Cursor Environmental Impact

Q: What is Cursor's carbon footprint?

Based on the carbon intensity of its inference location (Multi-cloud (Azure, AWS)), each Cursor query produces approximately 0.5g of CO2.

Q: How does Cursor compare to a Google search?

A Cursor query uses 4x more than a traditional Google search in terms of energy consumption. A Google search uses approximately 0.3 Wh, while Cursor uses 1.2 Wh per query.

Q: How much water does Cursor use?

Each Cursor query consumes approximately 4.5 mL of water, primarily used for cooling the data centers that process the request.

Detailed Breakdown

Energy Consumption

Cursor is the most popular AI coding tool, using a mix of models (GPT-4, Claude, custom fine-tunes) depending on the task. A typical code edit or chat turn consumes ~1.2 Wh, though Tab autocomplete uses lighter models (~0.1 Wh). Heavy users may trigger 100+ queries per hour, making Cursor one of the highest-volume AI use cases per user.

Cursor — About

Power Source & Carbon

Cursor routes queries to multiple model providers (OpenAI, Anthropic, custom), inheriting the carbon profile of each. Infrastructure spans Azure and AWS.

Water Usage

At ~4.5 mL per code edit. The aggregate water impact is significant given the frequency of use — a developer using Cursor for 8 hours may trigger hundreds of model calls.

About Cursor

Cursor is a code assistant model from Anysphere, released in March 12, 2024. AI-native code editor — most popular AI coding tool. Each query uses 1.2 Wh of energy and produces 0.50 g of CO₂. That's about 4.0x what a Google search consumes.

These figures are estimates derived from hardware specifications and API benchmarks — Anysphere has not published official energy data for Cursor. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.

Cursor in Context

120 MWh

estimated daily

At global scale

With an estimated 10M+ daily users averaging 10 queries each, Cursor consumes roughly 120 MWh of electricity per day — enough to power 4000 homes.

10.9 kWh

per year

Your yearly Cursor footprint

At 25 queries per day, your annual Cursor usage consumes 10.9 kWh — roughly what a fridge uses in a month. That produces 4.6 kg of CO₂.
