Over 55% of ChatGPT prompts fell into either learning or productivity-related tasks. Users often turn to the chatbot for help understanding concepts, writing emails, summarizing articles, or coding. A wide base of users are using the tool as a digital assistant, tutor, or research aide.
Meanwhile, niche categories like roleplaying and entertainment make up a smaller but meaningful slice. These uses include things like fictional storytelling, game design, and writing fan fiction. Their growth points to ChatGPT’s creative potential beyond functional tasks.
This is the first large-scale analysis that classifies how ChatGPT is actually used, rather than relying on anecdotal evidence or surveys. It also reveals how people across professions—from marketers to software developers—are integrating AI into their daily workflows.
Another key insight? Most people still use the free version of ChatGPT. Only about 10% of the prompts analyzed came from paid users of GPT-4, suggesting that even the free-tier model is driving widespread productivity.

The AI boom is fueling a surge in electricity demand, as data centers consume massive amounts of power to train and run large language models.
Big Tech stand as a major driver of this investment, inking billion-dollar partnerships for greener sources like nuclear and solar. Similarly, China drove almost two-thirds of the world’s renewable capacity additions in 2024 alone.
This graphic shows global electricity investment by sector over the past decade, based on data from the IEA.
Below, we show how clean power is playing a greater role in electricity generation worldwide:
| Sector | 2015 (B) | 2025E (B) | Growth |
|---|---|---|---|
| Solar | $142 | $441 | 211% |
| Grids | $331 | $413 | 25% |
| Wind | $143 | $242 | 69% |
| Coal | $91 | $82 | -10% |
| Nuclear | $45 | $74 | 64% |
| Natural gas | $70 | $70 | 0% |
| Hydro | $59 | $70 | 19% |
| Battery storage | $0 | $66 | n/a |
| Other | $55 | $36 | -35% |
| Total | $936 | $1,494 | 60% |
With investments climbing 211% between 2015 and 2025, solar power has become the world’s fastest-growing power source, projected to reach $441 billion of global investment this year.
Moreover, 75% of renewable capacity additions globally were driven by solar PV in 2024. Notably, solar PV additions jumped by 55% annually in America, 30% in China, and 153% in India.
As we can see, investment in grids is projected to reach $413 billion, up 25% since 2015. Yet, the sector faces numerous bottlenecks including permitting delays and rising equipment costs given high generation demand.
Meanwhile, wind power investment is anticipated to reach $242 billion this year—a 69% increase since 2015. While growth wind power additions weakened in 2024 across key markets like Brazil, Europe, and Brazil, both India and China saw moderate increases over the year.

The rise of Artificial Intelligence (AI) brings enormous benefits, but it also presents challenges—chief among them is the technology’s heavy electricity use.
In partnership with Tema ETFs and the second post in VOLTage week, this visualization highlights how AI is projected to drive growing electricity demand in the years ahead, using data from McKinsey.
Artificial intelligence consumes a lot of electricity for several reasons. Training a model requires processing massive datasets, which demands huge amounts of computing power. The more complex the model, the more energy it takes to run.
Even after training, energy use continues. Every time an AI answers a query—a process called inference—it requires graphics processing unit (GPU) power, adding significantly to energy demand.
Artificial intelligence needs data centers because the models are too large and complex to run on ordinary computers. Data centers provide the specialized GPUs, storage, and networking required for model training and inference. All of this hardware consumes large amounts of electricity to function.
On top of that, cooling systems are needed to keep servers from overheating, which adds even more power use. As AI adoption grows, so does the electricity demand tied to expanding data center capacity.
In 2025, artificial intelligence is already projected to consume more data center capacity than all other workloads combined—44 gigawatts versus 38 gigawatts. That gives AI a 54% share of total capacity.
| Year | AI (gigawatts) | Non-AI (gigawatts) | AI Share |
|---|---|---|---|
| 2025P | 44 | 38 | 53.7% |
| 2026P | 62 | 40 | 60.8% |
| 2027P | 83 | 45 | 64.8% |
| 2028P | 102 | 50 | 67.1% |
| 2029P | 124 | 56 | 68.9% |
| 2030P | 156 | 64 | 70.9% |
Looking ahead, the shift becomes even more dramatic. By 2030, demand from artificial intelligence workloads is expected to reach 156 gigawatts, compared to 64 gigawatts for non-AI uses. At that point, AI would account for nearly 71% of all data center demand.
Electricity demand is set to climb steadily as AI adoption accelerates and data centers expand. This structural growth could create a powerful tailwind for companies involved in power generation, grid infrastructure, and energy technologies. For investors, the sector could offer a compelling long-term opportunity to capitalize on the digital and energy transitions shaping the future.

