PBS News Weekend

On Saturday, NewsHour Weekend explores the popularity of solar energy in Hawaii, where residents pay the highest electricity costs in the country. In the tropical climate where federal and state tax credits make going solar a no-brainer, many homeowners have chosen to install rooftop panels. But in some parts of the state, the local utility company has slowed down approvals of new solar systems, saying that abundant users may threaten the safety and reliability of the power grid. And as the popularity of using rooftop solar energy permeates throughout the rest of the country, many Americans could soon enter the same gridlock. NewsHour Special Correspondent Mike Taibbi reports from Oahu, Hawaii.
