On the third day of Christmas a Model S for Dee

It was only a few months ago that I happened across a Tesla showroom, and I do use the term showroom loosely. There was one (very very nice) car in the showroom with about 40 customers drooling over it (including me). I stated that the Tesla would be my next car, I was so impressed. Then I found out that in order to take the car for a “test drive”, I needed to leave a (fully refundable) $5,000 deposit to go towards an order for my very own Tesla, which incidentally takes 11 months to get one made for you. I started to wonder…Would I really want to spend $100K plus on a new car. Heck, I could almost buy a house for that price!

I found out this morning that the Tesla won the automotive industry’s equivalent to the Grammy for Best Motion Picture. Judges have unanimously voted the Tesla Model S the 2013 Motor Trend Car of the Year. The U.S.-manufactured electric vehicle (EV) becomes the first vehicle to win the award not powered by an internal combustion engine in the 64-year history of the publication.

In 2010, the Department of Energy backed Tesla Motors, Inc., with a $465 million loan for the construction of two manufacturing facilities, one in southern California for the Model S electricsedan and one in Palo Alto, California, for electric powertrains. The Palo Alto facility is for assembling electric vehicle battery packs, electric motors, and related electric vehicle control equipment, both for Tesla's own electric vehicles and for sale to other automobile manufacturers. The Tesla offers three lithium-ion battery packs for the Model S that are designed to provide ranges of 140, 200, and 265 miles per a single charge. The 2012 model has an EPA combined city and highway rating of 89 miles-per-gallon equivalent.

Santa, I would like a new RED one just like the one in the picture for Christmas. You don’t have to bring in down the chimney, parking it in the driveway with a big gold bow would work just fine.  Thank You!

Shift in Energy Balance Includes Renewables, Efficiency

Editors note: when I read this, and then watched the videos from the WEO launch (included for your viewing pleasure below) it took all my self control to not jump out of my chair and scream "BOOYEAH".  And yes, I even thought of calling some EE non-believers out there and booyeah-ing them, however I'm a lady first and foremost, so I kept my glee to myself. 

Now, more from Dee...

All of us here at the SJVCEO have been preaching to anyone who will listen about the power of energy conservation. Well, now we can back that claim up with some pretty substantial clout. The International Energy Agency (IEA) released the 2012 edition of the World Energy Outlook (WEO) on November 12th. In that report the IEA states that North America leads the shift in global energy balance. That shift includes a movement to renewable energy and energy efficiency that will have a major impact on global energy and climate trends. North America is at the forefront of a sweeping transformation in oil and gas production that will affect all regions of the world, yet the potential also exists for a similarly transformative shift in global energy efficiency. According to the WEO, we can achieve energy savings equal to nearly a fifth of global demand in 2010. In other words, energy efficiency is just as important as unconstrained energy supply, and increased action on efficiency can serve as a unifying energy policy that brings multiple benefits.

The report calls out six areas that need to be addressed in order to make the “efficient World Scenario,” a scenario that shows what energy efficiency improvements can be achieved simply by adopting measures that are justified in economic terms. The steps include making energy efficiency clearly visible along with its economic gains, as well as including efficiency concerns into decision making in government, industry, and society. The IEA report urges policy leaders to deploy a mix of regulations to discourage the least energy efficient approaches, while incentivizing the most energy efficient actions.

The report also projects that renewable energy sources could become the world's second-largest source of power generation by 2015, closing in on coal as the primary source by 2035. The projection noted that this is based on continued subsidies, which amounted to $88 billion in 2011.

