Next, solar power is another technology that is used to create energy from sunlight. There have been advances in recent years with solar panels, such as the discovery that nanoparticles in an organic dye can convert sunlight into electricity, according to researchers at the Fraunhofer Institute in Germany (Hunt 3). The electricity-generating film is placed between two glass panes, and because of the small size of the nanoparticles, the resulting solar modules are semitransparent (Hunt 3). In addition, some states are making efforts to encourage solar power in private and commercial use. Duke Energy Carolinas is proposing a $100 million
