What are the disadvantages to using solar and renewable energy?
The biggest disadvantage and the only truly significant one remains the cost. For example, solar energy technologies require a significant initial outlay. Still, in nearly all cases, this high initial cost is recovered through substantial fuel savings over the life of the product (15-30 years), and solar energy systems can last much longer than this. But in areas where there are no hydro wires, choosing solar is as obvious as the sun in the sky.