Believe it or not: world's longest turbine blade

When Dee saw this headline she was so impressed she whipped out a quick BION post, which means I have Thursday off!  Thanks, Dee! 
Siemens, a manufacturer out of Germany, has found a reason to build this incredibly large off-shore wind turbine, and has plans to build a total of 300. This reminds me of something my brothers would have enjoyed working on as kids. The blades on these puppies are incredibly large (75 meters) that’s equivalent to just over 246 feet. 
Hummm, to put this into prospective let’s just say the blades are about the same size of 2 and a half football fields, 1 and a half Olympic size swimming pools or almost three times the height (at its highest point) of the Golden Gate bridge. Now, double that for a whopping 154 meter span but still weights less than more typically produced blades by using lightweight materials during construction. The entire blade is made of a single piece of “glass fiber-reinforced epoxy resin and balsa wood”. Balsa wood? Yes, that’s right, balsa wood.
Not knowing my wood that well, I had to look up what the heck balsa wood was and if it was a renewable resource. Come to find out it is native to southern Brazil and northern to southern Mexico, but is found in other countries such as Indonesia, Thailand and Papua New Guinea. The best part is that it is a pioneer plant (or as my dad would have said, it’s a volunteer), plants itself in clearings in forests, wither man made or where trees have fallen, or in abandoned agricultural fields. It grows extremely rapidly which explains the lightness of the wood, lower density even than cork, and about 60 percent of the world’s supply comes from balsa plantations that grow it in densely packed patches and harvested after 6-10 years.
Okay, back on track, besides it being lightweight in relation to its size the construction processes also makes the wind turbine extremely strong. A really great asset to have when they will be hit with the energy of about 200-tons of air per second out in the sea!
According to Siemens the tips of the 75 meter long blades will be able to move at up to 80 meters per second or 2.16 mph. So, my mind starts to wonder, why so big? The answer is actually simple. As the turbine blades get longer the amount of electricity they produce increases very rapidly. Because offshore wind projects are quite expensive it makes sense to build a few big wind turbines than lots of small ones.

Money Monday: Smart Grid Funding

The U.S. Department of Agriculture (USDA) on October 11 announced funding to modernize and improve the efficiency of rural electric generation and transmission systems. The announcement includes additional loan support of $134 million in Smart Grid technologies in 16 states. The selected projects are located in Alabama, California, Iowa, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Mexico, New York, North Dakota, Ohio, Oklahoma, Texas, Washington, and Wyoming. 

In September, the USDA reportedthat it had met its goal to finance $250 million in Smart Grid technologies in fiscal year 2012.

USDA also announced nearly $264 million in loans to partially finance wood-burning plants in Colorado, Hawaii, and Texas that are expected to generate 69 megawatts (MW) of electricity. Additionally, $14,565,000 was announced to finance the construction of a 5.5 MW solar-powered generating facility in Maryland.

In California, Kirkwood Meadows Public Utility District received $50,000,000 to build or improve 40 miles of lines for distribution and transmission, and to make other improvements to their aging system.

Whitepapers: PV inverter performance in desert-like locations

Wow, unique desert challenges addressed through rigorous testing!

On April 25, 2012 SMA America, LLC publish a study on how outdoor installed PV inverters held up under extreme weather conditions found in the desert. Conditions such as sandstorms and enormous temperature swings produce a whole new set of challenges for developers of PV inverters. Dust and sand is prevalent in the ambient air and tends to create serious obstacles in solar PV inverters installed outdoors, but with the new technology developed and rigid testing the inverter’s seals protected it from harmful dust deposits.

I don’t know about you but this stuff gets me excited. I’m really enjoying watching alternative energy develop in front of me.  We are indeed watching history in the making, but let’s not forget that energy conservation, although not the most attractive option is the best way to become energy independent. Check out the full story at the link below.

Money Money: 10 ways to save on heating bills

California has been having an extended summer, especially here in the San Joaquin Valley where we've been experiencing 95+ degree temperatures into October, so late last week I got ready for work and put on a sundress.  To my surprise it had rained and my car--which of course was just washed the day before--was wet! 

Hmm, perhaps the sundress was a poor choice?

The quick turn to real fall weather got me to thinking about the impending winter, and since my job is what it is my thoughts immediately turned to my winter energy bills and what I can do now to save this winter.  

Here are 10 things you can do right now to help lower your energy costs this winter:

1. Check Your Insulation. If you haven‘t looked in your attic lately (or ever!) then get up there and take a look around to make sure the insulation is in good condition. Make sure there are enough air pockets to trap cold air. Old insulation can become brittle and ineffective so if your insulation is not doing the job it might be worth the time and energy to replace it.

2. Check Your Windows. You can lose a lot of heat through the cracks around your windows and the windows themselves. Check each window and make sure it is well sealed. You can buy kits that will help you test this. Be sure to caulk and seal around windows where you find leaks, and replace any interior seals that are damaged. If your windows are old, it might be worth the money in the long run to replace them with new triple pane replacement windows.

