That took about 1,200 MW from the country's grid and brought electrical reserves to a dangerously low level.

The Energy Blog: Supergrid to Supply Europe with Wind Power - 0 views
-
The scheme would make the use of renewable energy, particularly wind power, so reliable and cheap that it would replace fossil fuels on an unprecedented scale, serving 1.1 billion people in 50 countries.
-
Czisch didn't comment on superconducting transmission, previous post, for some of the main lines, which are higher efficiency and more importantly can conduct up to 10 times the amount of power of today’s conventional copper cables of the same size.
-
The Independent reports that a proposed supergrid could supply Europe with carbon free electricity primarily from wind power. The 5,000-mile electrical grid, stretching from Siberia to Morocco and Egypt to Iceland, would slash Europe's CO2 emissions by a quarter, scientists say.
Electricity Cables To Be Buried (from York Press) - 0 views
-
SOME of North Yorkshire's finest views are to become even more picturesque, as work begins to bury unsightly electricity lines underground. Three areas of the North York Moors National Park have been selected for the burial scheme, with a further four lined up if funding allows. NEDL, the company responsible for maintaining the power network in our region, received a £5.5 million grant from electricity regulator Ofgem last year to carry out undergrounding work in seven protected areas.
Pros seem to outdo cons in new phone charger standard | CNET News.com - 0 views

The spaghettilike nightmare that forms many consumers' collection of phone chargers, headset connectors and data cables could be set to end after a major mobile-industry forum agreed to standardize on one type of connector.

The limited market penetration suggests that ignoring the differences and claiming universal compatibility will lead to consumer rejection. Politicians should develop the power of persuasion rather than the imposition of regulation.

In new dwellings domestic lighting suffers from inadequate installation. The formula is based upon the minimum number of lighting points arranged with the shortest cable runs. Consequently, lighting is often wrongly positioned and poorly controlled.
-
For some rooms, where there are fixed working positions such as kitchen and bathrooms, permanent lighting can be installed. For other rooms the lighting needs are determined by the layout of furnishings particular to a set of occupants. A more flexible arrangement is needed if the lighting is to both effective and efficient.

What's Green And Is Both New And Old? - Forbes.com - 0 views

While cable music channels urge their viewers to unplug their cellphone chargers and businesses strive to understand how big their carbon footprint is and how to reduce it, many authorities, city business districts, industrial sites and campuses are already turning to robust, tried and true solutions without waiting for magic-wand policies or revolutionary technologies. This explains why we're seeing renewed interest in district heating and cooling systems around the world.

Utilities Could Cash In On Climate Bill - Forbes.com - 0 views
-
Assume for the moment that Congress will not pass a carbon cap-and-trade scheme this year but that it does pass an energy bill that streamlines the siting of new transmission lines and requires utilities to get a certain minimum percentage of their electricity from clean sources. What opportunities would this open for AEP? On the efficiency side it would allow me to put capital to work on GridSmart [AEP's smart-grid initiative]. And instead of being a net buyer of renewable energy from third-party generators, I'd begin to be a net builder of renewables. It's the same issue as always: I'm satisfying a state or federal renewable requirement, and my customers' rates are going to go up anyways, so why shouldn't my shareholders get the benefit of our building that new generating capacity rather than buying the electricity on the market? If I'm just a net buyer in the market, I'm forced to buy solar power at 30 cents, and that goes through to my customers, and I don't think that's fair. I want to make sure my shareholders and my customers get a pretty good shake out of this.
Nobel laureate: Wind is not the future | Green Tech - CNET News - 0 views

Wind power is not the answer Steinberger now wants funding for a big pilot project. The idea is to link solar thermal power from Northern Africa to Europe via high-voltage undersea cables. The proposed 3- to 3.5-gigawatt power plant would cost an estimated $32 billion to build. Steinberger believes that 80 percent of Europe's energy needs could be met by solar thermal power plants in the Sahara by 2050.
Here is the 21st Century Storage and Transmission System for Wind Power - 1 views
-
1. Transmission Developers would provide electricity transmission in underwater cables (previous story this week), that can be lain in aqueducts, riverbeds and lakes, or down ocean coastlines – clearing the one big hindrance to the development of renewable energy, which is the new transmission needed, and the NIMBYism that succeeds in prevents that from being built, because these would be out of sight. 2. The other, Riverbank Power – an equally innovative breakthrough, would provide a complete solution to storing wind power (previous story) effectively making it dispatchable base-load power.

Le câble de démonstration, long de 30 mètres, comprenant les extrémités et l'enveloppe cryogénique associées, a fait la preuve de sa viabilité dans le laboratoire de Nexans à Hanovre.
ABB secures power line order in Brazil - 0 views
-
ABB will deliver five turnkey 34.5/69kV substations including 12 step-up power transformers rated at 33MVA, air and gas-insulated switchgear, medium-voltage reclosers, and distribution transformers. The company will also supply and install 60km of 69kV overhead transmission lines to connect a 290MW wind farm to the national electricity grid that is currently under construction in the northeastern state of Bahia. According to ABB, Brazil currently has around 600MW of wind power capacity, with another 450MW under construction.
2 New & Innovative Ocean Wave Energy Devices - 2 views
-
Ocean Treader is a floating device. It will be tied up 1 – 2 miles offshore in ocean wave systems. It will not pose any obstruction on the shoreline. The theory has been put to test in wave tank. Now the company is producing a full size machine for offshore testing. Wave Treader has grown out of our work with Ocean Treader. Wave Treader uses its Sponsons and Arms and are mounted on the base of a static offshore structure. That structure can be a Wind Turbine or Tidal Turbine. By sharing the high infrastructure costs with another device, such as the foundation costs, cabling costs, etc., the economics of both devices are enhanced and the energy yield for a given sea area greatly improved.

Financing and planning concerns also plague the project, with the level of state subsidies to the two main contracting firms - RTE (Réseau de transport électricité) and REE (Red Electrica de Espana) - still to be determined, and with questions remaining about the exact location of the future power cables.
-
Concerns include the potentially destructive impact of constructing electricity infrastructure in local communities and sensitive environments, and local civic organisations have mounted highly organised campaigns to contest the project, arguing that they have been given insufficient justification for the construction of the necessary power lines.
