Cloud computing is currently receiving a lot of attention. With regard to energy, cloud computing should result in lower costs for users and fewer greenhouse gas emissions by streamlining information-crunching into single facilities on speedy machines.
In 2010 Pike Research found that cloud computing could lead to a 38% reduction in worldwide data-center energy use by 2020, compared with the projected growth of data-center energy consumption without cloud computing developments. The impact of the cloud on CO2 emissions is also potentially huge.
