What are the advantages and disadvantages of solar and wind energy?

Answer 1

Though they are both sustainable sources of energy, both of these forms of energy production are extremely expensive to create. Because solar energy is a relatively new form of energy, the materials and production of the final product are both complicated and expensive to create. Wind energy, though not new, is still quite expensive to make and maintain. The reason is because the turbines you see driving along the road are massive structures and have many components to clean, replace, and maintain throughout said turbines' life. So, though at face value, these are cheap, easy forms of energy, they actually are rather expensive ways to harvest energy. But, they are sustainable, and as long as the wind still blows and the sun shines, these forms of energy will always be viable.
