1 watt = 1 Joule/sec
60 watts x 900 sec = 54 000 Joule
100 watts x 500 sec = 50 000 Joule
So you use less electrical energy using 100 watt light bulb for 500 seconds.
The burning of coal or natural gas in an electrical generation plant would follow those steps. Starting as a hydrocarbon with lots of potential energy, it would be burned to heat water, which would then boil and create stream would would in turn drive a turbine attached to an electrical generator.
4450 kJ of energy would be released.
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
The electrical energy from the battery can be converted into various forms of energy depending on the device or system it powers. In an electronic device, it may be converted into light (in a flashlight), thermal energy (in a heating appliance), or mechanical energy (in a motor or fan), among others.
A 600W drill would use 600 joules of electrical energy in one second (since 1 watt = 1 joule/second). To calculate the total energy used over a specific period of time, you would multiply the power in watts by the time in seconds.
A loudspeaker or a speaker would transform electrical energy into sound energy by converting electrical signals into vibrations that produce sound waves.

Cars usually run either on gasolene or on natural gas - that is, chemical energy. An electrical car would also have electrical energy stored in its batteries.Cars usually run either on gasolene or on natural gas - that is, chemical energy.

I would guess it refers to transmitting energy using an electrical current.
I would presume it would be chemical energy from burning fuel
The amount of heat energy produced from electrical energy depends on the efficiency of the system. If we assume 100% efficiency, then all 3000 joules of electrical energy would be converted into heat energy. Thus, 3000 joules of electrical energy would produce 3000 joules of heat energy.
A vacuum cleaner typically runs on electrical energy.
You hook them up to an electrical circuit, and the energy would appear as electrical energy that the circuit can then transform into some other format.
When steam is converted into energy, via steam pushing a turbine, turning a generator, making electricity.
4450 kJ of energy would be released.
The generic term for an electrical device that uses and converts electrical energy into other forms of energy would be an electric power converter or simply a converter.
