Step One: Remove Credit Card from wallet.
Step Two: Buy crystal energy with real money.
Step Three: Go to the Energy Depot Trade tab, and rampantly push on Buy Crowns.
Step Four: Go to the Market and admire how energy is now slightly cheaper.
Step Five: Use hard-earned crowns bought with energy to bid less than what people want for energy.
Step Six: When this does not work, go to forums and complain and try to rally mass movement of buying energy with money.
Now if people would read this, the energy prices will lower :D
(Seriously though, those are the real steps people! For the most part anyway)
