What we do see is that the Trendnet TEG-S50G only uses 3W of power, while the D-Link DGS-1005D "Green" switch uses 5W of power. The difference is only 2W and will probably cost you in the neighborhood of $0.25 per month extra to run, but the Trendnet switch is "Greener" as it does indeed use less power than the competition.
