The electricity supply of a certain U.S. state needs to be increased. The state is very cloudy and rainy from October to April. There are several large rivers, and there are almost no areas with high winds due to heavy forest cover. Several sources of underground heat are available. The state also has a surplus of organic waste.

  Name two renewable energy sources, and state and explain whether or not the state should use them based on the description above.

 Would hydropower energy and geothermal energy work as an answer?
