The year is 2050, and the ocean level has risen. More than half of the North Pole has melted, and most of the coral reefs in the oceans have perished because of the rising temperatures in the water. Hurricanes have become so severe that millions of homes on the coasts have been evacuated. How could the world have come to this horrible fate? Can we improve alternative energy to help us for the future?
Alternative energy: a concept that could revolutionize the world. Researchers are improving the technology to harness as much power as possible — especially in solar cells. Researchers at Iowa State University in Ames, Iowa, created a solar cell that captures more light and produces more power. A major accomplishment in the field of alternative energy, the new and improved solar cells capture 20 percent more light than the average solar cell. Iowa researcher Sumit Chaudhary says that the solar cell not only has a 20 percent improvement over traditional solar cells, but it also captures 100 percent more light near the red/infrared light spectrum.
Instead of the oceans rising and the Arctic ice cap melting, we could make a decision to focus more on renewable energy sources and change our fate before it's too late. Renewable energy is the only smart choice for the future, and we should realize that before it is too late.
