I’m confused. I did some research online, and learned that cpu’s can essentially double has a hotplate, because 99-100% of electricity consumed is turned into heat. how? doesn’t the cpu use energy to make calcuations and render things? I’m real confused.

CPU is a bunch of switches. When a switch is open, tiny current. Instant power, product of instant current and instant voltage, is low. Likewise when switch is closed voltage is small, again low instant power. The fun part is during the switching transition. That takes finite time, during which instant power spikes.
CPU has a bazillion switches, toggling a grunch per unit time. This makes the CPU toasty while it does it’s job flipping bits. Also why overclocking makes it hotter.
