One Block Off the Grid goes national.

Monday, July 25th, 2011

I have written about One Block Off the Grid before.  I am a big fan of this group.  I was thrilled to get this email yesterday.

 

I’m so thrilled to let you know that One Block Off the Grid has launched 2,170 new solar group discounts in 34 new states.

Check out the map: http://1bog.org/nation

The way it works is that whenever enough residents in a county sign up on the One Block Off the Grid website, all county residents gain access to One Block Off the Grid’s group pricing. As always, our services are free and no obligation.

If you like the pricing, you can choose to be connected with One Block Off the Grid’s trusted local solar installation partner in the area for a free on-site roof evaluation. If you eventually decide to go solar with that installer, One Block Off the Grid gives you a $500 cash rebate. This special rebate is available until October 18, 2011.

We’re also really pleased to announce that we’ll be donating any remaining profits to Kiva City, the brand new U.S. based arm of Kiva.org’s microlending platform. The fund provides microloans to U.S. small business owners in the United States’ most economically challenged cities.

Robert, I do want to let you know that although solar group pricing is great, unfortunately OH isn’t yet doing all it can to make solar affordable for homeowners. While states like New Jersey have a thriving solar market due to strong incentives, your state isn’t there yet. Unfortunately, this means that renewable energy companies may not be giving OH a passing glance when they’re deciding where to expand.

So, when you’re checking out the group deal in your county, be sure to note OH’s letter grade for solar policy, too. We’ve included your governor’s telephone number there and recommend you give him or her a call to say, “I support stronger clean energy policy in OH.”

Together, we can become a powerful force for economic renewal in the United States.

Using waste heat to fill the bath: desalination in Abu Dhabi

Thursday, July 7th, 2011

A while back, my friend Jeff Hershberger sent me a link to a really interesting article.  Apparently, in Abu Dhabi, they have little water, but lots of heat.  Who would have guessed?  situated on the Persian Gulf, this country has plenty of fossil fuels, and therefore cash.  They have spent much of it developing cool architecture, and increasing energy efficiency.  Now they have figured out how to use heat loss in natural gas to desalinate sea water.  A cool applications for heat loss.  As the author states, one that we may soon see coming to America.  It would go a long way to meet the needs of California.  Check out this cool article here:

Save energy with new shades…

Wednesday, July 6th, 2011

This is a product that is genius in its simplicity.  I was first turned on to these shades by a friend of mine.  So here is the basic gist.  Lovely roman shades that are insulated to cut down on heating costs.  Thin enough to be attractive, insulated enough to be high performance.  That is it.  Custom made, so they fit your windows perfectly.   Made from a product known as Thinsulate, a product common in sporting goods (think winter coats for skiers, etc) so it is sure to insulate well without being too bulky.  They stay sealed to window with a small track, and this cuts down on drafts.

According to their website:

HeatSaver® provides Nine Times the insulation of Single Glazed Windows. Four
Times
 the insulation of both Double Glazed and High Performance Windows.

They come in a variety of fabric choices.  These seem like a great investment.  They sent me a pdf of testimonials, so someone seems happy with them.  I think about the fact that we live in Cleveland.  Like many others, our house is old and has drafty windows.  Being a Victorian, the main floor windows are six feet tall and 2 1/2 feet wide.  In order to replace the windows with more energy efficient ones, they need to be wood framed to stay in keeping with the home’s architectural style.  Cost is a huge factor here.  I learned a couple of years ago, that by hanging new drapes that were heavier we were able to keep more UV summer heat and more cold drafty winter air out.  A product like this that seems to be more insulative and seas closer to the casing might be exactly what we need to cut down on those winter heating costs.

I know it is hard to think about winter gas bills in 80 degree July, but now is the best time to get going on a project that will same you big bucks in energy costs over time.  I am told there is a tax deduction for home installation as well as a break for commercial applications.  Summer cooling costs are not cheap around here with increases in utilities.  Check out the Heat Saver Thermal Shades website.

