Solar energy seems to be the most popular clean energy technology right now. This is reasonable because it is free energy that we can take advantage of while not contributing to greenhouse gas emission levels. Although wind energy is also free, it is more difficult to extract. Solar energy also has its drawbacks since it the Sun only shines during the day whereas wind acts throughout the day. However, solar energy is preferred because it generates three times the energy it takes to manufacture. Plus, solar energy technology is improving more than wind energy is with mirrors to increase yield, photovoltaic technology, and solar panels that adjust to the position of the incoming sunlight.
