Advantages of renewable energy: A study

The demand for energy to power our homes, businesses, and communities grows along with the global population. Maintaining a sustainable energy level and preventing climate change need innovation and expansion of renewable energy sources. The International Energy Agency (IEA) predicts that by 2024, 30 percent of the world's electricity would come from renewable sources, up from the current 26 percent share. The IEA's executive director, Fatih Birol, stated that "renewable energy is at a critical juncture right now."
