Renewable energy has come a long way in a relatively short time. But there are still many questions about the cost effectiveness and feasibility of investing in renewable energy sources such as solar or wind power, especially on an individual level.
Solar power has led the renewable energy pack for years. In terms of long-term reliability, solar power generation has the best odds of meeting global energy needs. However, as far as current global production rates go, wind-generated power often runs neck and neck with its sunny counterpart.
