Energy supplied to the station = 9 x 10^8 J/s

Efficiency of power station = 34%

That is, only 34% of the energy input is converted to the output and rest is lost in the process.

The amount of useful energy generated = 34% of energy input

= 34% of 9 x 10^8 J/s

= 34/100 x 9 x 10^8 J/s

= **3.06 x 10^8 J/s**.

Thus, the power station produces 3.06 x 10^8 J of useful energy per second.

Hope this helps.
