Electricity
Water
The steam engine helped to power the Industrial Revolution. Before steam power, most factories and mills were powered by water, wind, horse, or man. Water was a good source of power, but factories had to be located near a river.
You may find it helpful to use Ohm's law and the definition of electrical power.
After about 1890, yes. The use of electricity for lights was far safer than the previous alternative of gas lamps.
Steam power is used today as a form of power for many things. Some of these include powering factories and mills.

At first water power was the primary power source. Factories were built on the banks of rivers, and huge water wheels driven by the flow of the river would power the factory. Then the invention of the steam engine made it possible to build factories almost anywhere, and steam engines replaced water wheels as the primary power source in factories.
Factories could be built away from rivers using this alternative source of power.
You would use a standby generator as a back up electricity source when there are outages of electric power. Business such as factories and also offices would have a standby generator in place.
A water-powered factory did not create pollution and could only operate near water, but a steam-powered factory did create pollution and could operate anywhere on land
Mostly Electricity from Grid
To power anything in your house, factories, farms that use electrical current.
Yes, MacBooks use lithium-ion batteries as their power source.
Steam energy allowed factories to move away from rivers.
