New method of decommissioning wind turbine concrete bases with water jets

With this new removal technique, the top metre of the base is removed. A backhoe digs a hole around the concrete base once the tower is removed. Then an automated high-pressure water jet is set up to fire a jet of water up close and rotate around the concrete base, directing the thin, high-pressure stream of water, cutting deeply into the base, slicing both the concrete and the rebar inside. The water jet rotates around the concrete pillar firing the high-pressure water jet until it is done. The top metre of the top of the concrete pillar is then lifted off.

Stay granted: Work at Ostrander Point is stopped until an appeal decision is rendered

In a surprising twist of the plot, the Ontario Court of Appeal granted a stay last week, barring a developer from proceeding with construction of an industrial wind turbine project at Ostrander Point in North Marysburgh. The court went further—seemingly pushing open a wide doorway through which the Prince Edward County Field Naturalists will pursue an appeal to a Divisional Court decision in February that restored the Renewable Energy Approval (REA) permit to a unit of Gilead Power Corporation.

Wind-turbine plan envisions switch to nuclear

Tiny nuclear reactors originally designed to power mini-submarines could eventually replace wind power in a local firm's plans for storing energy as compressed gas in pipelines across North America. Dave McConnell, president and CEO of Niskubased Lancaster Wind Systems, said Tuesday the additional details of his project can now be discussed after provisional patent protection was gained in the U.S. late last week.

Alberta wind farm worries residents

Darrel and Jean Gogel's Trochu acreage is a piece of calm in a hectic world--where Darrel can retreat after working days away as a truck driver, and Jean can unwind from her job as a hospital housekeeper. That could change, the couple says, if a plan for a 54-turbine wind farm near their house goes ahead.

Power demand requires new lines: Hydro One

While the mention of energy sparks visions of the Alberta oil fields and massive hydro projects at Niagara Falls and James Bay, a new energy powerhouse is emerging closer to home. Ramped-up production at the Bruce nuclear power facility and the increasing presence of wind energy are putting Southwestern Ontario in the spotlight as a provider of electricity. ...

More wind by 2012

As electricity created by wind generation increases, there has to be a way for that electricity to be connected to the provincial system and transmitted to users. The Alberta Electric System Operator (AESO) provides that role and explained what it is currently doing to the council of the Municipal District of Willow Creek at its meeting on Jan. 9. Ata Rehman and Matt Gray of the AESO appeared as a delegation and described the current situation. The AESO plans the transmission system, arranges access for load and generation, and directs the day-to-day operation of the system. Transmission planning is a two-step process. First, the AESO identifies the need for transmission development and submits a need identification document to the Alberta Utilities Commission which will include a recommendation for transmission reinforcement in the area.

Gale-force controversy

The debate over Mag-Wind is raging on green energy Internet forums, too. Critics argue with supporters about whether the unproven technology will produce power as advertised. A few would-be customers in the U.S. also complained about an unauthorized dealer in the Midwest, now under investigation by the FBI, who allegedly took deposits for non-existent Mag-Wind turbines. The gale-force controversy has surprised Mag-Wind founder Rowan. The delays and problems are real, he admitted - but so is the technology. Back in 2005, when Rowan and co-inventor Thomas Priest-Brown unveiled their prototype in Thorold, they hoped to be producing and delivering commercial units by the end of 2006. ...Well-known wind advocate Paul Gipe has called the company's power claims for the turbine "outlandish" on his website, ...Gipe's best advice: make sure you understand what you're buying. "If you're going to spend $10,000, or $50,000 or $100,000 on a wind turbine, do your homework," he said.

Wind power project gaining strength

Lacombe County doesn’t exactly stand out as a windy destination. However one wind power group sees it as a place of potential. Greengate Power Corp. is looking at establishing wind power turbines on two sites near Lacombe - one to the north bordering Ponoka County – and one five kilometres east of town, dubbed the Chigwell Project. “Traditionally wind hasn’t been looked at here in this area as a source of power,” said Dan Balaban, Greengate founder, president and chief executive.

A mountain of questions; Ski hill operator, residents raise concerns about impact wind farm of Wentworth area

A proposed wind farm project for Higgins Mountain is causing some concern for the operators of Ski Wentworth and others in the Wentworth Valley-Folly Lake area. "I want to make it clear that we are in favour of renewable energy and all of the benefits that come with it, but we do have some concerns about the proposal that will see 400-foot (120-metre) turbines being erected right across the valley from the ski hill," Ski Wentworth spokeswoman Leslie Wilson said Monday. Ottawa-based 3G Energy Corp. proposes to build 66 turbines along a seven-kilometre stretch of the Cobequid Mountains. They would be on a ridge on the opposite side of the valley from the ski hill. The project is among the largest ever proposed for Nova Scotia.

Wind power gaining momentum on Labrador's coast; Researching for alternatives

Roxanne Notley, Executive Director of the Aurora Development Corporation feels no decision has been made on wind energy development on the south coast. "We are not totally convinced about wind energy. The reason is because we just don't have enough information to validate our argument. So we used a proactive approach to determine if wind diesel would provide enough wind energy for now and in the future." ..."I did hear some comments from people. Most thought, 'oh my goodness, we are not getting wind power are we.' They are very worried, and scared that this is something that is going to be our alternative," noted Mrs. Notley. The problem with wind and diesel powered generation is that it is not reliable for taking on huge energy loads.

