Temptations Abound! (or, the worst advertising script, ever!)

This past New Years, sometime in between mixing champagne and beer and recovering from the aftermath, I decided to let loose all my inhibitions and renounce meat for 2008. That went really well...for about 4 days when I happily scarfed two chicken Caesar salads in a single weekend. After that, I decided to allow myself the following exceptions:
  1. Fish and eggs--I figured I'd re-evaluate these for 2009
  2. Mom's cooking--she was NOT happy when she found out
  3. Philly Cheesesteaks--giving up some things would just be un-American
  4. Avoiding commotion--for example, avoiding a Jewish mother's concern for her guests' diet
So with these ground rules laid, I've done pretty well; no fainting spells yet, anyway. I'm still bad at cooking and thus frequent recipe websites for good vegetarian recipes. The following screen shot was so good that it revived me from my hibernation in the blogosphere:


Gee! That steak would go great with my vegetarian tofu stir fry!

I'll leave the reasons behind my new-found religion (not really) later, but this quote"Similarly, a study last year by the National Institute of Livestock and Grassland Science in Japan estimated that 2.2 pounds of beef is responsible for the equivalent amount of carbon dioxide emitted by the average European car every 155 miles, and burns enough energy to light a 100-watt bulb for nearly 20 days." in this article ("Rethinking the Meat-Guzzler") sums it up neatly for a solar engineer driving 30 miles to work every day...

In other news, two extensions of the Solar Investment Tax Credits are floating around in Congress ("SEIA Breaking News"). Hopefully the House and Senate can resolve their differences quickly!

What a selfless lot we are...

According to this BBC article, 80% of the world is ready to make sacrifices for a greener future.

Pretty optimistic, neh? Well let's dig a bit deeper (like the eternal cynic that I am). 83% said lifestyle changes will definitely OR probably be necessary. In fact, only 46% said that lifestyle changes will definitely be necessary. Oh details, how slick you are. Sorry for being pessimistic but saying lifestyle changes will "probably" be necessary when no exact figures or examples are given is like saying, "yeah we'll deal with it when we have to...and then we'll make a big fuss about it." Given climate change, which indicates that our lives are out of balance with nature pretty much means that we're going to have to change or be changed. Thinking about hybrid cars versus gasoline cars is a lifestyle change. Buying more efficient lightbulbs is a lifestyle change. Walking more and driving less is a lifestyle change. Come on, who do these people think are going to make the difference? It'd be like everyone sitting on the couch ravenously watching Reality shows on TV and then wondering why the big, evil corporations keep showing the crap... oh wait, I think that may be a little bit too true already.

The Earth isn't magically going to become greener because we wish it. Sure, some people (who actually care) will come up with some nifty energy-saving or waste reduction ways, but none of it is going to be technological silver bullet that slays the beast of our energy-hog lifestyles. This is my number one frustration with people: they see an article about how some family in Northern California doesn't have an energy bill because of solar panels on their roof and then they want solar. And when we assess their energy usage and see that they're hitting 9 kW peak when they can only fit 3-4 kW (for $30-50k, I might add) on their roof, they begin to doubt solar. First, stop setting your AC to 60 during the day while you're at work, and then we'll start talking (As a side note, I never understood why it's such a pain for people to bear the 10 minutes that it takes for the AC to kick in when they get home from work... have some perspective, really).


Well digging even further into the full report, we see that the U.S. has the fourth (out of 21) most people that believe changes won't be necessary. Furthermore, only 48% think change will definitely be necessary (better than the average at least...). None of this bodes well for the country that spews more carbon emissions than entire continents. The U.S.'s response ranks right there with India's. Does the average Indian need to change their lifestyle to assist with global warming? Probably not. Yet MORE of them are willing to change it (probably for the worse) than us. At least our neighbors to the south and north see it differently (probably from years of sucking on our pollution)--Mexico and Canada have the 2nd and 3rd most people that think changes will definitely be necessary. Seriously, more Mexicans are willing to take a hit to their lifestyles than Americans? Open those borders up now, please.

So while I was initially excited by this article, I am now just a combination of pissed and sad, as tends to happen when I read about the environment in the news. What I have learned today is that either Americans are too self-absorbed in materialism or that they're blindly faithful to technology. Currently, my hope is not abundant.

