EnEfficient PDriver‘16 the energy problem – a range of opinions green enthusiast: sun and wind offer plenty of energy, no nuclear, no fossil, skepticism on tech technology enthusiast: fast reactors, fusion etc. ; optimism about technologies contemplative: technological development is too fast, consequences not predictable, go slower!

EnEfficient PDriver‘16 What is the impact on Particle Accelerators? for each new generation of accelerator facilities we want better flux, rate, brightness, luminosity.  typically needs more power! acceptance of these projects by authorities and the public becomes increasingly difficult.  Thus we need to work on that: – Improve efficiency of accelerators – Demonstrate efforts to improve efficiency to funding organisations / to public – Adapt our facilities to new sustainable energy production

EnEfficient PDriver‘16 Energy management example: CLIC Study on standby modes Andrea Latina, CERN CLIC project predicts large power for 3TeV case: 580MW idea: prepare standby modes for high consumption times during day; relatively fast luminosity recovery from standby (challenging) model calculation includes standby power, startup times result of model with 2 standbys during day:
