If you think science is cool, then energy would have to be cool as well, especially how it is involved with and in science.

from warm to cool, warmth is energy, coolness is the absence of energy.

A fridge typically uses electrical energy to power its compressor and other components that cool the interior. This electrical energy is converted into mechanical energy to circulate refrigerant and remove heat from the interior, keeping the contents cool.
Using a fan or an air conditioner to convert electrical energy into mechanical energy for air circulation and cooling can help you stay cool on a hot day.
Buildings take energy to heat them and cool them. No insulation means the heat or cool escapes to the atmosphere and wastes/costs energy (and money).

A heat pump is a device that transfers thermal energy from a cool region to a warm one. It does this by using a refrigeration cycle to extract heat from the cool source and release it into the warm sink.
