COVER STORY illustrates technologies discussed later in this article and additional "high visibil- ity" technologies to show how the hype cycle works. The central premise of the hype cycle is that visibility does not equate to ef fica- cy. "Fear of missing out" can be an effec- tive marketing tool, but it does not lend itself to reliable investment decisions. Quite often the costs of understanding how a technology is best applied and waiting for its sufficient adoption can significantly outweigh any "first mover" advantages. Figure 1 suggests that the IoT is in its early stages and that some critical sup- porting technologies, such as machine learning, need further development for it to reach its potential. Savings can be achieved from the IoT now; however, or- ganizations need to ensure that any tech- nology chosen has a clearly defined path- way to savings. Too many interdependent technologies are likely to disappoint. Elements of Industry 4.0, such as en- terprise-level 3-D printing, have matured enough to realize some of the envisaged benefits. However, Industry 4.0 relies heavily on the integration of systems, many of which are still relatively new. As with the IoT, effective implementation should rely on clearly identified savings. Further benefits may occur, but organiza- tions should not rely on them to develop business cases. Beyond performance issues Both IoT and Industry 4.0 are not with- out their downsides. Concerns about the security of the devices and their potential to be hijacked persist. For ex- ample, a cyberattack in October 2016, which focused on the U.S. East Coast, was blamed on IoT devices not being equipped to prevent themselves from being hijacked. Such issues are a signifi- cant barrier to the wider adoption of the IoT and Industry 4.0. The IoT is not free either. Beside the capital cost associated with the instal - lation of data collection devices and communications infrastructure, the International Energy Agency has esti - mated that by 2025 the annual standby energy consumption associated with IoT de vices will be equivalent to the electricity production of Portugal. All the above and energy efficiency Proponents of the Internet of Things and Industry 4.0 have identified en- ergy effi ciency as a significant poten- tial benefit. The American Council for an Energy Efficiency Economy es - timated potential savings of 12 to 22 percent of all energy consumed, while the consultant McKinsey suggests 10 to 20 percent energy savings. These are high-level estimates for po- tential future benefits. But what energy cost and consumption savings have existing IoT technologies achieved to date? Where is the potential, and what would be the best way to identify what is relevant to your organization now? Looking through the lens of EN 16247:2014, efficiency opportunities can be broadly classified across building, process, and transport.
