In her new book, ‘The Grid,’ Gretchen Bakke argues that the under-funded power grid is incapable of taking the U.S. into a new energy future. Bakke says, “We can make a lot more electricity than we can use, and we can make more electricity than the grid can carry, but the grid is the weakest link.” Also, classical music critic Lloyd Schwartz reviews ‘Let Me Tell You,’ by Danish composer Hans Abrahamsen in collaboration with soprano and conductor Barbara Hannigan.
