What You'll Learn
Fossil fuels will run out in 50-150 years
Fossil fuels are non-renewable resources formed millions of years ago. The Earth’s heat, pressure, and the movement of layers decomposed plants and animals, turning them into petroleum, oil, coal, and natural gas. According to estimates, our fossil fuel reserves will be empty in 50-150 years. Oil can last up to 50 years, natural gas up to 53 years, and coal up to 114 years. The exact date is hard to estimate because we find new reserves periodically, but the number of new reserves is low and cannot meet our population's growing energy demands.
The global demand for energy has not yet peaked, and year by year, global energy consumption is getting higher, resulting in the increased use of fossil fuels. Fossil fuel reserves are those that are available for extraction and economically viable to extract. As reserves deplete, they become less available and more expensive. If fossil fuel prices increase enough, companies will be incentivized to tap into other basins of oil or coal that were not previously financially viable.
The good news is that as renewable and energy storage technology continues to improve, becoming more efficient and affordable, governments and organizations are more likely to begin investing in these fossil fuel alternatives. Renewable energy sources already contribute a quarter of the world's energy demand and had the highest growth rate of any energy source in 2017. Nuclear power is also becoming more prominent as fossil fuels begin to disappear, as it is the only alternative base system capable of providing electricity continuously.
However, if we do not successfully transition to renewable energy sources, running out of fossil fuels could have devastating consequences. Fossil fuels currently account for 74% of the world's electricity generation. In the case of extended power cuts, important functions in our society would be threatened, including grocery stores, hospitals, waste management, and more.

Renewables can last billions of years
Electricity has become a necessity in modern life, with many daily activities dependent on it. Power outages can cause significant disruptions, affecting lighting, heating, cooling, water availability, transportation, communication, and even critical functions in hospitals and grocery stores. While running out of electricity may seem like a distant concern, the finite nature of fossil fuels raises concerns about future energy security.
Fortunately, the development and adoption of renewable energy sources offer a promising solution. Renewable energy resources, such as wind, solar, and hydro, are readily available and have the potential to last for billions of years. Unlike fossil fuels, which are limited in supply and contribute significantly to climate change, renewable energy sources emit little to no greenhouse gases. In 2017, renewable energy contributed to about a quarter of the world's energy demand, and its growth rate was the highest of any energy source.
The transition to renewable energy is crucial to address climate change and air pollution. According to the World Health Organization (WHO), approximately 99% of people worldwide breathe air that exceeds healthy air quality limits, resulting in significant health and economic costs. By investing in renewables, we can reduce emissions, improve air quality, and create more jobs. The International Renewable Energy Agency (IRENA) estimates that renewable sources could provide 65% of the world's electricity supply by 2030 and decarbonize 90% of the power sector by 2050.
While renewable energy sources are variable, a combination of wind and solar power can complement each other. Additionally, backup options like hydro and nuclear power can provide constant power when wind or solar energy are insufficient. With further advancements in technology and a growing awareness of the importance of sustainable practices, we can ensure that renewable energy sources will last for billions of years, powering our world long into the future.

Extreme weather is the main cause of power outages
The impact of extreme weather on power infrastructure has been significant, with a 67% increase in major power outages from weather-related events since 2000. The frequency of weather-related power outages varies across regions, with the Northeast and Southeast of the US experiencing the most outages. The length of outages also differs, with tropical storms causing the longest-lasting outages.
The consequences of power outages can be severe, particularly for vulnerable populations. Hospitals, grocery stores, waste management, and heating systems are all dependent on electricity. Extended power outages can impact supply chains, surgeries, respirators, and hygiene. The impact on vulnerable individuals, including the elderly and those with disabilities or medical conditions, can be especially harmful.
Upgrading electrical infrastructure to become more resilient to extreme weather is crucial but challenging. Solutions such as microgrids, renewable energy sources, and underground cabling can enhance resilience and mitigate the effects of climate change. However, rapidly reducing emissions is essential to slow the rate of warming and ease the stress on power grids.
While extreme weather is the primary cause of power outages, it is important to note that other factors, such as human error and ageing infrastructure, also contribute to power disruptions. The increasing frequency and intensity of extreme weather events due to climate change further exacerbate the problem. Therefore, building resilient electrical systems and adapting to changing climatic conditions are essential to minimize the impact of power outages on society.

Urban areas are unprepared for power outages
The world is not going to run out of electricity anytime soon. However, electricity outages are becoming increasingly common due to ageing infrastructure and extreme weather events driven by climate change. Urban areas are particularly vulnerable to power outages because of their heavy reliance on electricity for almost all basic functions.
In the event of a power outage, lighting, ventilation systems, heating systems, and daily appliances would stop working. This would affect transportation, as most urban areas rely on electric-run public transport. Cooking and heating food would also be impacted, as most urban kitchens use electric stoves and ovens. Water availability would also worsen, as water towers run out of water and pressure piping requires electricity to function.
Hospitals and grocery stores are also highly dependent on electricity. Power outages can cause surgeries to be cancelled, respirators to shut down, and hygiene to be threatened. Grocery stores would face issues with the cooling and heating of food products, payment systems, storage management, and supply chains.
European cities, in particular, have been described as poorly prepared for power outages. A sudden and unexplained blackout in Spain in April 2025 caused millions to be affected as substations in Granada, Badajoz, and Seville failed, resulting in a loss of 2.2 gigawatts of generation capacity. Similarly, wildfires in California in January 2025 left 400,000 homes and businesses without power.
To reduce vulnerability to power failures, risk assessments are crucial. Underground cabling, energy storage, and diversified energy mixes can enhance resilience. However, it is also important to prepare for power outages by having canned food, water, and flashlights in storage.

Hospitals, grocery stores, and waste management depend on electricity
While it is unlikely that we will ever run out of electricity on a global scale, it is still possible for localised blackouts to occur, which can have a significant impact on essential services such as hospitals, grocery stores, and waste management facilities, all of which are heavily dependent on a steady supply of electricity.
Hospitals rely on electricity for a wide range of functions, from powering life-saving equipment such as ventilators, heart monitors, and life support machines to maintaining heating and cooling systems, security, lighting, and laboratory specimen storage. To mitigate the risks associated with power outages, hospitals are legally required to have backup power sources, typically in the form of generators, which can provide electricity until the main power is restored. These backup generators are heavily regulated to ensure they meet stringent standards and can be relied upon in emergencies.
Grocery stores and supermarkets are another essential service that depends heavily on electricity. Power outages can lead to significant losses in perishable inventory, particularly fresh produce, meats, seafood, and dairy products, which require constant refrigeration or freezing. To prevent such losses, many grocery chains have invested in backup commercial generators, and some have even rewired their buildings to allow for the quick connection of portable generators. This ensures that their refrigeration, freezing, lighting, heating, and air conditioning systems remain functional during power outages, thus minimising losses and maintaining their ability to serve their customers.
Waste management is another critical function that relies on electricity. While waste-to-energy plants have emerged as a carbon-negative solution for electricity generation, incinerating waste to produce energy, a sudden loss of electricity would impact the ability to process waste effectively. This could result in a buildup of waste, potentially leading to public health and environmental concerns if not adequately managed.
In summary, while a global shortage of electricity is unlikely, localised power outages can have significant impacts on essential services such as hospitals, grocery stores, and waste management facilities. The reliance of these services on electricity underscores the critical importance of maintaining a stable electricity supply and developing robust backup power solutions to ensure the continued functioning of these vital sectors.
