Which of the following is described as a sustainable event tech development?

• A. Smart wearables for attendee tracking
• B. Energy-efficient lighting: LED displays, laser projection and smart power management systems provide up to 70% lower energy usage.
• C. Hydrogen fuel cell power for venues
• D. On-site composting of food waste.

Answer: (B)

Reducing the energy demands of the technology you use at events is the core idea being tested. Energy-efficient lighting fits this best because it directly lowers how much power the event’s tech draws in real time. LED displays use less energy and last longer than traditional lighting, while laser projection can provide bright, clear visuals with efficient power use. When you combine these with smart power management systems that optimize when devices run, dim lighting when possible, and shut down idle equipment, you get a substantial drop in overall energy consumption—described here as up to 70% lower energy usage. That concrete, scalable reduction in energy use is what marks this as a sustainable event tech development.

Other strategies are certainly part of sustainability, but they don’t describe a direct, technology-focused improvement in energy performance for events in the same way. On-site composting tackles waste, which is important, and hydrogen fuel cell power offers a clean energy option for venues, but they’re broader or different kinds of innovations rather than the specific tech development of making event operations themselves more energy-efficient.