3. Weather Proof Your Entryways. Along with the windows, check your doors for drafts. Using weather stripping around the doors will help keep your heat from leaking out and the cold from getting in. 

4. Get a Ceiling Fan. Just like you learned in 4th grade - heat rises so you want to keep the warm air down in the room, especially if you have high ceilings. Most ceiling fans have a switch to reverse the direction so you can use them for cooling in the summer and pushing hot air down in the winter. Be sure you run it in the right direction or you might end up with cold air in the winter and warm in the summer!

5. Shut Off Unused Rooms. If you have a room or rooms that you don‘t use, keep the doors shut. Try to remember to shut doors if you will be in the room for a long time. Rooms which are used only sometimes will have the door fanned which allows cold air to escape into your others rooms. This, in turn, will make your furnace work harder and increase your heating costs.

6. Let The Sun Shine In. On sunny days, open your curtains and mini blinds but make sure you close them when darkness falls or on cloudy days. Getting insulated curtains can help keep out drafts from around the windows.

7. Get A Door Alignment. Over time, doors can sag and get out of alignment. Take a good look at your doors to see if they still fit in the casing properly. If they don‘t then adjust them for a tight fit.

8. Have Your Furnace Checked. Spend the money to have a professional give your furnace a checkup to be sure it is working at peak performance. This is important not only from a cost perspective but also from a safety perspective. A system that is not running as efficiently as it can cost you money in heating bills so the money to have it inspected will be well spent.

9. Change Your Air Filter. Air filters can get clogged with ends up costing you money in fuel - it causes your heating system to run inefficiently and can be a safety hazard. Changing out the filter once a year is a good idea and something you can do yourself with minimal cost.

10. Close Your House Vents. House vents allow circulation of air during the warmer months but it’s a good idea to close them at the end of fall before the real cold weather comes. Cold air seeping in can drive up heating costs and make your house feel drafty. (Best not to use a cat to close the vents, but in a pinch it will work!) 

Taking the time to follow a few of these tips will result in lower heating bills. Also, check out your energy providers’ web site for suggestions on how to practice energy efficiency and save money at the same time.

For those in the San Joaquin Valley ere are links to PG&E, Southern California Edison, and Southern California Gas Company. All three sites have great suggestions on saving energy. Of course, you can always find energy and money savings tips over on our website for VIEW the Savings!

Smartphone Solutions for Energy Problems

While doing research on a completely different topic I ran across a study that predicts smartphone usage will increase by 2600% by the year 2020.  If that is truly the case what is in store for smartphone technology in our future? 

Well, by 2020 smartphones are predicted to replace cash and credit cards as the preferred payment method. However, what I found most interesting is the advances in gadgets that will save energy and pay for themselves in a relatively short time such as the smart and Apple-esque thermostat designed by Apple alumni and iPhone designer Tony Fadell. 

As reported on Green Tech Media, Tony’s “Nest” thermostat distinguishes between radiant heat systems, heat pumps, and forced air, with a thermostat profile optimized for each system type. There are temperature sensors, humidity sensors, and ambient light sensors. Power comes over existing thermostat wires, which makes it compatible with 85 percent to 90 percent of American homes. The team wanted to make the product beautiful but unobtrusive. It's fair to say that the team succeeded -- the thermostat is a sleek piece of design that clearly betrays its Apple roots.

Thermostats need to turn off at night and turn off when we go away. They do not command the emotional connection we have with smart phones. It will be an enormous challenge for Nest to recreate the excitement of an entertainment product in a utilitarian device like a thermostat. But these engineers have overcome enormous challenges in the past.

Who? How? When? Is Solar ever going to be really affordable?

Recently I checked out how much it would cost me to put solar on my house. To my surprise, it was much more than I wanted to spend, especially since I’m not convinced that I really want to stay there for more than five more years. The economics of it just didn't add up. I had question like: Who would pay for the remaining balance if I decided to sell the house before the solar units were paid for?  Would the house actually meet an appraisal value that would include the cost of solar in the sales price? 

Unfortunately, the financing options for me weren't exactly attractive and leasing didn't appeal to me either.  Lucky for me and you, the Department of Energy (DOE) has just launched a new competition that could solve my problem.