Yet another reason why a renewable fuel alternative is necessary

In my mind, renewables are the energy equivalent of a fixed interest rate and by that same token, fossil fuels are variable interest rates. With renewables, you can lock in at a rate that might be higher than fossil fuels, but will stay the same.

Take solar power: you purchase all of the hardware upfront, but after that, you only have to worry about some minor upkeeping costs (except if you use batteries...and you have to switch out your inverter eventually).

On the other hand, with fossil fuels, you have to ride the highs and lows, which is just stressful. I remember when I started driving (back in 2001ish) and gas prices were under $1/gallon. No one was thinking about alternative fuels then. But now that prices have almost tripled since then, everyone's stressed out about impending oil and gas shortages. Maybe in 5 or so years we'll dip down to those levels again (doubtful), but the price will just rise again. Personally, I'd rather just pay more upfront for sound energy and sound mind.

Anyway, this article reminds me of Amory and Hunter Lovins' Brittle Power, which I haven't read completely.

From Nairobi to Tehran

Costly Fuel Is Never Far From a Match

THERE are deep roots to Myanmar’s current unrest, pitting its repressive regime against Buddhist monks, but the immediate spark was the junta’s unexpected decision in August to double fuel prices. Overnight, diesel prices skyrocketed, and compressed natural gas rose fivefold.

In this respect, Myanmar is not an isolated case. Rising oil prices in recent years have created all kinds of headaches as they have rippled across the world. Many governments, especially in the developing world, have had to choose between raising domestic subsidies to offset the increases or letting the people bear the brunt.

Neither choice — higher government spending or the risk of popular discontent — has great appeal.

In oil-rich Iran, civil unrest spread through Tehran this summer after the government rationed gasoline in an effort to curb the country’s addiction to cheap fuel; gasoline in Iran, imported because the country lacks refining capacity, is heavily subsidized and cost about 40 cents a gallon at the time. After two days of upheaval, the Islamic theocracy restored order and kept the policy.

In Nigeria, the outcome was different. Striking oil workers in June threatened to shut down the country’s oil production if fuel subsidies were dropped. Faced with the threat of losing its biggest source of revenue, the government quickly backed down.

Fuel prices go to the heart of people’s ability to move, stay warm or feed themselves. So it is no surprise that governments around the world have tried to blunt the effects of oil prices that have tripled in the past four years.

But interfering with energy markets can be a risky and costly game. Prices kept high by market forces and taxes dampen expectations of cheap fuel. Fuel subsidies do the opposite, and countries that rely on them play with fire.

“Some countries are hiding the reality of high fuel prices to keep political peace,” said David L. Goldwyn, an assistant secretary of energy during the Clinton administration. “Nigeria caved, but it’s not a sustainable strategy. The more they do it, the more they pump up demand with cheap energy.”

The problem is that fuel subsidies can quickly add up — especially when oil prices keep rising as they have since 2003. It has been estimated that Yemen, for example, devotes 9 percent of its gross domestic product to holding down energy prices.

Only a handful of countries provide very high subsidies on their retail fuel sales. These include Venezuela, Turkmenistan, Syria, Algeria, Angola and Malaysia, and, unsurprisingly, most of them are oil producers.

In fact, most countries have allowed domestic prices to creep up. Drivers in Tunisia, Honduras and Pakistan all paid more for their gasoline than Americans did last year, according to a survey of fuel prices compiled by GTZ, a German consulting firm. The survey found only 20 countries where the price of gasoline was below $2 a gallon, that is, lower than the cost of refining it.

In most European countries, the opposite is true. Governments slap on high taxes — sometimes as high as 80 percent of the cost — in part to discourage consumption. In the Netherlands, gasoline cost $6.40 a gallon last year.

In the United States, where taxes represent about 20 percent of gasoline prices, regular gas averaged about $2.35 a gallon last year. It’s up to $2.80 these days. Still, the mere mention of raising gasoline taxes remains almost tantamount to political suicide.

When it comes to energy policy, the most closely watched country is China, whose surge in demand has helped propel oil prices upward. China needs to finely balance its need for growth while trying to keep a lid on energy use, both to control pollution and to keep prices from skyrocketing.

Though pollution has taken a toll on China’s environment, the restive demands of the rural have-nots left far behind by the urban haves cannot be ignored. Last year, there were 90,000 protests against local governments, according to Michael Green, a senior adviser at the Center for Strategic and International Studies.

In most cases, fuel prices were not the cause of these protests, Mr. Green said, but they point to the risk of upheaval China faces: Each year, 20 million people move to big cities from the countryside in search of work.

“The mandate of the Communist Party is economic development,” Mr. Green said. “This is why it is so hard for them to ration energy demand. It’s very difficult for the leadership in Beijing to develop a harmonious society if they cap energy demand.”

Still, the Chinese leadership has been gradually allowing fuel prices to increase, although its domestic state-run refineries still sell gasoline at a loss.

Indonesia illustrates the risk for authoritarian regimes. In 1998, large-scale student riots sparked by higher energy prices led to the fall of the autocratic president, Suharto. But in recent years, the Indonesian government has managed to cut back its subsidies without sparking dangerous riots.

“The more authoritarian the regime, the more vulnerable it is to mobilized dissent when they try to raise energy prices,” Mr. Green said. “When democratic institutions are stronger, governments have been better able to manage energy demands. That’s the lesson from Indonesia.”

Ugh, utterly disgusting and atrocious

This post is in response to Rule to expand mountaintop coal mining in U.S.
by John M. Broder

Ugh. Try as I might, I can't even be open-minded or unbiased about this. For those of you that don't know, Mountaintop Coal Mining (often "affectionately" deemed "Mountaintop removal, Valley fill") is the process of (literally) blowing off the top of mountains (sometimes up to 1000 ft.) to remove rock and dirt above the underlying coal seam. (Oh, don't worry, the trees are sold as timber and the top soil is saved for reclamation... And well, screw everything that might have been living there...) This rock and dirt (called "overburden") is shoveled away into local valleys, effectively "smoothing" the landscape, polluting the water system, and flat out destroying rivers and streams. Coal is then mined (ripped out, more like it) by huge dragline excavators, that can remove hundreds of tons in a single cycle.

And after the coal's been pulled out, the companies throw the topsoil back on and plant non-native, fast growing grass (as per regulations by the Office of Surface Mining). Problem is, these grasses don't allow native trees to take root, and effectively render these "restored/reclaimed" areas all but useless. In fact, the most popular uses for these areas tend to be shopping centers, golf courses (where the execs of mining companies can circle-jerk with all of the politicians they're in bed with--sorry, I told you I couldn't be objective), and amazingly enough, small airports...

Basically, the people of Appalachia (where Mountaintop Removal occurs) are getting fucked. There's no lighter way of putting it--their homes are destroyed by the shock of the blast, their water systems are being polluted, and even worse, they're not even able to capitalize on the alleged economic benefits because the industry is screwing them out of jobs. From 1990 to 1997, when Mountaintop Removal caught on, 10,000 mining jobs were lost in Appalachia. The poorest region in America got a whole lot poorer.

So what's all this mini-hoo-ha now? Well basically, the Bush administration is trying to "clarify" the Office of Surface Mining's (OSM) regulations. You can be sure their "clarity" isn't exactly going to be very stringent on mining companies. At the center of this debate is where mining waste goes. In 2002, the a district judge stopped new permits on Mountaintop Removal because dumping the fills near streams were in violation of the Clean Water Act, but the decision was overturned by the Appeals Court in 2003. This debate is similar, in that language that prevented the removal of waste within a certain proximity of streams is being softened to "limiting the amount of waste" or some such bullshit. That's as far as I can make of it, though it is 3 a.m. so feel free to correct me. Basically, it'll make mining easier and cheaper, while completely disregarding the environment.

What pisses me off the most are statements like: "A spokesman for the National Mining Association, Luke Popovich, said that unless mine owners were allowed to dump mine waste in streams and valleys it would be impossible to operate in mountainous regions like West Virginia that hold some of the richest low-sulfur coal seams" as if screwing up our environment is doing our nation a SERVICE. Honestly, where do these people get off? Uh, how exactly did you operate BEFORE moutaintop removal? Oh, that's right, you actually employed thousands of workers. But boo-hoo, if you can't throw your shit (literally feces of mining) into our water and ecosystem, you can't enjoy the lucrative profits you're now experiencing. Note that I'm not advocating coal mining, but look, if we can't switch completely to clean forms of energy, let's at least control the impact we have on our environment.

