Solar energy is also used to power military drones, which can be remarkably similar in design to Solar Impulse 2. The next step will be to harness the technical gains of Solar Impulse to improve power-to-weight efficiency in related fields. PARIS - In its round-the-world tour, the plane Solar Impulse 2 has become a showcase for Sun-powered technology, featuring innovations which could have a bright commercial future. Even so, solar energy only constitutes less than one percent of the world's output, dominated by fossil fuels of oil, coal and gas. Recent progress in electricity storage mean it is now feasible to have solar energy plants a long way from traditional power grids.
