Modern home computers are usually very efficient and use little power but it would depend on the make, model and monitor.
That varies from computer to computer depending on how much power it needs. Some computers even have several different fuses.
Almost all computers today use MS windows.
Yes in the modern world they use computers.
Since the second generation transistorized computers there has been no use of vacuum tubes in computers except for one thing, CRT displays. In the last few years even that has been eliminated by modern flat panel LCD & LED displays, which are much lighter and less power hungry than CRT displays were.

The Allied Forces military used the computers in its first elemental form. In time use of the computers extended from military use to government use and commercial use. But those computers could be as big as our living rooms and still not have as much computer power as a calculator of today.
The vast majority of the modern world.
Computers of the 1950s were very different than modern computers. They took up so much space that it often required several rooms. They also had huge power requirements and generated large amounts of heat. Computers of the 1950s were also highly unreliable, often requiring many hours of troubleshooting and programming to accomplish a few minutes of productive work. Also, computers of that era were not useful for much more than mathematical calculations, there being no internet to surf or games to play, most homes had no need or use for a computer.
Modern computers typically do not use a coprocessor. Floating-point capabilities are built into the CPU.
Many modern feed mills increasingly rely on computer technology