Basically, I'm pissed off because rich, profiteering fucks hold the nation's impoverished at gun point, and while they're busy pickpocketing the poor, they're blaming the rest of America for forcing them to pull the trigger.

P.S. What can we do? Eh, at this point, maybe not much. One step is to send in a comment to the Office of Surface Mining (http://www.osmre.gov/news/082407.pdf ) and they'll include your comment on their final (bloated) report. hooray.

A better alternative is to write to your congressman. There's a bill floating around (HR 2169) that promises to strengthen the Clean Water Act by preventing Valley Fill. (Here's one link to support it: http://www.ilovemountains.org/action/write_your_rep/).

Or just shoot a coal mining exec or an OSM lackey. I mean...

Deep Pockets for Short-sightedness

This is in response to the recent NYTimes article: It Takes Deep Pockets to Fight Global Warming

A quick summary: Michael Fitzgerald contends, in a non-pro or con article, that global warming will require billions to fight. Technologies such as carbon sequestration only get $100 million a year out of the $2 billion cut for clean-coal technology. Among other ideas Fitzgerald presents are >$5 billion satellites that capture solar energy and beam it back to earth, multi-trillion dollar sun shades and [my personal favorite] shooting particles in the air to reflect the sun (the parasol effect). Included is a venture capitalist (who helped invent Ethernet) who, "is surprised that the parasol effect is not getting serious research dollars, because it looks like the simplest and easiest way to deal with global warming. For one, it doesn’t rely on reducing carbon dioxide emissions." But it is too risky to be funded by short-sighted venture capitalists. And finally, "But [David M.] Reiner at Cambridge [a lecturer at MIT] expects that climate change will eventually become a research priority, much as the Strategic Defense Initiative, the space program and the Manhattan Project did. The problem won’t go away. Neither will the ideas."

Firstly, I understand that the section that this article fall under is "Prototype," where the goal is to show off new technologies. Unfortunately, these ideas have been given credibility--either that or proven technologies, such as solar, wind and geothermal are seen as unfeasible. Whatever the case, there's a problem when the general population believes that solar panels on a million roofs and a satellite beaming energy from space are equally feasible (read: solar panels = proven to work, beaming from space... not. so. much).

There are multiple problems with the proposed technologies in the article. Fore-mostly, none, except for beaming solar down to earth, deal with the inherent causes of the problem: we are producing too much CO2 and other greenhouse gases (GHG). Carbon sequestration and parasoling are band-aids. By avoiding cuts to our GHG emissions, we license continued and increased emissions, inevitably driving us towards scenarios where we either run out of space to store our CO2 or worse, we've saturated our air with so many particles, it's become dangerous to our health.

Personally, I think parasoling is out of the question. Throwing "particles" (read: chemicals) into the air sounds like a recipe for disaster. If committed to this scenario, I am certain we'll be faced with a dangerous trade-off: health versus effectiveness. In addition, as we emit more heat trapping particles, we'll have to emit more light reflecting particles, creating a scenario in which we have to constantly maintain balance. Furthermore, considering GHG effects often lag emissions by decades or more and is currently imperfectly understood, it may be a century before we actually do anything. By then, say goodbye to Bangladesh.

The biggest problem with carbon capture and storage is that it is most feasible with large, centralized production of carbon (power plants). While this may remove a large amount of our CO2 (I'm still not convinced that these storage sites are impermeable as many scientists contend, but I haven't read a lot on it), a significant portion of our emissions come from transportation. And here's the trade-off: carbon capture technology on vehicles = reduced fuel efficiency--assuming that capture and storage of carbon from vehicles is even possible.

