There is a complicating factor on the idea that the heat from the incandesc=
ent bulb now needs to be replaced by another source. Most electricity in No=
va Scotia is still generated by burning fossil fuels. In large power statio=
ns, heat losses and inefficiencies in the steam turbines mean that of the 1=
00% of potential energy in the oil or coal you lose about half of that righ=
t off the top. Transmission losses can easily use up another 10%.