The DOE has developed the SunShot Initiative, a collaborative national initiative to make solar energy cost competitive with other forms of energy by the end of the decade.  The first step in this aggressive endeavor focuses on removing municipal barriers such as permitting and structural engineering cost (which SJVCEO is a named partner with Optony, Inc.under The Solar Roadmap). 
Now, the DOE is going one step further by launching the SunShot prize competition, a very unique competition. This competition is working to install solar energy systems at a fraction of today’s price. The SunShot Initiative is reducing the installed cost of solar energy systems by about 75% and will drive widespread, large-scale adoption of this renewable energy technology while restoring U.S. leadership in the global clean energy race.

What is Localism? Can it really work in Fresno?

lo·cal·ism [loh-kuh-liz-uhm] : a philosophy that puts a priority on local economics.

Simply put, it is the idea of buying local, local control of government and the promotion of local history, culture and identity.  I ask why have we not embraced the idea years ago? With the eclectic population we host in the area there is an endless supply of culture and diversity that the mainstream public doesn't even know about or have the opportunity to enjoy. Now, throw in the reduced carbon footprint and cost savings that localism promotes and Fresno has the ideal mix for a successful localism movement!  

We can promote this idea more.  We must promote this idea more. 
I do realize Fresno has a “buy local” campaign, (I don’t live in a cave all the time) but we as a public need to start thinking differently. It is time to change the status quo and start acting (not just thinking) outside the box. We need a more walk-able  livable and climate friendly community to leave as a legacy for our children and grandchildren.
In theory, localism sounds great and it’s something Craig Scharton, from the City of Fresno, has been preaching from the day I met him on a brisk morning back in 2009. Craig gave me my first tour of the Fulton Mall and invited me into a discussion about where the downtown area should be heading.  I for one am very excited that the City of Fresno gets it! Fresno seems to understand where to start researching our past mistakes and how far back to look in an effort to make right the mistakes of our predecessors in planning to best move downtown revitalization forward.
I have often wondered why, when we live in one of the most productive areas in the country, we don’t have a co-op of growers, craftsmen, winemakers, artist, bakeries and such; much like Seattle’s’ PIKES PLACE market. California’s agricultural abundance includes more than 400 commodities, the state produces nearly half of the U.S. – grown fruits, nuts and vegetables and Fresno County is the nations’ leading agricultural county with nearly 5 billion a year in farm product sales.

When I began looking at this issue it sounded wonderful, almost silver bullet wonderful. Oh, what I would give to have a resource like this in the downtown area. It just seems to logical not to already be in place. Fresno has the agriculture, artisans, craftsman, restaurants, bakers and winemakers; Fresno has the space on the Fulton Mall; The City of Fresno is looking for more anchors for the downtown area.  Will somebody just do this, (not so small project) and give our community a venue to show off all Fresno County has to be proud of? 
“Changing a local economic system starts by changing its most basic industries: agriculture, energy, manufacturing, retail, building and transportation and capital. When these sectors are transformed into localized, sustainable, green- and community-focused industries, the entire economy is transformed.”

Turintogreen Student Design Competition

So, I suppose we should have made a test run at getting our schedules in order before being all State of the Blog on readers, but we're ambitious-- and pretty stinkin' excited to get into the blog groove!  We probably should have waited until after we submitted seven energy action plans for review and submitted our final project reports and billing for our Energy Advisers to Valley Cities (Tom Jordan, if you're reading this--it is coming!).  C'est la vie! 

Here's what happened: I bungled the auto-scheduling for Money Monday, got Tuesday's post on green lawn care up just before midnight on Tuesday (it counts), missed Wellness Wednesday, and now Believe it or Not is going to come out on Friday.  Humph.  Progress is slow, but I'm in it for the long haul. I hope you are too.  

Thank goodness Dee was on top of the situation and had her Friday post in early so we can at least claim 4 out of five posts! 

As I’m going through my email looking for inspiration for a blog post, I came across information about a new student competition. What excited me about this particular competition is that it challenges young people to think outside the box. It is a multidiscipline competition that seeks to “transform or even replace the current models of urban management, life and development”. Students from disciplines like Architecture, Interior Design, Landscape Architecture, Engineering, Horticulture, and Urban Planning are invited to addresses issues of overcrowding, food supply, renewable resources, climate and social changes; while coping with global economic cycles. This could be a game changer for the vast majority of the earth’s population. 

