    Since 2000, the amount of clean energy generated annually in the United States has increased by almost 63 percent, while carbon dioxide (CO2) emissions have decreased by almost 10 percent. This trend suggests a connection between the increased use of renewable energy and reduced CO2 emissions, which is good news for the environment.
