The Future of Data Centres

Data farms using as much energy as small cities should be on the time table. We need to ask ourselves, do i work with the most efficient algoridems are there? Do i use the cloud service providers that are the most efficient? I believe in the coexistence of machines and humans at the level of science which is not like fictional films but more realistic. In countries where we haven't had a digital infra-ditalized by technology, why don't they use it? So modern systems adopt these steps through intermediary steps without going through government or businesses.