For my fellow geeks, here is some sciency stuff:

 

Test Data for HeatSaver® Thermal Shades
At the end of February 2011 a HeatSaver® Thermal Shade specimen underwent clinical
testing at the Architectural Testing facility in St. Paul, MN. The sample shade used
consisted of a Thinsulate® C150 core with layers of 1/2 mil aluminized mylar on either
side, finished with standard cotton polyester lining and 300 denier nylon. The tests,
NFRC 102-2010, are the most recent - and stringent - industry standard.
The glazed unit measured 47 1/4” wide x 59” tall (1200mm x 1499mm) and consisted of
2 layers of 1/8” DS Clear with a 1/4” dead air space, wrapped with an aluminum frame.
Thus it closely replicated a window configuration common from the 1960s onward.
Base Window Test Date: ! ! ! 02/22/11
Base with Attachment Test Date:! ! 02/23/11
Report Date:!! ! ! ! 03/23/11
Test Procedure: U-factor tests were performed in a Guarded Hot Box in accordance
with NFRC 102-2010, Test Procedure for Measuring the Steady-State Thermal
Transmittance of Fenestration Systems.
The average metering indoor air temperature established was 70.41 F. The average
cold side air temperature was -0.10 with a side wind velocity of 14.56 mph.
Test Duration - Base Window:
1. The test parameters for the base unit were considered stable for two consecutive four
hour periods on 02/21/11 and 02/22/11.
2. The thermal test results were derived over a four hour period on 02/22/11.
Test Duration - Base with Attachment:
1. The test parameters were considered stable for two consecutive four hour periods on
02/22/11 and 02/23/11.
2. The thermal performance test results were derived over a four hour period on
02/23/11.
Results
1. Thermal Transmittance of Test Specimen (Us)! ! 0.82 0.27 Btu/hr•ft2•F
2. Standardized Thermal Transmittance of Test Specimen (Ust) 0.75 0.26 Btu/hr•ft2•F
The reported Standardized Thermal Transmittance (Ust) was determined using CTS
Method, per Section 8.2(A) of NFRC 102.
Test Results Summary:
Standardized U-factor (Ust) - Base Window: ! ! ! 0.75 Btu/hr·ft2·F! CTS Method
Standardized U-factor (Ust) - Base with Attachment: !! 0.26 Btu/hr·ft2·F CTS Method

Conclusions:
The U Factor of 0.26 listed above equals an R-Value of 3.85. Hence we extrapolate the
following.
! ! 1.87 Dbl. Glazed Window!! 0.86 Single Glazed Window
! ! 0.68!! Air film! ! ! ! 0.68
! ! 2.00!! Dead Air Space! ! 2.00
+ 3.85!! HeatSaver®! ! + 3.85
8.40 Total R-Values 7.39
! ! 0.11 U-Factors! ! 0.13
The additional values listed are established through ColoradoENERGY.org research
and accepted standards. The dead air space between the shades and the glass will
equal approximately 1 per inch, up to 2 inches after which a convection cycle would
negate further gains. Gains or losses due to air infiltration have not been factored in.
* The test method above does not include procedures to determine the heat flow due to either air
movement through the specimen or solar radiation effects. As a consequence, the thermal transmittance
results obtained do not reflect performances which may be expected from field installations due to not
accounting for solar radiation, air leakage effects, and the thermal bridge effects that may occur due to
the specific design and construction of the fenestration system opening. Therefore, it should be
recognized that the thermal transmittance results obtained from this test method are for ideal laboratory
conditions and should only be used for fenestration product comparisons and as input to thermal
performance analyses which also include solar, air leakage and thermal bridge effects.

Now is a great time to switch, to CFL’s

Sunday, July 3rd, 2011

I was at the local Discount Drug Mart the other day.  Something about this store is familiar, no matter when I go in.  It is one of the few remaining places on earth where you can get sewing goods, canning supplies, groceries, drug store items, and RIT dye.  So, as I am cruising to the check out, I spied an entire endcap of CFL bulbs.  These two packs were on sale for $1!  That’s just 50 cents a bulb folks.  Using 75% less electricity than a conventional bulb, with little or no heat, this is a no brainer.  I bought my limit of 3, even though I have a stock of them, because you cannot beat that price.

