HANOVER -- A senior HP executive warned Tuesday that the internet of things, which includes cars as participating devices, may consume more energy than the world can muster.

"In five years, there will be 30 billion devices networked in the internet of things," said Oliver Bahns, director automotive at HP Enterprise Services. "The energy requirement will be gigantic." Today already, Bahns said,the public cloud consumes as much energy as Japan.

Bahns said HP is working on a new 'universal memory" architecture that will give computers a five-fold performance increase as well as a 99 percent reduction in energy use.

The new technology, which could be on the market in three-to-five years, would provide carmakers with the ability to keep data locally in the car, rather than in the cloud, the HP executive said. "Clearly fewer data transfers means drastically reduced energy needs."

Bahns also noted that such local storage would offer "the immense advantage of data privacy."

Connectivity, security and privacy are key to an internet of cars, Bahns said. But he also said the auto industry needs to come to grips with issues of system and analytics capacity of their computers. "We don't pay enough attention to how we will get the necessary capacity and the ability to analyze the data that will be generated," he said, adding that this is essential to the success of new mobility.

Bahns spoke at the carIT Congress, which took place during the IAA commercial vehicle fair here. The event is hosted by the automotiveIT Group.
