There are so many sources of biogas, nuclear, hydrogen,... For me, solar energy is the best source of energy. Solar energy is solar panels that absorb the sun. Solar panels are put on the roof of houses to get energy from the sun. It will turn to electricity to supply electricity to the people. Solar energy has both advantages and disadvantages. Advantages, it's clean and safe. Solar energy is unlimited and plentiful. People use it for heating and cooking without any danger. Negative, although it's good, they are quite expensive. Installing a solar panel is difficult. Anyway, solar energy is very useful for our lives.
