yep, takes more energy to move you faster, BAR NONE. Okay 90 miles per hour downhill with a tail wind could possibly be better than 65 MPH uphill with a headwind...

It's a matter of physics: more air to push thru takes more energy. period. There must be some equations to google that will show this?

Cheers,
