Beyond the Money: Mark Vargas put solar panels on his home in Santa Clara, Calif., but they get blocked by his neighbor's redwood trees. Earlier this year, Vargas asked prosecutors to press charges against his neighbors for shading the sun. But the couple next door insisted they should not have to chop down the trees to accommodate Vargas' energy demands because they planted the redwoods before he installed the solar panels in 2001.
