A 75 bulb will use more electricity.
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

The higher the wattage, the more electrical energy is being used. In a light bulb the electrical energy is converted to EM energy which appears in both visible and infrared parts of the spectrum, so the answer is no, it will be at a higher rate for a 100 watt bulb
energy is energy It does not matter what you are using the energy for, it matters how much energy you are using A 200 watt light bulb uses more energy than a 100 watt light bulb A 200 watt motor uses more energy than a 100 watt light bulb A 200 watt heater uses more energy than a 100 watt light bulb
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
Yes, that is what the numbers mean.
That would be approximately a 30 watt CFL.
60 days is 24x60 hours, so the energy used is 60x24x60 watt-hours, 86400 watt-hours or 86.4 kilowatt-hours or units. If it is a 60-watt incandescent bulb it could be replaced by a 12 watt low-energy bulb, and in the same time that would use only 17.3 units, saving 69 units costing about £10.
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
yes, 4x more
You would need a 12 Watt flourescent bulb
