Tapping Wave and Tidal Ocean Power! Sounds like a plan to me!

2 posts / 0 new

In the most rigorous analyses undertaken to date, two recently released resource assessments show that waves and tidal currents off the nation's coasts contain enough energy to provide a significant portion our nation’s total annual electricity usage.

The United States uses about 4,000 terawatt hours (TWh) of electricity per year. The reports find that the nation’s waves and tides could potentially produce up to 1,420 TWh annually. The wave and tidal resource assessments, combined with preliminary results from ongoing DOE assessments of ocean current, ocean thermal, and hydropower opportunities, indicate that water power can potentially provide 15% of our nation’s electricity by 2030.

The West Coast, including Alaska and Hawaii, has especially high potential for wave energy development while significant opportunities also exist along the East Coast, which have strong tides that could be tapped to produce energy.

I think it's great that many ideas are on the table so to speak. Now if they would only get moving on them!! What do you know about wave energy projects? Any look promising to you?

Seems like this idea, like all the other "alternatives" have been on the table for decades. People have been trying different methods to efficiently turn wave power into electricity for over a century.

The reason why they are not widely done is the great cost involved relative to other ways of producing electricity.

The other way we're subsidizing Walmart...

Most of us know how taxpayers subsidize Walmart's low wages with billions of dollars in Medicaid, food stamps, and other financial assistance for workers. But, did you know that we're also subsidizing the retail giant by paying the cost of their environmental destruction.
