While wave power often seems like the poor cousin of the renewable energy world, and frankly doesn't have the practical potential of wind or solar power, tapping the power of the sea does have its place and this next one is worth a bit of hand clapping: One of Ocean Power Technologies' PowerBuoys can claim to be the first wave power device to deliver electricity to the US grid.

The U.S. electric grid is a complex network of independently owned and operated power plants and transmission lines. Aging infrastructure, combined with a rise in domestic electricity consumption, has forced experts to critically examine the status and health of the nation's electrical systems.

The variability of renewable energy sources such as wind, often cited as the sector’s Achilles’ heel, does not have to be a problem, according to a new report from the UK's National Grid.

Tom Raftery no es un nombre demasiado conocido, aunque no para de dar conferencias por diversas partes del mundo, desde Berlín hasta Nueva York.

Su última parada ha sido Sevilla para debatir en el EBE (Evento Blog España) de un concepto relativamente nuevo, el GRID 2.0 (red de segunda generación), una idea nada fácil de definir, pero que podría traducirse como la redistribución de la energía eléctrica gracias a la tecnología, de un modo similar al que utiliza Internet para distribuir el conocimiento. Una especie de Electranet.

Business Week is reporting that ”...13 days since Hurricane Ike ripped through Texas, and nearly one-quarter of the residents of the fourth-largest U.S. city still don’t have electricity.”

Is the problem electricity production?
No. The power plants are fine.

The problem is the wires. The grid itself
The network is too vast to repair quickly in the fall out of Hurricane Ike.

The problem is storage.
We have no viable way of storing vast amounts of electricity at the local level.

The solution? Making energy storage a priority and create systems that support a local ‘Electron Reserve’.

The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.

The grid today, according to experts, is a system conceived 100 years ago to let utilities prop each other up, reducing blackouts and sharing power in small regions. It resembles a network of streets, avenues and country roads.

“We need an interstate transmission superhighway system,” said Suedeen G. Kelly, a member of the Federal Energy Regulatory Commission.
