Not everyone needs it to survive, but many do. It is needed to survive if you live in a climate that gets very cold or very hot. It's needed to survive if you rely on medical equipment powered by electricity. It's needed to survive if you rely on a refrigerator to store food. Of course needs are on a spectrum, but its frustratingly disingenuous to suggest that google.com is comparable to electricity in terms of need, it's obviously not.