And beaming solar energy? To the average person, it might seem no different than sending cell phone, TV, or radio signal from space, but in fact, it's hugely different. Antennas don't need a large amount of energy to transmit a signal. Essentially, you just need to transmit enough energy so that it gets through the atmosphere and still has enough definition to be distinguished from random signals (noise). But for power usage, you need to transmit that power. The article talks about $5 billion systems that could power a small city. We're talking somewhere around a couple hundred MW of power. So basically, you're focusing all of that energy into a tiny beam and shooting it at the earth. Eep! Not that I don't trust technology, but I don't. The tiniest mismatch basically creates a solar powered death beam. Furthermore, this is essentially what you'd be doing: taking energy from the sun, shooting the energy down from the sun to earth, and then harvesting that energy. Why waste billions of dollars to do what the sun does naturally (sending energy to the surface of the earth)? (okay, so you might get a few points of efficiency, but considering the cost of shooting things into space, it's probably not cost-effective. There are better ways of increasing solar conversion efficiency).

My point is, solar energy, the way we do it now through panels on the earth, has the potential to occupy 30% of our electricity grid; at current trends, solar electricity through panels on a roof could be cost-effective without government subsidies in a decade. Energy efficiency and conservation through higher fuel efficiency standards, better weatherization, and not using as much energy, has the potential to save carbon emissions in fractions of the aforementioned costs and can be deployed almost immediately. The old adage of shooting for the moon with global warming lands us among the stars of huge debt and little solved. Instead, by advocating technologies and practices that are available and viable TODAY, we can usurp the causes of global warming, mitigate the effects of fossil fuel pollution, and SAVE money in the future.

It doesn't take deep pockets to solve global warming; it takes people interested in practical, cost-effective strategies that are truly committed to solving the problem, rather than lining their own deep pockets.

A Solar Design Engineer?!

So this will be very quick, but about 5 hours ago, I accepted a position with the Solar Design Associates as a junior Electrical Engineer! Somehow, I was able to take my not-3-to-5 years of experience and convince them I can handle the job of a solar electrical engineer!
You might ask, what does a solar electrical engineer do? Well, so did I, until yesterday when I made a few calls just to figure out what to expect. Obviously, it ranges from company to company so I'll stick with the description they gave me today at SDA.
A solar electrical engineer does... EVERYTHING. Well, at times, it seemed that way. And of course, none of it was really taught in college, unless you count the little bit of CAD (which we learned on our own anyway) and basic electrical properties (volts, amps, watts... and short-circuits are bad--again we learned that last one on our own anyway).
Right, so first there's the siting. Someone wants a solar system and one of us has to go down there to take a look; we're trying to get a basic idea of what the place looks like, what it will accommodate and if there are any really obvious issues (shading from other buildings or trees, etc.)
Then we take all that data and draw it all up on CAD. Whooooosh! Magic! Well, this part will be one of my larger challenges as I haven't really used much CAD beyond drawing lines. Now they want me to draw pretty lines that people base building things on. Eek! We also need to design the solar array--where it goes, how it's arranged--physically and electrically. There are a lot of structural and aesthetics to consider--eh, I'll probably have to pass all of that off to the more experienced people.
Then there's the approval, by the utility, by the client, by the government. Eep! And I have to be there presumedly every step of the way, reassuring people that it won't blow up and kill someone. Which, hopefully it won't.
And finally, after everything has been approved, it's time to go make sure the installation is up to par. Thankfully, we contract this out, so you won't see me trying to lift a stack of panels to any roofs (I'm sure many of the clients will be happy about that). Well, almost finally, anyway. I suppose we also give them any technical support they may need later. Oh, and I almost forgot--I might have the opportunity to apply for solar incentives for them. I know, it may not sound exciting to you, but for me, after working with people who try to get governments and utilities to approve solar incentives, I think using incentives will make them happy.
Anyway, what I like about all of this is how diverse the tasks are. There certainly should be no boring parts. Now, if only I can find a place to live...

Solar iPod Charger?

A couple of companies have a solar iPod charger available (1, 2), but for $100?! Okay, okay, they're well-packaged and honestly not over-priced. But as an inspiring solar guru, I think I can do better. Besides, as Martha Stewart says, "You own it if you made it." Thus, like any good solar player, I'm going to announce my intention (rather than announcing it when it's complete--come on I have a real dearth of posts here...) to build a solar-powered iPod charger. Shouldn't be too hard as long as I can get the specs for iPod charging and find a cheap onesies solar cell distributor.
So, knowing full well, that nobody reads this blog at this point, if y'all have any information or advice, let me know!
