Many people consider electronic technologies "green." But broadcasting data wirelessly takes much more energy than transmitting data on copper wire or optical fiber. A mobile call requires three times as much energy as a corded landline call. To keep air conditioned, data centers require the equivalent of 30 nuclear power plants. If data centers were a country, they would rank fifth in use of energy.
For the most part, modern technologies expand our use of energy. They do not curtail it.
