The chemical energy in the food will be converted into mechanical energy, mainly kinetic energy; this will quickly turn into heat.
Chemical energy in you body is converted, in you muscles, to mechanical energy which enables you to flip or press the switch.
The mechanical energy of wind pushes on the blades, turning them (still mechanical energy) turning blades turn the generator (still mechanical) The generator changes mechanical energy to electrical energy.

Muscles store chemical energy from the food your body broke down, then your muscle turn those chemical energy to mechanical energy when they contract.

nutrition
food is oxidized meaning it reacts with oxygen and CO2, H2O and energy in the form ATP is produced
The mechanical energy of wind pushes on the blades, turning them (still mechanical energy) turning blades turn the generator (still mechanical) The generator changes mechanical energy to electrical energy.
Mechanical energy into electrical energy
it takes your body longer to turn your food into energy
Let falling/running water turn a water wheel, hydroenergy to mechanical energy.
mechanical
As you exercise your body uses stored fuel and turn it into energy to power mechanical movement. In this process, energy in the form of heat is released in to the surroundings. Therefore this is an exothermic process.
