The US Congress last week extended some $17 billion in tax incentives for wind, solar and other renewable energies as part of the rescue package for Wall Street banks.

The tax credits had been set to expire at the end of this year, and legislation extending them had languished for months over disputes on how to pay for them (see _Nature_ 455, 572–573; 2008). A resolution seemed unlikely until Senate leaders wrapped it into the bailout package.

The legislation extends for one year a tax credit for producing wind power that is currently valued at 2 cents per kilowatt hour. The solar industry came out particularly well with an eight-year extension of its 30% investment tax credit.
