Photovoltaics (PV), more commonly known as solar electricity, is a highly debated renewable energy source. Even though it's estimated that a single patch of land (100 square miles or 259 square kilometers) in a location with a reliable amount of sunshine could generate enough PV to power the entire U.S., many people are slow to accept the viability of solar power. The arguments against the use of PV include its low-voltage output and narrow range of practical applications. But perhaps it's more an issue of narrow-minded thinking; solar power technology continues to develop and its use is increasing.
