San Francisco Mayor Gavin Newsom: Power America With Ocean Energy

We have a choice. Invest in safe, renewable forms of ocean energy -- including wind, wave, tidal and current power -- that will help secure our future prosperity, create thousands of new jobs and reduce our dependence on foreign oil. Alternatively, we can continue to give tax breaks to oil companies that pollute our oceans and keep us locked in a carbon age.

Faced with a choice between a downward spiral of environmental degradation and increased reliance on a finite resource or investing in safe, renewable energy that can power our country and save our planet, the choice should be clear.

Tidal Power in U.K. Opposed by Surfers, Environmentalists | Miller-McCune Online Magazine

Many environmentalists oppose a 'green' idea for tidal power in the U.K. So do British surfers.

British surfers, unsurprisingly, are against a barrage, even though it will be different from the Hoover Dam. "The pointless and emotive sacrifice of a fully functioning river system to the gods of climate change is a misguided indulgent 'green' luxury," says Stu Ballard, a bore surfer who runs a nonprofit called Save Our Severn. He worries that a rush by the government to build the barrage, driven by European Union carbon-reduction goals and a few special interests, will lead Great Britain down a byway explored by Canada decades ago. "For the Canadians," says Simon Haslett, a professor at the University of Wales, Newport, "the idea of a barrage is now history and doesn't even get raised as an option during tidal power debates. It's so old that they are amazed the U.K. is even considering it."

Of course, the British public doesn't have much use for any "save the bore" movement based on a surfing wave, but most environmental groups agree with the surfers, and surfers have mounted the most interesting resistance.
