There are so many examples for that in different areas, like organic germanium compounds experiment carried out in our lab recently.

Solar energy is energy that comes from the sun and is captured by solar cells. These cells transform the energy of photons of light into electrical energy. One mechanism is the energization of electrons, here the energy of the photons is transferred to the electrons, which can already be considered electric energy.
As for the hydroelectric energy, here the waterfalls or rivers flow driving a turbine, which will transform the movement into usable electric energy as it rotates.
It is important for scientists to remain open minded about information that they come across in their experiments, so that they do not become biased about the result. it can always happen that the results that come out are contrary to what the scientist expected. It is important to openly accept that the scientists prediction was wrong.
