The problem is electricity prices are too low

Low prices for electricity is just one of the problems facing renewable power developers in the USA.

The 'problem' could be stalling plans for alternative energy projects like developing hydrokinetics - energy from water sources like the Mississippi where instead of using dams, energy would be harnessed from sunken and surface based turbines, making use of the flow of river water.

Experts reckon new advances in generators, capable of running on variable speeds (due to the flow of water), could hold the key (source AP)

Although the 'wave' technology is still in its infancy, hence little data on exactly how much energy such installations could produce reliably, installation projects are underway.

BP & Gulf of Mexico Oil Spill - The Day we've been fearing is here

No pithy illustrations, no witty comments, just a very sad and sombre day when I clicked on a tweet by @greenforyou which took me to the most vivid pictures of oil finally coming ashore on the coast of Louisiana as it washes up on the shores of the Mississippi Delta and marshlands.

Home of course to not just outstanding wildlife, but people too - their homes, businesses and livelihoods.

Very sad.