VOLTage Week: Which sources are likely to drive the upcoming electricity surge?
As the reshoring trend accelerates, millions of manufacturing jobs are returning to American soil. But the benefits aren’t being shared equally across the country.
Reshoring began with supply chain disruptions and sluggish job growth—now it’s gaining momentum with the White House.
When you invest in S&P 500 stocks, you’re gaining exposure to the 500 biggest publicly traded companies in the U.S.—but not equally.
See which goods drive America’s $425B trade deficit—and why they signal key opportunities for U.S. reshoring and domestic investment.
By early 2025, the top ten companies in the S&P 500 made up nearly 40%, marking a high degree of market concentration.
The Magnificent 7 stocks have soared from $1.8T in 2014 to over $18T by 2024—but is their growing dominance making the S&P 500 concentrated?

Coal remains a major U.S. export, even as the domestic energy mix shifts toward natural gas and renewables. In 2024, America exported nearly 100 million tonnes of coal to countries around the world, with a concentration of buyers in Asia.
This visualization breaks down the top destinations for U.S. coal exports last year. The data for this graphic comes from the U.S. Energy Information Administration (EIA). It shows 2024 coal export volumes by destination, measured in millions of tonnes.
India led the pack with 23.4% of all U.S. coal exports, followed by China (11.5%) and Japan (8.4%). Combined, these three Asian countries accounted for nearly 43% of all American coal exports.

Since 2017, Asia has eclipsed Europe as the leading destination for U.S. coal.
In 2024, India alone purchased 22.9 million tonnes. India’s high demand for U.S. coal is driven by a combination of energy security needs, domestic production gaps, and infrastructure limitations. Currently, the country relies heavily on coal to generate electricity—over 70% of its electricity comes from coal-fired power plants.
While several European countries still import American coal, their overall share has declined. The Netherlands remains a key buyer (7.4%), but other nations like Germany, Italy, and Poland account for smaller volumes. The EU’s push to phase out coal and meet climate targets has sharply reduced demand in the region.
Notably, many European buyers now import U.S. coal primarily for metallurgical (steelmaking) rather than power generation uses.
Beyond Asia and Europe, a number of countries in Latin America, Africa, and the Middle East imported smaller quantities of U.S. coal in 2024. Brazil (7.8%) and Morocco (5.6%) were notable non-Asian buyers.

The last time a federal government agency did a count, more than 770,000 people were experiencing homelessness across America.
If put together, they would be larger than Alaska’s population.
The map above visualizes how those 771,000 individuals are distributed, revealing wide disparities between states and regions.
Data for this visualization is sourced from the U.S. Department of Housing and Urban Development.
Its annual Point-in-Time (PIT) survey counts sheltered and unsheltered people experiencing homelessness on a single night each January.
Importantly, these PIT counts are conducted by local Continuums of Care (CoCs) across the country with varying methodology. Some use census counts, others use sampling and extrapolation, or a hybrid of methods.
As a result, they can undercount unsheltered populations, people couch‑surfing, or those avoiding contact.
With 187,000 people unhoused, California alone accounts for roughly one-quarter of the national homeless population.

| N/A | U.S. | USA | 771,480 |
That figure has climbed by nearly 74,000 people since 2015, driven by high housing costs, a shortage of mental-health resources, and persistent income inequality.
Even when controlling for population, the Golden State’s rate of homelessness—4.7 per 1,000 residents—is more than double the U.S. average (2.3).
Naturally, the most populous states in the country will also have the most people experiencing homelessness, but it’s not always a perfect match.
New York ranks fourth in overall residents but second in people experiencing homelessness. In fact, New York City alone shelters more than 100,000 people on any given night.
Washington state is another outlier. It’s the 13th-most-populous state, but records the third-largest homeless count, reflecting the acute affordable housing shortages in Seattle and the Puget Sound region.
Meanwhile, Massachusetts—also facing a severe housing crunch—places fifth by homelessness, ahead of more populous states like Texas and Illinois.
Smaller jurisdictions also stand out when adjusting for scale.
Hawaii and the District of Columbia each report fewer than 12,000 people experiencing homelessness. Yet their per capita rates (8 per 1,000 residents) exceed those of California.
Vermont, Alaska, and Oregon likewise rank high relative to their populations (between 3–5, per 1,000 residents).
