  • KEMA, in partnership with the civil engineering firm Bureau Lievense and technology illustrators Rudolph and Robert Das, has developed an "Energy Island" concept to store power generated from an offshore wind farm. The concept design is the initial result of an on-going feasibility study being conducted for Dutch energy companies.

  • A study conducted by Stanford University confirmed that interconnected multiple wind farms can be used to provide baseload electric power. Interconnecting wind farms with a transmission grid reduces the power swings caused by wind variability and makes a significant portion of it just as consistent a power source as a coal power plant. "This study implies that, if interconnected wind is used on a large scale, a third or more of its energy can be used for reliable electric power, and the remaining intermittent portion can be used for transportation, allowing wind to solve energy, climate and air pollution problems simultaneously," said Archer, the study's lead author and a consulting assistant professor in Stanford's Department of Civil and Environmental Engineering.

  • Technological advancements in wind energy efficiency have generally come incrementally and usually made via a process of increasingly large wind turbine blades. Put simply, the model has been: longer blades = more output per turbine.

  • Construction will start next week on the £42 million Wave Hub marine energy project in South West England.The Wave Hub, which will be located 10 miles off the north Cornwall coast, will serve as a test bed for wave energy devices by providing an electrical connection from the seabed at a depth of around 50 m to the national grid.Initially, the Wave Hub will have four berths for wave energy devices up to a maximum capacity of 20 MW, but has the potential to scale up to 50 MW in the future.Ocean Power Technologies has signed up to take the first berth when it becomes available to test the performance of its PowerBuoy wave energy converter.The first devices are expected to be deployed in 2011, once the cabling and connectors have been constructed. Starting on Monday, civil engineers will drill ducts from Cornwall coast at Hayle to connect to the subsea cable and a new electricity substation on the site of a former nearby power station.

    This Wired article summarizes and links to a poster for the American Geophysical Union meetings (pdf) from Elaine Hart, a graduate student in civil and environmental engineering at Stanford. Her power flow simulation suggests that the existing transmission network in California can accommodate up to 70% of renewables in the portfolio on a hot summer day. The number of overloaded lines in the simulation rises from 11 to 31, which is not that large an increase given that there are almost 5,000 transmission lines in California. Still, this kind of work can be really useful to help target transmission investment. The Wired article also has some good links for further reading. I look forward to seeing more of this research!

canada efficiency lighting policy

shared by Hans De Keulenaer on 02 Apr 08 - Cached
  • Compact fluorescent light bulbs are much more energy efficient than incandescent lighting. No arguments there. But is it wise to outright ban the old Edison light bulb in Ontario? Across Canada?A year ago this writer would have had one answer: Definitely. But the answer, it turns out, shouldn't be so clear cut.At least that's the conclusion of a recent paper by Michael Ivanco, a senior scientist at Atomic Energy of Canada Ltd., and professor Bryan Karney (along with graduate student Kevin Waher) from the department of civil engineering at the University of Toronto.The three have authored a study called "To Switch or Not to Switch: A Critical Analysis of Canada's Ban on Incandescent Light Bulbs," and you may be surprised by the findings.
