No. L2 is a sweet spot between earth, sun and other gravitational bodies. It will be able to hold position without using too much of any fuel. Fuel use will be limited to pointing.

The telescope will actually go into a polar orbit around the invisible L2 point, with the insulated hot side always facing the sun.

I had no idea the speed would be this slow - possibly just a couple hundred mph.

A satellite in low Earth orbit is going 18,000 mph. In geo-stationary orbit, about 7,000 mph.
