Lighting is 2% of global energy, 6% of electricity, 25% of buildingsโ energy. LEDs are 2-20x more efficient than alternatives. Hence this 16-page report is our outlook for LEDs in the energy transition. We think LED market share doubles to c100% in the 2030s, to save energy, especially in solar-heavy grids. But demand is also rising due to โrebound effectsโ and use in digital devices. We have screened 20 mature and (mostly) profitable pure plays.
