A trio of U.S. senators this week introduced a bill to spur solar manufacturing jobs in the United States.

Through additional tax credits, the legislation aims to encourage more U.S. companies to make solar equipment, creating jobs and building up the country’s clean energy economy.

Many — from politicians and environmentalists to investors –  have pinned great hopes on green jobs. Clean energy could create 850,000 manufacturing jobs in the United States, according to recent research Reuters reported this week.

The latest proposal could create 315,000 U.S. jobs along, according to Solar Energy Industries Association, which is pushing for the bill.

But would the extra tax incentives be enough to keep solar power companies producing in the United States?
