Electron as one component of the solar wind, can influence the solar wind through several mechanisms. The electrons in the solar wind usually exhibit two features in the non-thermal equilibrium distribution: temperature anisotropy and electron beam. Such a non-thermal equilibrium distribution can excite electron instabilities and generate plasma waves through wave-particle interaction. The generated waves can regulate solar wind particle distribution in turn, resulting the heating of background particles in the solar wind. Thus electron kinetic instabilities play an important role in the evolution of solar wind. This manuscript will introduce the electron kinetic instabilities in the solar wind. Based on the plasma kinetic theory, we will discuss the instabilities which emerge during the solar wind propagating process, especially the electron acoustic heat flux instability and lower hybrid heat flux instability in the solar atmosphere and the inner heliosphere. In addition, we analyze wave-particle interaction mechanism of these instabilities, in order to make a profound study of the evolution of the electron distribution function in the solar wind propagating process.
