Would you use less electrical energy burning a 60 watt light bulb for 900 seconds or a 100 watt light bulb for 500 seconds?

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.

Where do they occur chemical to thermal to current?
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.
How much energy is released by burning methane?
4450 kJ of energy would be released.
Chemical energy from the battery is changed into electrical energyThis electrical energy is then changed to which type of energy?
Your answer would be kinetic energy. -By Olivia Ann Johnson
Is an outlet a source of electricity?
No, an outlet is only a distribution point. A source of electrical energy would be the generation station, wind generator, photovoltaic cells (solar energy panels) or other devices that actually produce electrical energy by changing energy from one type (chemical, solar...) to another.
Can seismic energy be converted into electrical energy?
Sure they can, but it doesn't seem very practical, since probably there would not be much average power (energy per time unit) to be gained.
What type of energy are you using when you turn on a car?
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.

What is electrical energy transmission?
I would guess it refers to transmitting energy using an electrical current.

How is electrical energy in biomass is stored?
In nature, electrical energy is seldom stored as such. Other types of energy would be stored in biomass - mainly chemical energy - but not a significant amount of electrical energy.
What is an example of electrical energy changing to kinetic energy?
An electric motor or a fan would be an example of electrical energy changing to kinetic energy
What kind of energy does a spaceship use?
I would presume it would be chemical energy from burning fuel
What energy conversion happens in an fan?
fan converts electric energy into magnetic and further mechanical energy
How do you get energy from batteries?
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.
What is converted energy?
When steam is converted into energy, via steam pushing a turbine, turning a generator, making electricity.
How much energy is released by burning methane?
4450 kJ of energy would be released.
What peice of apparatus would you use to change chemical energy to electrical energy?
A battery uses a chemical action to produce direct current electrical energy.
What can be used to convert light energy to electrical energy?
Solar panels would work.
