Energy is considered green if it is renewable and efficient. Energy from solar, wind, hydrogen, or other sources are renewable, and thus considered energy efficient and green. Another thing to keep in mind is how much energy it costs to convert the energy for use. If it is a renewable energy source, but uses so much evergy in the conversion, then it is not going to be as green.
