because muscles generate heat when they work.
When we exercise, our muscles generate heat. Perspiring stops us overheating. When sweat evaporates off the skin, it takes away excess heat, which cools us down.
When you excercise you generate excess heat and your body temperature rises. Blood vessels dialate in the skin, warm blood flows closer to the body surface, and you loose heat this exceplifies what

Muscles generate heat through contraction which helps to regulate body temperature. When the body is cold, muscles shiver to produce heat, while during exercise, muscles generate heat to maintain body temperature. Additionally, increased blood flow to muscles during activity helps to dissipate excess heat and maintain a stable body temperature.

Two ways to generate heat energy are burning fossil fuels, such as coal or natural gas, to produce heat through combustion, and using electrical resistance heating, where electricity is passed through a resistive element to generate heat.

Hydropower does not use heat to generate electricity. Instead, it harnesses the energy from moving water, such as rivers or waterfalls, to generate power through turbines.
Muscle activity produces heat so that exercise creates a heat surplus that can actually be fatal. In response to exercise the body has to redirect blood flow to the skin to facilitate heat transfer out of the body.
Solar panels don't generate heat; they convert the energy of sunlight into electrical energy, which I suppose could be used to generate heat.
They do not generate enough heat to burn a book if cliped on and the bulb not close.
