This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

It's been an incredible year in green news, and coverage on the environment seems to increase every week. Below, you will find links from the last year that I think are important. Unfortunately, tons of good stories didn't make the cut because the links were broken and I couldn't find an adequate replacement. Regardless, 2007 has been a great year, don't you think? Collectively, we're taking big steps to respect the environment. Republicans, Democrats, businesses, individuals, etc. Everyone wants to do their part. And even if you don't click all, er, 151 links below, scan the titles as a reminder of what has been accomplished. Let's keep the momentum in 2008.

Prysmian Group, the industry leading cable and systems provider, won a contract worth a record-breaking €800M for the development of a high voltage DC submarine power transmission link between Scotland and England. The project will involve the use of at least 400km of a new Prysmian-developed cable product called Mass Impregnated PPL cables, which utilises new material technology to operate with a record longhaul wiring voltage rating of 600kV. This means that energy losses will be kept to a minimum, resulting in a low CO2 footprint for the supply of Scotland-sourced renewable energy for England and vice-versa (the link will be bidirectional). Commissioning is expected in late 2015.

UK telecoms provider BT is to invest £1.5 billion ($3 billion) to roll out superfast broadband to up to 10 million UK homes by 2012. The system will enable services such as video conferencing, video on demand, and other high bandwidth activities. The programme is Britain's largest ever investment in superfast broadband, which will deliver speeds of up to 100 megabits per second. The fibre will be linked to a cabinet in the street and in some cases - such as the Olympic village for the 2012 Games - directly to the premises. Homes linked to a fibre-to-the-cabinet network will receive initial speeds of up to 40 Mbps, due to the copper cable that connects the house to the cabinet. However, BT expects this to increase to 60 Mbps with new technologies. Those on a fibre-to-the-premises network will see speeds of up to 100 Mbps.

I believe this assumption is basically incorrect. The current financial crisis is a direct result of peak oil. There may be oscillations in the economic situation, but generally, we can't expect things to get much better. In fact, there is a very distinct possibility that things may get very much worse in the next few years. In this post, I will put together some of the pieces I see. This post is based on a presentation, so includes more than the usual amount of graphics. The post repeats many things I have said before, but I wanted to bring more of the pieces together into more of an overview article. This is a link to a PDF version of the presentation. This is a link to the Powerpoint version.

"The new link will be particularly significant to the development of a European offshore grid able to integrate increasing levels of offshore wind and marine power in coming decades."

"Developed by Prysmian's R&D Headquarters in Italy, P-Laser technology is eco-sustainable. The HPTE insulating system of P-Laser cables uses thermoplastic materials unlike traditional XLPE cables with cross-linked polyethylene insulation. The metal used for the conductor and the outer cable screens under the protective sheath is also recyclable, making the cable 100% eco-friendly. From the efficiency point of view, P-Laser technology allows grid operators to work at temperatures above the typical 90°C as usual with XLPE traditional technology. This higher thermal performance allows them to increase the power transmission for the same conductor section, or a longer cable life at the same temperature, but above all it allows higher capability. This is particularly important in the event of emergencies, grid congestion and "N-1" conditions (disconnection because of malfunction or maintenance of an adjacent line)."

Japan's domestic shipments of residential air conditioners rose 12 percent in March from a year earlier to 678,736 units, the Japan Refrigeration and Air Conditioning Industry Association said.

But the humble copper cabling linking most households to the internet looks set to remain a feature of our national IT infrastructure for some time yet.

Dr. Webber explains the intricate and increasingly vital links between energy and water, both in the United States, and the world.

Switzerland-based power and automation technology group, ABB Ltd., won a contract tendered by TenneT, the Dutch-German transmission grid operator, to connect North Sea wind farms to the German mainland grid. The order is worth US$1.0B and ABB expect to use over 135km of 320kV submarine cable in the designed transmission system. The project is expected to be operational in 2015 and follows two other offshore wind connection orders for ABB in Germany; the 800MW Dolwin1 link awarded last year and previously, the BorWin1 project. The Dolwin1 link is expected to be completed in 2013 and will involve the use of 150km of 320kV copper submarine cable.
