I meant 8 times as much energy. KE goes with velocity^2, so travelling twice as fast requires 4 times as much energy just for the speed, and then wind resistance is related to v^2 as well, so it's probably close to 8 times as much energy to actually cycle twice as fast. Test it out!

I'm starting to record all my trips, and as I get fitter I'll be able to cycle faster.