Many Americans have no idea how it feels to live in a developing country where the infrastructure and housing needs are astronomical. Where drinkable tap water and a functional waste management system are only stories they have heard of but never seen. While doing my Graduate research I was able to spend a considerable amount of time in Nepal. Kathmandu Valley is one of the most beautiful places on earth; however, it has seen such an invasive amount of population growth that the area cannot sustain its population of 2.51 million.  With a population increase of 60.93% over the past 10 years bringing the density to 4408/sq km (one km is equivalent to 0.621371190 miles), that would make it roughly 6083/sq mile, can you imagine? 

Now you can understand why I’m so up in arms excited about this competition.

According to the competition website the deadline for submissions is December 21, 2012. That doesn’t give a whole lot of time, so students get busy! Oh, and the prize is 150 days in Italy with a daily stipend, the ability to work with some of the most influential architects, planners, engineers and designers on the planet; all working to bring your design into fruition, and as an added bonus, your ideas also get published. That would be enough to motivate me, talk about instant recognition on a global scale.

Okay, so enough of me preaching to the choir, if you’re a student or a prior student that graduated since 01/01/11 or know a student within these disciplines, please forward the link and help them change lives for so many people while jump-starting their careers. 


Healthy Air Lawn Care

Our friends over at the San Joaquin Valley Air Pollution Control District have heard more than an earful about my disdain for modern lawn care.  The fumes from gas powered mowers and edgers, the early morning groan of blowers as they run through my neighborhood ever Thursday.  I cant stand it.  Although I sometimes come off sounding a little hysterical, so its nice to know that there are those out there fighting what I consider the most noble of fights: alternative and healthy yard maintenance!  Dee did some poking around and found a source close to home and shared what she learned.  

Coverage of a particular business is for informational purposes and should not be considered a recommendation or endorsement by the SJVCEO.

According to Doug Ambrose of Healthy Air Lawn Care, there is an alternative to traditional lawn care. I am pleased to see entrepreneurs in the Valley acknowledging the issue of poor air quality and putting forth efforts to make a difference. In speaking with Doug it is very apparent he has an infectious passion for what he does, as he shared some fun facts about green house gas emissions and your typical gas powered lawn equipment. (Which you can find on his web site I am not really surprised at the vast amounts of air pollutants that are introduced into our valley air via lawn equipment; what did astound me was the idea that more gallons of gas are spilled each year while refueling lawn and garden equipment than was spilled by the Exxon Valdez disaster. Where does it all go? Ground water reservoirs and then back into the water distribution network. That opens a whole new can of worms I just don’t have the heart to dive into today.  Give Doug a call and get infected with his passion for air quality and healthy lawn care.

Money Monday: Green Banks

Well, sometimes you schedule a blog post for 6:00 a.m.  and then you spend all morning wondering why there is no post.  Then you realize in the haze of birthday cake that you scheduled for the wrong day.  Darn!

Here is Dee's first Money Monday post on Green Banks that you were supposed to get this morning.  Sorry!  -Courtney

I’ve heard of a Piggy bank and I’ve heard of breaking the bank, but have you ever heard of the concept of a Green Bank? Well, according to the Clean Energy Finance Center, the development of state-level “greenbanks” are one of the most promising emerging ideas in clean energy financing.

Apparently, this quasi-governmental organization brings together public and private sector capital to finance energy efficiency, small-scale renewable energy, and other clean energy projects. Federal loans and loan guarantees are critical for all three clean energy sources (wind, solar and nuclear projects). Building efficiency improvements unlikely to accelerate without federal financing support is fueling a unique financing mechanism.
A principal aim of the green bank would be purchasing old coal plants from utilities and generators, and then scrapping them. The coalition estimates that 100,000 megawatts of coal plants could be retired in this way, opening room for investments in new clean energy generation.

Limited public sector capital is the main advantage of a green bank which uses public capital to leverage private sector investment. In June 2011 Connecticut passed a landmark energy bill that included the establishment of the first green bank in the country called Clean Energy Finance and Investment Authority (CEFIA). The CEFIA will be able to borrow money and aggregate new and existing capital sources, and will have the flexibility to fund many clean energy project types, including electric and natural gas vehicle infrastructure, electricity storage, renewable energy, and energy efficiency.

