Isagpt uses zero AI Datacenters. Water One day of using AI from Data Centers requires 500 millilitres of water per user just to cool the servers. A person drinks on average 1 Litre of water per day. So AI Data Centers are on track to consume half of our daily water intake. Energy An AI query sent to a Data Center consumes 10x the amount of electrical energy compared to a regular search query. Data Centers currently account for 4.4% of overall electricty consumption. So as AI takes over Data Centers the consumption might reach 10 x 4.4% which is 44%. That is nearly half of all our electricity consumption. Change Be the change you wish to see in the world. Stop using AI Data Centers. Start using Isagpt. Your AI. Your Phone. Your Planet!
