Their models aim to provide actionable intelligence to governments, corporations, and researchers as the world transitions to a more sustainable energy system.

This article will summarize NASA’s latest worldwide energy predictions through 2100 and analyze the implications of different energy resource mixes for the future of humanity and the planet.

Current Worldwide Energy Usage

Globally, fossil fuels like oil, coal, and natural gas currently make up the vast majority of total energy consumption. In 2021, oil accounted for around 33% of total worldwide energy use. Coal constituted 27% and natural gas made up 24%. Meanwhile, renewables only provided around 5% of global energy. Nuclear generated about 4%. Other smaller sources rounded out the rest.

Fossil fuels dominate in part because they have provided inexpensive, abundant energy to rapidly industrialize and meet the energy needs of a growing world. However, the dependence on fossil fuel based energy has also led to concerns around air pollution, climate change, and energy security as reserves deplete.

Oil is crucial for the transportation sector globally. Natural gas provides heating, electricity and industrial energy. Coal remains a major electricity source, especially for developing nations building out power infrastructure.

Going forward, renewable energy sources like solar, wind and hydro power are projected to meet increasing shares of global demand. And the electrification of vehicles and other technologies could transition transportation away from oil. But the sheer scale of today’s fossil fuel infrastructure and use presents challenges for significantly reducing emissions quickly.

Projected Global Energy Demand

NASA has modeled future global energy demand based on factors like population growth, economic development, and energy efficiency improvements. Their models attempt to provide an objective, data-driven estimate of how much energy the world will need in the coming decades.

According to NASA’s projections, global energy demand is expected to grow by 50% between 2018 and 2050. This represents an average annual increase of 1.3%. While renewable energy is expected to grow faster than fossil fuels, fossil fuels will likely still account for over half of energy use in 2050.

Most of the increased energy demand is expected to come from developing nations as they industrialize and increase standards of living. However, population growth and economic expansion will also drive growth in developed regions like North America and Europe. Key factors that could impact demand growth are the rate of energy efficiency improvements, economic growth rates, and the speed of transitioning the transportation sector to electric vehicles.

NASA’s models account for a wide range of scenarios. Their baseline projection sits in the middle, with high and low estimates varying global energy demand in 2050 by 15%. While projections are not guarantees, NASA provides data-driven models to help policymakers and businesses plan for the future.

Fossil Fuels

NASA projections show that Earth’s reserves of oil, natural gas, and coal are immense but finite. Current proven global reserves of oil total 1.7 trillion barrels, enough to last about 50 years at today’s consumption rates. Reserves of natural gas are larger, estimated at 7,300 trillion cubic feet, sufficient for 55 years. Coal reserves are the largest, totaling about 1 trillion tons, or 130 years worth at current usage levels.

However, accelerating energy demand, especially from developing countries, threatens to deplete reserves faster than new ones can be found. According to NASA models, world energy consumption is likely to grow from 18 terawatts currently to around 30 terawatts by 2040 and 46 terawatts by 2100. This implies fossil fuel usage would also climb dramatically. Without major improvements in extraction technology or new large discoveries, oil supplies could start facing deficits as early as 2030. Coal shortages could emerge by 2050, and natural gas by 2060.

Rising fossil fuel prices from depletion may spur a faster transition to renewable energy and nuclear power. But abundant coal reserves could enable continued heavy reliance on this carbon-intensive fuel without technological advances to capture and sequester emissions. Thus NASA research underscores the importance of policies that accelerate clean energy deployment and improve efficiency in order to mitigate environmental impacts.

Renewable Energy Potential

According to NASA’s research and modeling, renewable energy sources have immense potential to meet global energy demands in the coming decades. This is especially true for solar and wind power.

NASA estimates that the potential solar energy that could be utilized is over 23,000 Terawatt hours per year globally. For context, the total worldwide energy consumption in 2020 was about 159,000 Terawatt hours. So solar alone could fulfill over 10 times total global energy needs. The southwest United States, Mexico, South America, Africa, the Middle East, India, and Australia have particularly high solar energy potential.

Wind power also has great promise, with NASA models showing between 72 and 161 Terawatt hours available per year globally on land areas alone. Major potential exists across the Midwest United States, Patagonia, the Northern Andes, and much of Eurasia. Additionally, offshore wind farms could provide even more clean energy.

Other renewable sources can also generate significant electricity. Hydroelectric power provides about 16% of world energy currently. Geothermal energy has large potential in regions with volcanic and seismic activity such as Iceland, East Africa, and Indonesia. Bioenergy from plants and organic waste is another growing field, especially with advanced biofuels.

Overall, NASA research indicates that a diverse mix of renewable sources can likely meet most of the world’s energy demand in the future, especially when combined with greater efficiency.