Aimed at providing low-cost financing for clean energy and efficiency projects the new entity offers Washington and other states a workable model for promoting investment in clean energy at a time of growing concern about the serious finance problems surrounding clean energy deployment.

CEFIA framework demonstrates how a green bank can combine several existing sources of funding without impacting the state budget. The Rockefeller Brothers Fund is helping to finance the development of CEFIA financing programs. If done right, CEFIA will serve as a model for green banks that can be applied to other states.

Xenon: The Next Big Thing?

In late July the SJVCEO began looking for a new employee to fill the hole that Mike Nemeth left (because no one could ever really replace Mike), and part of the application process included a blog sample on one of five predetermined topics.  Originally, I thought we would share all of the blogs from the top candidates, but six out of seven submissions addressed "Xenon: the next big thing?".

Given those results I thought we would just share with you the blog by the newest member of team SJVCEO, Dee Cox!  
P.S. David Boldt, this topic was chosen just for you! 

Is xenon lighting destined to replace halogen lighting the way halogen lighting bullied incandescent lighting off the market? Some would say yes.  

The most famous xenon of all?  The beam of the Luxor  is currently powered by 39 Xenon lamps operating at 7 kilowatts each at an hourly operating cost of $53 (lamps, repairs, and electricity costs)
Xenon bulbs have advantages over traditional vacuum lamps--or those filled with argon or krypton--offerings suppressed tungsten evaporation, which results in a cleaner and longer burn with less blackening.  The bulbs also burn with a brighter, whiter light due to the higher filament temperature for improved contrast rations and an attractive, sparkling appearance. In addition to all of this, the lamps last up to three times as long with a continuous light output for typically 30 percent more luminous flux.  Compared to the argon filled lamps, xenon bulbs wall temperature is 30 degrees Celsius lower, which can have significant implications when the devices are in close proximity to materials such as plastics or wood.  

But what is a xenon bulb, and how is it different from the less expensive bulb that people use everyday? 

If you have ever been to a movie theater, chances are you have seen a xenon bulb at work.  Most film projectors use it because of its incredible brightness. The xenon bulb is also becoming the it light on roads.  You may have noticed its bright, blue-ish list as a car passed you on the highway.  Automotive parts stores market this bright headlight to car enthusiasts in search of an after-market part that will give their car a distinctive style.  

Over the past few years the use of xenon light sources has become increasingly popular, especially in the home.  Xenon light bulbs are being used in numerous ways.  The primary reason is that xenon bulbs have an incredible lifespan--anywhere from 8,000-20,000 hours!  It doesn't hurt that xenon light bulbs operate cooler than halogen light bulbs which can become extremely hot.  Not to worry those of you interested in mood lighting, xenon lights are also dim-able, which can help increase the bulb lifespan.  

The uses of xenon lighting are far-reaching and a bit futuristic to absorb in one setting.  A new range of xenon filled wedge based lamps has been designed for use in a variety of applications from the automotive industry and beyond.  Some even say that xenon technology will enable solar to be more affordable. Imagine walking in to your local hardware store and picking up enough solar panels (equipped with xenon technology) to power your home for 40 years, for less than $2,500? I can see customers lining up for that one! 

I can think of many other ways that xenon lighting could be useful. 

Imagine the farmer working at night; the lighting could help with plowing and cultivation  where a close color match between soil and conventional light can make it hard to pick out detail.

How about flash photography--most of our mobile phones already use this type of flash. And strobe lights!  Oh, better yet, how about bacterial lamps!  The list goes on.  

First, lets consider the way the xenon units "strike up": on flipping the switch the internal beam is an unearthly clear blue, which quickly strengthens and brightens.  The true light is white and cold, like the fullest of full moons; and even though your eyes soon adjust to that, the field still seems to be lit by hidden florescent tubes.  And the spread?  Lamp-for-lamp research shows xenon always reaches further than halogens, with a third more distance covered.  Impressive! 

So, here's the kicker...they don't come cheap.  One really must be careful when switching out halogen to xenon. Do your due diligence and price compare not just the initial cost, but the life-cycle cost of the unit: with the performance and longevity of xenon you can decrease the number of bulbs needed to light a space, further contributing to the long-term cost savings. 

In short, the differences between xenon and halogen lamps are "real and they're spectacular!" <---unintentional Seinfeld reference on the first blog--not bad!
