It wasn’t so very long ago that communications were largely limited to living beings, whether it was birds, whales, dogs, or people. Our devices were largely mute, performing functions when requested by a button or switch, but otherwise isolated from each other. The development of high-bandwidth wired and wireless communications over the past 2 decades has led to a corresponding transformation with the development of devices that communicate and often act without human intervention. While we are still a long way from Skynet, ubiquitous connectivity is enabling a wide range of possibilities that can help reduce our energy demands in the coming years.
Connected Thermostats, Cars, and More
The old-fashioned set it and forget and even the newer programmable thermostats are being supplanted by wireless, cloud-connected versions like the Nest. In place of a simple mechanical thermocouple, these newer units include sensors to detect motion, light, and humidity, as well as Wi-Fi connections, to the Nest servers to take advantage of big data machine learning and remote control from smartphone apps. By tracking usage patterns and local weather conditions, these thermostats automatically create custom control profiles to provide optimum comfort and minimize energy use.
Ever since the advent of the modern plug-in electric vehicle (PEV) at the turn of the last decade, many of these vehicles have been able to connect to remote servers to get localized electric utility rates. When plugged in at night, they can delay charging until off-peak rates begin, reducing the load on the grid and saving costs for owners. Beginning in 2016, the first cars will start rolling out with vehicle-to-vehicle communications systems that enable cars to broadcast safety-related messages to other nearby vehicles. According to Navigant Research’s Connected Vehicles report, about 80%–90% of new light duty vehicles in North America and Western Europe are expected to be using the technology by 2025.
Researchers, including those at the Detroit technology incubator, NextEnergy Center, are working on new ways to connect these and many other disparate systems to leverage even more information and harness the energy storage in idle PEVs for additional savings. Among the numerous projects at NextEnergy are studies of vehicle-to-building (V2B) and microgrid systems. A small house at the center has been equipped with a direct current wiring system and appliances that enable easier and more efficient energy transfer between the rooftop solar panels, the interior of the house, and the battery electric vehicle parked outside. Another study is developing a model for how many PEVs would be needed to get an optimum balance between vehicle cost and energy cost savings from reducing peak demand for commercial buildings.
The NextEnergy Center will host a 1-day conference on September 9, 2015 called the V2B Mashup. The event includes panels and presentations with speakers from Cisco, General Motors, Visteon, the U.S. Department of Energy, DTE Energy, and more. Seating is limited and online registration is available at www.nextenergy.org/v2bmashup.