Upon closer inspection, I found these were bulbs from First Energy and it’s energy efficiency efforts.  This was a public relations nightmare, regardless of the intentions.  Apparently, we have a great loophole in our utilities laws.  Rate increases have to be overseen and approved by the state.  This keeps electric companies from strangle holding you with your electric bill.  The loophole, though, is that you are paying for the energy separate from the cost to get the energy to you.  The law allows utilities to raise rates to pay for loss of income from delivery fees when you use less energy.  So, saving energy saves you less dollars than it should.  So, when First Energy had to meet a mandated efficiency program, they decided to buy 3.25 million CFL bulbs and distribute them to their customers.  They then raised the rates (I believe of just the delivery fees) to cover the costs.  I call shenanigans on this type of lawmaking which allows utility companies to get around the laws that were put in place to protect consumers.  Just as when cable companies were regulated, rather than raise rates, they made more channels premium to make you pay more per month.

I don’t know all the details of the First Energy mess, but apparently the Ohio governor had to get involved in the whole debacle.  In the end, rather than hand delivering all these bulbs to individual First Energy (and it’s subsidiaries) customers, many ended up on the shelves at Marc’s, Discount Drug Mart, even Goodwill.  All I know, is that I got my 6 bulbs, and I am set.  Of course, I switched nearly every bulb in my house out to CFL’s a couple of years back and I have only had a single one burn out.   I never miss the chance to take home a free bulb from Earth Day events, trade shows and the like.  I will likely be set for the next decade! Now is a great time to star decreasing your electricity usage and get in on this great deal!

Customer Choice for Electricity and Natural Gas

Friday, January 7th, 2011

It’s hard to believe you can reduce your cost of electricity or natural gas with the stroke of a pen…but it’s absolutely true.  Here is what you need to know about getting the most out of customer choice utility programs. These programs have been available in most industrialized states since 1999.  The idea is to introduce competition between electricity and natural gas utilities in an otherwise monopolistic business environment. Even after you start buying energy from an alternate utility your local utility continues to provide distribution and other services without change.  This is because they charge separately for these services.  Just take a look at your utility bill and see the many separate charges.

You can buy electricity or natural gas directly from an alternate utility or you can buy from an agent who represents many alternate utilities.  I recommend the latter.  Here is why.  An independent agency is constantly monitoring the fluctuating energy prices and knows on any given day which alternate utility is offering the best deal.  An agent can make sure you are placed with a utility that does not have an early termination fee giving you the flexibility to switch to a different program when market conditions or the competitive landscape changes. The point here is that each utility has its own unique pricing.  I recently switched a new single store customer of mine from one alternate utility to another alternate utility and dropped his price of natural gas by 21%.

Lastly, you should know that food retailers are highly desirable electric utility customers because of the large amount of energy used but more importantly the consistent pace of energy use stemming from refrigeration and lighting.  The latter means utilities won’t need to maintain as much extra generating capacity and distribution infrastructure like they do for customers who use a lot of energy once in a while.  If you have multiple locations, have your agent solicit custom bids from several alternate companies based on your total usage.  Customers who use lots of energy at a consistent pace are often granted the lowest rates…but only if you negotiate for them.

This is a guest post by Bob Savage.  Mr. Savage is an Account Manager at Supermarket Energy Technologies, which has been manufacturing energy efficiency products for food retailers and OEMs since 1996. They have a suite of energy efficiency solutions which can significantly reduce operating costs.

7 billion and counting…

Monday, January 3rd, 2011

I have to give a shout out to Joe.My.God for sharing this video.  It really got me thinking…

There are a lot of statistics in this video, and some made me ponder more heavily than others.  The one that startled me the most was the increase of population in the last decade and the projections for mid century.  We added a billion people in the last decade or so, and can expect to add another 2 billion by 2045.  That is a pretty heavy duty prediction.

We already know that we are using the planets resources at a rate that is not sustainable.  If we continue at the current rate, we will see our supplies of minerals, water and oil depleted far faster than most people realize.  If we are seeing the current electrical grid and use of power as tight as it is now, imagine the stress on the system when you add a 25-30% increase in the use of those resources.  If we cannot manage our oil and fossil fuel consumption now, what will we do with an extra 87 million people to worry about?

