Through leapfrogging, developing countries can accelerate development by adopting more advanced technologies that skip inferior or polluting options used by industrialized countries. Leapfrogging allows developing nations to avoid harmful environmental stages of development and not repeat the fossil fuel-based energy mistakes of highly industrialized countries. An example is how some developing countries have implemented solar energy technologies instead of building energy infrastructures reliant on fossil fuels, essentially "jumping" straight into the Solar Age.
