No...the key word here being "energy".
Energy (or power) is constant in situations such as these, energy is neither created nor destroyed, it just changes forms.
At best, using a perfect transformed at 100% efficiency, one will obtain an equal energy output as the input.
However the 2nd law of thermodynamics states that in reality 100% efficient energy conversions are not possible, so in any conversion some amount of energy is lost to heat.
When dealing with transformers, "step up" or "step down" refers to the voltages, not energy.
Energy is neither increased nor decreased in an ideal transformer, only the voltage and current change, but change in such a way that the power output/input remain constant.

I have read all answers. I wish to stress that energy cannot be stepped up it always steps down as there is always some loss. Energy at best is same in input and out put of any transformer whether step up or step down. This is not only true with transformer but for any transformation/transfer of energy. Either nergy remains locked up or if it has to be used for some purpose then some of it is lost to something which you never intended. That is why we say energy runs downhill. It has a tendency to get converted from more useful form to less useful one. put into one sentence,"Energy has two aspects: Bondage and Wastage!"

Transformers are unique in that there is no power loss (energy) when they are used. With a transformer you can change the voltage either up or down with A/C (Alternating Current) only. Example. THe top wire on an electric pole has about 6800 Volts they feed the transformer with a 3 amp. fuse. The transformer changes it to two wires of approx. 117 volts 200 amps. approx. Service for a house. no loss or gain.

Okie is _almost_ right.
It's true that a transformer can only step up/down voltage and current.
But energy is measured in Joules, not Watts. The Watt is a measure of power.

No, as energy, measured in watts, is basically conserved in a transformer. With a few exceptions, the only manipulation that a transformer can achieve is with the voltage, either up or down.
Well, I stand corrected...

My oversimplified answer got me in trouble, as power ( in watts ) is energy ( in joules ) over a rate of time. Thanks, my bad.

yes sure,
any transformer can be ideally used to either step up or step down....just by interchanging the Primary & secondary.
