Fusion happens at the Sun's core. Hydrogen atoms are fused together into Helium, a process that creates a lot of heat and light... energy. This energy is transferred through space as radiation. Infrared, visible light, ultraviolet... the whole electromagnetic spectrum travels to us through the vacuum of space... when it strikes the Earth, the Earth reflects and absorbs certain percentages of certain wavelengths, giving us light, and conduction happens, giving us heat.
