# Particle Accelerator & Energy Consumption

How much energy is a accelerator using when keeping particles orbits (by constant speed):

for example:

2.99999997 E8 m/s (or topspeed)
2.98000000 E8 m/s
2.97000000 E8 m/s
2.80000000 E8 m/s

Please mention the energy consumption in % relative to the top-speed (I believe it is - 2.99999997 m/s) or in MW relative to the numbers of particles in orbit.
