To answer your question; NO

What the electric company charges you is by Kwh (Kilowatthour)

240 Volt uses 1/2 the Amps a 120 Volts fixture would but to get the same power or watts... it's a wash. Now 240 Volt maybe slightly more efficient but this will not save you lots of $$$ on your electric bill.

Formula: Watts = Amps x Volts

Example 400 Watt Fixture running on 120 volts uses 3.33 Amps

Same 400 Watt Fixture on 240 volts uses 1.66 Amps

Unfortunately the Electric company charges you for the watts.

so this means you could get more lights on a low amp circuit?

yes you can run twice the load on a 230v circuit than you can on a 115v circuit of the same amperage. However 230v circuits are usually rated for 30-40 amps.

Your KVAR (reactive component) will decrease with higher voltage, but very little.

240v motors/wiring use less copper and are less expensive.
