UNA is a modular GPS watch designed for repairability and upgradability, allowing users to replace individual components instead of discarding the entire device. It features advanced heart rate monitoring and is built with sustainability in mind, promoting longevity in use.

Cleaning solar panels can result in a 2%-5% increase in power output. Dust accumulation over time can significantly impact the efficiency of solar energy generation.

Microsoft, Google, and Amazon are projected to spend approximately $1 trillion on AI infrastructure over two years. Data centers operated by these companies are consuming significantly more water than reported, with consumption expected to increase rapidly in the future.

In February 1977, President Jimmy Carter addressed the nation wearing a cardigan to emphasize the importance of energy conservation. He introduced the 'energy transition' program in his Moral Equivalent of War speech, focusing on building a secure domestic energy base.

Data centers consume vast amounts of energy to support increasing digital services and computing power, resulting in significant heat emissions. For example, Equinix, based in California, is the world's largest data center operator and contributes to local temperature increases due to heat generated.

A tool provides estimates of daily energy consumption for various products and activities, measured in watt-hours (Wh). It aims to clarify the differences in energy usage to help users understand the impact of different activities on overall energy consumption.

A hothouse Earth trajectory poses significant risks to global ecosystems and human societies. Research emphasizes the urgency of mitigating climate change to prevent irreversible damage to the planet's climate system.
