The resolving power (ability to distinguish two objects close together) of a microscope is limited by diffraction of the waves used to illuminate the object.The shorter the wavelength of the wave the better is the resolving power, so microscope which use ultra violet light have a greater resolving power then those that use visible light.Electron microscopes use accelerated electron beams where the wavelength of the electrons can be 100,000 smaller than that of visible light thus increasing the resolving power of such a microscope by a great deal - enough to resolve molecules.
The reference to energy was because as the energy of photons or electrons increases the wavelength decreases.