We are also moving from an agrarian society to an urban one.  For the first time, we now have more people living in cities than in rural areas.  We have seen an increase in megacities, that is cities with over 10 million people.  In 1975, there were only 3 of these enormous urban environments, but now we have 21.  In this video, they estimate that in 40 years, 70% of us will live in these mega cities.  Reflecting on these numbers brings up the importance of dense urban growth, and the importance of building smartly to accommodate these huge population increases in our cities.  Cities that do not embrace new technologies and new planning ideas could suffer greatly in the coming decades.  In America specifically, we do not have a power grid that can support a huge increase in populated areas.  Not only are we going to have to find a way to produce more power, but also to manage it more efficiently.  If cities like Los Angeles experience problems with pollution now, how will they remain livable while they add another 2 million or so people?  While issues like these will affect everyone, these mega cities are going to feel the pinch more than most.  Then there is the issue of food production.  Much like the growth of the urban environment during the industrial revolution, efficient food production and transportation is going to be a huge concern.  As we have to go farther and farther from the urban core to produce food, the cost to produce and transport it will go up.  Furthermore, the quality of produce will continue to diminish as we prepare for more of our food to come from mega corporate farms.

In the US, there is the concern of our crumbling infrastructure.  Currently, our electrical grid is in danger.  Bridges, water delivery systems, sewers, dams and more are in trouble.  We can currently only afford to repair and replace our infrastructure as it falls apart.  Look no farther than Cleveland’s own I-90 bridge and our postponing of its replacement for years to see the proof.  We are patching it to make it safe, but it is long overdue for replacement.  Minneapolis and Seattle have seen major bridge failures in the last couple of decades.  Sludge dams from coal mining are failing in some areas.  Levies in need of replacement may have been the biggest cause of Damage in New Orleans.  If we are seeing this stress on the infrastructure now, imagine when we add a 20% increase in population.  If California is searching for places as far away as the Great Lakes today, what will they do in 40 years?

5% of us use 23% of the energy produced in the world.  13% of the population does not have access to reliable clean drinking water.  38% lack adequate sanitation.  If we have failed to solve these issues for a population of 7 billion, how can we expect to solve it for 9 billion?  Then there are the issues of food shortages, natural disasters, climate change, they only get bigger and worse if do nothing to solve them now.

And just to make you aware, China has a one child policy for urban areas.  A large portion of the country is limited to having only one child per couple.  Over the years, they have become more lax on this policy.  Some imagine this policy will go away in the next decade.  If it does, what will that do to the overall planet overpopulation?

10 tips for living greener in the modern age…

Wednesday, September 1st, 2010

This world is a fast moving place these days.  Modern convenience and throw away society has made it easy to do almost anything, find anything, consume anything.  But all of this technology and convenience comes with a hefty price tag: depleting ozone, greenhouse gases, burgeoning landfills, disappearing resources, and the wars and negotiations that we conduct to preserve this wonderful way of life.  But just because you want to live lighter on the earth doesn’t mean that you have to buy an yurt and move to the wilderness or join an ashram in the Himalayas.  There are plenty of ways to live a modern life, with its conveniences, and still reduce your impact on the planet.  Here are some ideas to get you started:

1. Turn off the lights.  Simple, but effective.  Turning off the lights when you are not in the room means less kilowatt hours of energy that you will be using in general.  This concept goes to more than just the lights, though.  Turn off your television if you are leaving the room.  Don’t leave your TV or radio on for your pets while you are at work ( they really don’t want to listen to it anyhow).  Just be mindful of obvious waste of electricity.  Look for ways that you waste energy and try to find ways to reduce it.  Buy a night light instead of leaving the bathroom light on at night,for example.

