The other half of the challenge lies in building the transport and distribution networks As the low-emission economy evolves, building new generation technologies is just half the challenge

Especially valuable in areas rich with recorded information, analytics relies on the simultaneous application of statistics, computer programming and operations research to quantify performance. Analytics often favors data visualization to communicate insight Analysis is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it.
