Three types? I can think of more than that. But I suppose if we group some together: there is mechanical energy, solar energy, wind energy, hydro energy. Thermal energy in a power station is transformed into mechanical energy so is covered by that. But then both wind energy and hydro energy convert to mechanical before the electricity is produced.
So really at a fundamental level there seems only mechanical and solar. Mechanical would include fossil fuels, (coal, oil, natural gas,), nuclear, wind, incinerators, hydro, geothermal, and biomass, which all drive a mechanical device to produce the electricity. Solar produces electricity directly from photovoltaic cells so that is not mechanical.
it transforms it to and energy called El Nino
A generator transforms mechanical energy into electrical energy.
A geothermal one
That's called a speaker.
Every conventional electrical generator does that.
Alternator
A loudspeaker

electrical energy transforms into machenical energy.
When you turn on a toaster, the electrical energy transforms into thermal energy to toast your bread. =]

A light bulb in an electrical circuit transforms electrical energy into light energy and thermal energy (heat).
