Solar Impulse Efficient Solution
3,023 projects on Keys for Tomorrow carry the Solar Impulse Efficient Solution label, awarded by the Solar Impulse Foundation to technologies and solutions that are both environmentally beneficial and economically profitable, based on an independent expert evaluation against defined sustainability and viability criteria.
This label is specifically about proving that a clean technology is commercially viable, not just environmentally sound, which is why the Solar Impulse Foundation is also one of Keys for Tomorrow’s core data sources.
