Disagreement over threat to national security

Cape Wind claims to have cleared another hurdle today. From their press release:

Today's Department of Defense (DOD) report is good news for Cape Wind. The report clearly finds Cape Wind to be outside of the wind-turbine offset zone being proposed for PAVE PAWS radar systems.

Now the DOD has reached the same determination as the U.S. Air Force -- that Cape Wind will not negatively impact the Air Force PAVE PAWS radar system. This report puts to rest in a final form any reasonable concern about this issue.

The reality is that projects like Cape Wind strengthen national security by making America more energy independent and less reliant on foreign sources of energy.

That's not how the Alliance for Nantucket Sound sees it, unsurprisingly, claiming that this report is final proof that the turbines would threaten missile defense systems and therefore, national security.

These two just can't agree on anything.

Built to scale

Small and medium size wind generators of about 100 KW each are playing an important role in the power supplied by the Alaska Village Electric Cooperative (AVEC) -- a non-profit customer-owned electric co-op serving 52 villages throughout interior and western Alaska.

Wind power on this scale, and in these conditions, is not cheap. Unlike megawatt scale wind turbines which cost around $1,600 per KW of installed capacity, these smaller generators run around $10,000 per installed KW. Part of that cost is simply a matter of buying on a smaller scale. But according to Brent Petrie, Key Accounts Manager for AVEC, the harsh Alaska conditions are responsible for much of this cost. Building in permafrost has always been tough, especially when that permafrost undergoes seasonal melts that turns it to mush and marsh. As an environmentally sensitive utility, AVEC is careful to minimize damage during installation. Overall, electricity costs from such small scale generation are estimated by Petrie to run around 15 cents per kWh -- three to four times the price of larger scale wind farms in milder conditions.

But the same conditions that drive the price of wind electricity for the AVEC customers drive up conventional sources even more. Fuel is shipped by barge to the small isolated communities, or even flows in, meaning that electricity is supplied by diesel generators run on the most expensive of fossil fuels. Since transporting large amount of fuel is an expensive prospect, normally fuel is delivered only once a year.

According to Petrie, AVEC tries to make sure that as a cushion each village has storage capacity for 13 months of fuel. Building a diesel storage facility on permafrost is an expensive prospect too. Combined fuel purchase, shipping, and storage for diesel in these villages runs between 13 cents and 25 cents per kWh -- even before purchase and maintenance of generators is considered. Overall, electricity to these villages averages 45 cents per kWh; so the 15 cents per kWh for wind electricity represents a real savings.

A man ahead of his times

I've always thought that Edison's notion of using DC instead of AC would've resulted in a better energy situation -- more locally produced power through cogeneration and other sources, and better storage capability. But this New York Times piece on how he worked to build an electric car, and his dream of powering every house with its own wind generator, puts him squarely ahead of his time.

A concise introduction

The great question about wind is intermittency, and the great answer is energy storage. There are a number of energy storage technologies out there; I suspect the right storage mechanism will differ from region to region. One of the most interesting storage options out there is pumped hydro. The concept is pretty simple: you build […]

An insider’s view of the wind industry

Be sure to check out a fascinating post by Jerome a Paris (who helps finance wind power projects) on the state of play in the wind industry. Here’s the spoiler: Anyway, the conclusions I draw from all if this are as follows: windpower is booming, and is reaching a stage where it becomes a noticeable […]

Man wants to put wind turbines on his ailing farm

Opposition from neighbors drives man to suicide. And you thought the rich whingers at Cape Wind were irksome!

Wind-loss, wind-gain

On the heels of last week's apparent defeat of the proposed Hoosac Wind project in mountainous Western Massachusetts due to environmental (wetland) concerns, Massachusetts' new governor has put his voice behind further offshore wind projects. The timing is interesting.

Solar is making boats go now — take that, wind!

Wind, you think you are so badass. I tell you, solar is creeping up on you where you least expect it:

On a new McKibben editorial

If this were the daily sunset you had gotten used to growing up, you would understand the hesitancy of even Bill McKibben, a renowned environmentalist, to okay wind turbines on the horizon, interfering with bird migration in order to generate electricity.

However, in an opinion article in which McKibben confesses his sentiment, entitled "One world, one problem," he ultimately resolves:

In this world, the threat to that landscape, and to those birds, comes far more from rapid shifts in temperature than from a few dozen towers.

McKibben goes on to write a testament to the gravity of climate change and its meaning for the environmental movement, which the existential call for action is uniting. No matter your top concern -- clean water, dolphin populations, crop survival, energy consumption -- there is a link to climate change and a bigger picture to keep in mind.
