Waves used in power delivery resemble the former and waves used in information delivery resemble the latter. Sources: Cdang CC BY-SA 4.0; Ivan Akira CC BY-SA 3.0.
LEFT: Inefficient radiative energy transfer as used in radio signal transfer: energy is passed to energy carriers (photons), a small fraction of which get absorbed by the receiver. RIGHT: Efficient nonradiative energy transfer as used in wireless phone charging: energy is passed directly to the receiver via force carriers (virtual photons). Sources: Trixt CC BY-SA 3.0.
Basic steps of the photosynthesis process: a photon is absorbed by a molecule. The energy then transfers rapidly across molecules to the reaction center where it is utilized electrically and later chemically. Source: Taiz & Zeiger 2010.

Recent proposals for enhancing the efficiency of solar cells via resonant excitation transfer combined with energy downconversion (based on Einzinger et al. 2019).
LEFT: Proposed scheme for an aneutronic nuclear thin-film application: a hydrogen-hydrogen fusion reaction (1) forms an excited state (2) whose energy gets transferred — before conventional decay — to matching receiver nuclei (3); receiver nuclei decay into charged particles (4); an alphavoltaic semiconductor generates electricity from the charged particles. RIGHT: Recent miniaturization efforts for nuclear devices: a neutron generator based on hydrogen-hydrogen fusion reactions.