Look before you leap; Dairy farmer Schmidt says he didn't do enough research into wind energy

Dairy farmer Michael Schmidt had some advice for anyone thinking of getting into wind energy production for private use. ...Making sure the spot planned for the wind turbine has enough wind to support the investment throughout the year is the key ingredient. Schmidt sank $200,000 into an 80-kilowatt wind generator on his Durham-area farm without first having set up a test tower to assess wind speed and atmospheric conditions on his farm for a year. "Wind volume can vary 30 to 40 per cent a year," said Schmidt, who admits he rushed into a decision before doing enough research.

Saving sunshine could soon be the law

The question is no longer "Who has seen the wind?" but "Who owns the wind?" In the developing world of renewable energy, can neighbouring wind farms steal from each other? What if you put solar panels on your roof and your neighbour plants a tree that blocks them from the sun? Do you have a right to solar access? These aren't just philosophical questions, but real-life challenges that are already lining lawyers' pockets in Canada and Europe.

Money Blowing in the Wind

Wind power is not the answer to global warming. Do we have alternatives? We certainly do have alternatives to windmills but they would disrupt the lifestyle of electors and consumers. In Paris, an article in the September 2007 issue of the medical journal, The Lancet, shows with supporting calculations that it would be better to minimize human consumption of meat, for 80% of agriculturally produced methane comes from farm animals. Wind turbines won't even alter the greenhouse gas equation but by a mere .03%, as mentioned above. The way to reduce CO2 emissions and other greenhouse gases is to use less energy. Governments must massively invest in energy conservation measures rather than in these wind machines. According to another research, if every English household switched for one single low energy light bulb, a fossil fuel-burning electrical plant could be shut down! Wind power would only be interesting if energy produced can be stored. It has been proposed to fill reservoirs of large hydroelectric dams, for example. An Australian method has just offered in September 2007 to store electricity in liquid accumulators. Quebec would thus be able to utilize wind energy because the major part of our electricity comes from hydroelectric dams, which is not the case for Ontario or New York where, as almost everywhere else in the world, wind power must be backed up by carbon-based generating stations.

'Weak' grid holding back wind energy: report

Newfoundland and Labrador has great potential for wind energy, but is hampered by an "isolated and relatively weak" power grid, a confidential report says. The report, obtained by CBC News, says the island's electrical grid will limit the size and potential of wind farm projects, despite a "world-class wind resource" waiting to be tapped.

Study to determine if Coniston smokestacks can produce wind power

Wind and environmental studies will be conducted to determine if two 120-metre dormant smokestacks in Coniston can be retrofitted with wind-powered generation systems. The Northern Ontario Heritage Fund Corp. is investing $100,000 in the studies to be done at the former Inco Ltd. smelter in Coniston. The studies will explore the potential for renewable energy production in Greater Sudbury, said Northern Development and Mines Minister Rick Bartolucci, who announced the funding. Environmentally sustainable energy production is essential to making the North an attractive place to live, work and do business, said the Sudbury MPP, who chairs the NOHFC. Funding is being provided through the fund's Renewable Energy Program as part of the Ontario government's Northern Prosperity Plan. The plan aims to strengthen the North, listen to and serve northerners better, help the North compete globally and provide opportunities for northern residents.

Wind Chill

Hans-Armin Ohlmann had hoped his experimental and unusual wind turbine would usher in a revolution in energy production. But progress has been slow for the Ayr resident -- the wind just isn't there. "We've had very bad wind capacity -- exceptionally unfortunate," said Ohlmann, principal owner of Ventax Wind Power Inc. in Ayr. Stretching 90 feet high, the tube-like prototype sits on a farm just west of Ayr in Blandford-Blenheim. It is clearly visible from Highway 401, sitting on a hill on the farm of Phil Schiedel on Concession 11. Schiedel is a three per cent owner of Ventax and paid $120,000 toward the test wind-turbine project, said Ohlmann, who footed the remaining $130,000. There are no external propeller-like turbines on this design. They are internal, and flipped 90 degrees so they face upward. The mechanical energy of two vertical rotors is converted into electricity.

Canada should be in the race for nuclear fusion

There is enough deuterium for millions of years of energy supply, and easily accessible lithium for several thousands of years. With essentially zero long-lived radioactive waste, zero greenhouse-gas emissions and none of the safety concerns associated with fission reactors, one can begin to see the attraction of fusion power. It is the green technology with the most potential to make a real difference to the climate-change debate.

FERC to Streamline Ocean Energy Permitting Process for Pilot Projects

VANCOUVER, CANADA, July 23 /CNW/ - The United States Federal Energy Regulatory Commission (FERC) announced a proposal to shorten the permitting process for pilot ocean energy projects to as little as six months. As part of its proposal, FERC will convene a public hearing on licensing pilot projects in Portland, Oregon on Oct. 2, 2007. Finavera Renewables (TSX VENTURE:FVR) CEO Jason Bak said, "We look forward to the hearing in October and want to extend our thanks to the FERC commissioners and staff for the tremendous commitment they've shown to offshore wave energy development. This decision shows strong leadership in promoting a clean, environmentally friendly renewable energy source that has the potential to satisfy a significant portion of the total energy demand in the United States."

High-tech floating wind turbines

Ottawa, Canada-based company Magenn has developed a "floating wind turbine" for personal and infrastructure power generation. The helium-filled device floats up to 1,000 feet into the air, using high altitude wind gusts to generate power up to a kilowatt. The power is transfered down via two "tethers" attached to the turbine.
