Interest in wind power has Beach looking at controls

Posted to: Environment News Virginia Beach

VIRGINIA BEACH

It's no surprise that John Devan would want to install a 33-foot-tall windmill in the Corporate Landing Business Park to power his building.

Devan is president of the electric engineering firm Pace Collaborative and enjoys giving tours of all the energy-efficient light fixtures in his office.

What has taken Virginia Beach officials by surprise is the number of other business owners and residents who are inquiring about propping up their own windmills.

"I am averaging one or two calls a week," said Will Miller, a Beach zoning inspector.

It has forced Virginia Beach officials to explore ways to regulate the windmills and determine where they can be installed and what federal and state certifications are necessary.

"It is large, like a cell tower, and we think there needs to be some guidance," said Kay Wilson, an associate city attorney.

Beach officials are studying zoning codes from North Carolina and elsewhere in Virginia and looking at whether the turbines might spur noise, safety and visual problems.

Wilson said she hopes to bring an ordinance to the City Council in the coming months.

Suffolk officials are also developing rules for windmills after getting one request, said city spokeswoman Debbie George.

"It's a growing market segment," said Ken Jurman, the manager of the renewable energy program for Virginia's Division of Energy.

Last year, the state approved Virginia's first commercial wind-energy farm in Highland County, near the West Virginia border.

The mountains of Virginia and the coastline are the best places for wind turbines, Jurman said.

But it's still a pricey alternative for individuals, Jurman said.

Ocean Lakes High School intern J.T. Glaze, who worked at Devan's company this summer, calculated that it would take 24 years to break even on a $215,000 wind system that Pace Collaborative is developing for the Beach school division. School officials are considering placing a wind turbine at the new bus maintenance facility. At best, the turbine would provide power for 25 percent of the building, Devan said.

Most companies will only invest in an alternative energy, like wind, if they can recoup their money in five to seven years, Devan said.

That makes it tough in Virginia, he said, because the state still has relatively low power bills, and unless a business or house is right at the Oceanfront, there's not enough wind here to harness a significant amount of energy, Devan said.

Eric Richter, the vice president of property management for Phillips Edison & Co., said his firm came to a similar conclusion after considering whether to put a windmill at a shopping center off Shore Drive.

It is likely Phillips Edison will test wind energy in states with stronger wind zones, such as Texas, Richter said.

David Comer, who lives in the Ocean Lakes neighborhood, said he's interested in wind energy for environmental, not financial, reasons.

"I think it's something viable, that the city should consider letting residents do it in some way," Comer said.

Bring It On

Hey, if I can get free electricity from a windmill then put it my backyard, then I can leave the A/C on 24/7.

we need to copntrol our own consumption

You can argue back and forth and it won't do any good. What we need to do and start NOW is controlling our own consumption of fuel, electricity and water.

Wind power - lets give it a shot

We need to give wind power a shot, even here. Simple breezes blowing in from off shore could add up to a fair amount of power. Sitting around and not doing anything only leads to the continuation of the same problem: high energy costs and nothing being done about it. Once the investment is in, Mother Nature takes over. Photovoltaic (sp) are another good one, but they are expensive also.

We need to be looking for other sources of power out away from fossil fuels if we are going to get away from being dependent on them.

Let me define my numbers

You’re keeping me on my toes MC, but you comment has just increased my numbers. The turbines I based my numbers on run at 2kwh & 10kwh in 15 mph wind. I reduced the numbers by 75% to best show winds for this area, but based on your 5mph number I should have only reduced them by 64%. The records I have found show wind at the oceanfront to average 14mph and then drop to 6 mph at the Norfolk line (10mph ave). This is based on and elevation of 150’, and respectively the speed drops as you get closer to the ground. So really I’m basing my numbers on a 3.5mph wind. Can I use your 5mph instead?

Wind, methane, solar…

Hey Barney, I have an RV (trailer), and I have to recharge the batteries with my truck (very wasteful) or my generator (just as bad). Everything “but” the air conditioning can run on the batteries, and the refrigerator runs on propane. I brought up propane (portable natural gas) because not any “one” system will supply our homes energy completely. Natural gas (or propane) can and is being supplemented with renewable supplies (methane) like cow poop and landfills without a drastic need to change the systems. BTW, the natural gas (propane) HVAC unit I’m referring to only needs electricity to power blowers to move the air into the home. The key is that they don’t have compressors; they use an ammonia/water absorption process.

for immediate results

Cut back on your own consumption of gasoline and electricity. That's something we can all do and NOW, and will be the most effective, while we sit around and wait another decade for our government to come up with another hairbrain idea.

Re: Confused about working in averages

You can't use the rating because that just tells you the maximum it can do if optimal resources are available. The mechanism itself just handles conversion of what's already there. What's important is the natural resources around you. We're in a marginal to poor wind resource zone with winds below 5mph common. What you're going to get is far less than 25% maximum capability.

You can also pick all the fancy shapes you want but really what matters is the cross section to the wind. You can increase efficiency with better designs and the current state of the art gives you that 2.6 kwh at 5mpg with a square meter cross section. Also remember that energy is removed from the wind so you can't simply plant one of these at every house since they would block each other.

WIND POWER

Hay logic dictates the artical is about wind power not fossel fuels..I am sure Rvs and boats that use fossel fules for power are using generators as far as the HVAC industry yes some compressors are run off of gas engines which mean they use less electrical energy but they are using fossel fuels and how would this help the environment or stop our dependency on fossel fuels again the artical is about wind power

Bird safe?

Yes we did touch on it.
The anemometer styled wind turbines address both issues of noise and birds.

Cow poop

FYI, Barney. Refrigerators in RVs and boats are already propane powered, and natural gas air conditioning was put into the market back in the 30's.
Now if we can get them converted to use methane from cow poop and landfills, you will have a renewable resource.
That's "out of the box"…
