing policies that support the transition to a cleaner energy future.
