Renewable energy is increasingly important for the future according to businessman Michael Anthony Sawyer. Sawyer notes that shifts from primary to alternative energy sources have occurred before due to depletion, such as from wood to coal to oil. Today, fears of depletion and fluctuating oil prices are increasing demand for renewable alternatives like wind and solar. While these currently provide a small portion of U.S. energy, government incentives and rising oil costs are pushing more toward renewable sources. Sawyer believes renewable energy is the future for many countries as the trend continues to rise in coming years.
