CONCORD, N.H. (AP) — There's plenty of raw electricity sloshing around in Quebec's rivers and reservoirs, offering promise for U.S. northeasterners who pay the nation's highest power costs. But getting those electrons to smartphones and air conditioners in Boston, Hartford and New York City is another matter entirely. Critics of proposals to import relatively clean hydropower from Quebec worry that transmission lines will despoil the natural beauty of places like New Hampshire's White Mountains.
