With prices of fuel going up every day would it be possible for aircraft manufacturers to make one or both main bogies powered .?
Instead of using the jets would this be possible and would it be economical .
I now see a lot of tugs at Airports pushing and pulling aircraft around to save fuel .
Any thoughts would be appreciated

Doubtful, I would think the weight of making them powered, as well as the extra space would null any fuel saved for taxi. Besides, I think using the engines for taxiing gives them a chance to get everything running and lubricated for the flight, as well as a chance for the pilots to see if everything is normal.

JumboJim747: I dont think Tugs are taxing planes around. They might just from a long term parking area to the gate. Or gate to Parking or Gate to Hanger. But you wont see a tug take a plane to a runway or from the runway to gate unless the plane does not have any power.
"It was just four of us on the flight deck, trying to do our job" (Captain Al Haynes)
It kinda did on my AA 767 flight from JFK to AUA last summer.
The flight boarded and departed 15 mins early.
Then the captain said the tow bar broke and the rampers went out looking for another one.
2 mins later the plane starts pushing back, it does a left 90* turn, then it went foward and the engines were still off.
Then it stopped for a second, then it went foward, then to the right after 20-30 seconds, then straight to the taxi-way entry, I see the tug and the walkers hop on and they took off. That was after 3 to 5 mins since pushback began.
At the same time the engines were starting.

Towbarless tugs are great. I just flew out of A-2 (satellite terminal) at DFW, and the ERJ I was on had a much, much smaller tug than in the picture above. It looked more like a lawnmower. The operator stood on a small platform at one end of the tug and steered with a large wheel. There was no enclosure. It was almost comical to see these tiny tugs pulling ERJs around the ramp area, some of them empty and traveling at a higher speed than would normally be used for taxiing!
The last time I was through that area (about two months ago) they were still pushing back ERJs with towbars.
On another DFW note, I saw the SkyTrain running around the main airport building complex, and was excited to think I might finally get to ride it! Sadly, it was not yet in service, and must have been running just for testing. The 1970's Robo-TrAAin is still in service, for now.