Nuclear Energy Outlook

NASA projects that nuclear power will continue to play an important role in meeting the world’s energy needs in the coming decades. While the share of nuclear energy has declined in some countries like Germany, it continues to supply 11% of the world’s electricity. With over 440 nuclear reactors operating globally, nuclear power remains one of the largest sources of low-carbon energy.

New nuclear reactor designs focus on improved safety, efficiency, modularity, and lower costs. Several startups are developing small modular reactors that can be mass-produced in factories and deployed rapidly. Some advanced designs use alternative fuels like thorium rather than uranium. According to NASA’s projections, next-generation nuclear reactors combined with existing plants can provide a sizeable portion of future energy demand if policies support their development.

However, challenges remain for nuclear power such as high upfront capital costs, waste disposal, and public perception. NASA expects most growth to occur in countries like China and India that have rising energy needs and existing nuclear infrastructure. Overall, NASA foresees nuclear power remaining an important electricity source for decades but highlights the need for innovation and supportive policies to realize its full potential.

Energy Storage Advancements

NASA scientists have made key contributions to improving energy storage technologies in recent years. Although batteries have advanced tremendously, energy storage remains a crucial challenge in transitioning to renewable energy and reducing carbon emissions.

At NASA’s Jet Propulsion Laboratory, researchers are developing new battery chemistries and technologies to enable longer-duration energy storage. These advances could dramatically improve the viability of solar and wind power. Key areas of focus include lithium-ion batteries, lithium-sulfur batteries, and flow batteries.

One promising concept from NASA is lithium-sulfur batteries, which have a much higher theoretical energy density than lithium-ion. Researchers have developed prototypes that have achieved over 500 charge-discharge cycles. With further refinement, lithium-sulfur could become a commercially viable technology for grid-scale energy storage.

Additionally, NASA is researching innovative battery management systems to optimize charging and discharging. New battery management algorithms and thermal control techniques can minimize degradation and extend battery lifespans. Applying aerospace expertise to energy storage is accelerating the progress. According to NASA, their developments could enable safer, lighter, and longer-lasting batteries.

Energy Efficiency Improvements

NASA predicts that improvements in energy efficiency will play a major role in meeting future energy demand sustainably. With growing global populations and economies, energy demand is projected to increase substantially in the coming decades. However, through technological advances, smarter energy use, and conservation efforts, the energy needed to power homes, businesses, industries, and transportation can be significantly reduced.

NASA foresees continued innovation leading to major gains in energy efficiency across all sectors. For example, buildings can be designed to maximize natural lighting, heating, and cooling needs. Smart home devices and building automation systems can help reduce energy waste. Industries can adopt processes that require less energy input per unit of output. Cars, trucks, planes, and ships can be engineered for optimal fuel economy. Even simple behavioral changes like turning off lights, adjusting thermostats, and purchasing energy efficient appliances can cumulatively make a big difference.

According to NASA’s projections, energy efficiency improvements have the capability to curb global energy demand growth by one-third by 2040. This would significantly reduce the need for additional fossil fuel production and combustion, thereby helping mitigate climate change risks and impacts. Thus, energy efficiency represents one of the most cost-effective and attainable solutions for sustainably meeting the world’s energy needs this century and beyond.

Policy and Behavior Changes

NASA research indicates that in addition to developing new energy sources, changes in policy and human behavior will be critical to meet future energy demands in a sustainable way. Widespread adoption of energy efficiency measures, such as installing better insulation and switching to LED lighting, can significantly reduce energy usage. Governments also have a role to play by implementing policies that encourage renewables over fossil fuels, such as tax incentives and feed-in tariffs. However, individual lifestyle changes are just as important. If people switch to more plant-based diets, adopt sustainable transportation methods like walking, biking, and public transit, and reduce unnecessary energy usage, it would lessen the strain on natural resources. NASA scientists emphasize that an “all of the above” strategy is required, combining policy, technology, and behavioral solutions to transition to a cleaner energy system.

Conclusion

In summary, NASA’s predictions for worldwide energy resources and power indicate that fossil fuels will continue to be a major part of the energy mix in the coming decades. However, renewable sources such as solar, wind, hydropower and biofuels have enormous potential for growth and are predicted to supply an increasing share of global energy demand.

Nuclear power is also forecast to expand its capacity, aided by new reactor designs and improved waste management technology. Advancements in energy storage solutions will help overcome intermittency issues with renewables and boost their viability.

Significant gains in energy efficiency across sectors like transportation, manufacturing and buildings will also curb energy usage per capita. Policy, regulation and consumer behavior shifts towards sustainability will further accelerate the transition to a diverse energy portfolio with a larger share of renewables.

In conclusion, while fossil fuels will remain relevant, NASA forecasts a steady shift towards a more balanced worldwide energy system relying on a variety of traditional and renewable resources.