2. Buy larger packages. While the convenience of individually wrapped items is great for kids lunches and the like, they come with a lot of extra packaging.  The 6 pack of individual applesauce cups has a tone of packaging that will likely not be recycled, vs the large jar that has 3 times the amount.  The cost savings of buying in larger packing will allow you to invest in reusable containers to put in those lunch bags.  For that matter, think about the throw away stuff that you get everyday.  Take your own mug for that morning coffee, use reusable bags for your groceries, buy in bulk when you can.  We are nearing two years of plastic bag reduction and I have only brought home one plastic bag in that time.  All without any inconvenience to me.

3. Buy only what you need. This is a biggie for me.  Most American households throw away nearly 500 pounds of food every year.  This can take a definite change of habit, but once it becomes a regular thing, you will find it easy to maintain and will save you money.  You will need to plan better, create shopping lists and stick to them, and buy perishables in easily usable quantities.  After shopping, you may need to break down larger packages and freeze some of your food.  Use your freezer as a way to prolong the life of food for short periods, not long term, as this will lead to less food surprises in the back of the box and less food wasted to freezer burn.  When it comes to things other than food, buy what you need and invest in better products that will last longer.  The more use you get out of products, the more money you will save and a better use is made of the energy put into making them. That $3 T-shirt is not such a bargain if it lasts only one wearing…

4. Drive less.  Walk more. Simple enough, but harder to do.  Plan ahead, combine trips, and use your legs and bicycle.  Take the first spot you see in a parking lot and walk a little more, rather than driving around or idling while you wait for that spot nearer the door.  The exercise will do you good.  If you are going to a strip mall, park once and walk between stops.  Don’t get in your car and drive to the other store that is 100 yards away.  Try to do more in your own neighborhood where you can get to by foot-at least when the weather is nice.

5. Recycle. Even if you don’t have curbside recycling, you can drop your plastic bags off at the store, your cans and bottles at a local spot, and many schools and churches take paper to recycle for extra funds.  But it really goes farther than that.  Try to buy products that use recycled content (or else why bother recycling?) and that use reduced packaging.  Furthermore, think about what the packaging is:  aluminum cans are likely recycled and back on the shelf in 60-90 days-shoos it over glass or plastic;  steel is heavily recycled due to casts and most steel used at all has at least 25% recycled content already; glass bottles are more heavily recycled than plastic; paper is a commodity that is easily recycled-a paper box is better than a plastic container if you are not going to reuse it.

6. Reuse. Simple.  Try to reuse anything that you can at least one time before throwing it out.  That plastic zipped bag that your food came it can easily be rinsed and reused instead of popping out a new Ziploc.  If something comes in a plastic tub, then will work jsut as well as Tupperware.

7. Avoid specialty use items. Why in the world does anyone need a special brush that is just for putting butter on corn when a knife will work just as well.  The more specialized a product, the less use it will get and the more resources are wasted in its creation.  We have been eating corn on the cob for plenty of years without those special little prong holder things to hold the ears with.  Don’t get me wrong, some items have a definite purpose, but most of us don’t need the tools of a butcher or pastry chef, no matter how much we think of our own cooking.

8. Print less. One of the joys of the modern era is the ability to share things digitally.  Use technology to your advantage and print things less often.

9. Buy Energy Star. When buying a new appliance always try to buy Energy Star rated appliances.  Yes, they will likely cost you a little bit more, but the energy savings will pay for itself in no time.  Look for rebates in your area for Energy Star.  While in Seattle, my mother had to buy a new refrigerator.  By buying Energy Star, she was able to receive 10% off at the store, get a state rebate, get a local utility company rebate, and she had it recycled for an additional rebate.  It was actually cheaper to buy Energy Star, before even turning it on.

10. Turn things off at the source when  not in use. Many appliances suck up energy even when you are not using them.  We have a big TV, but we use a master strip to cut the power when we are not watching it.  Same with the DVD player, VCR, etc.  It is estimated that over their lifespan, most appliance use 75 % of the energy that they use when they are not in use.  Same goes for portable devices: cell phone chargers draw power even when they are not charging anything, and cell phone batteries will last longer if they are not overcharged.  Timers and the like are for more than just heating.  Make sure that your computer is set to go into stand by mode after a set period.  This means that you can easily reduce the energy you use without having to remember to power it down.

Clyde gets gassy…

Saturday, August 28th, 2010

Cleveland is not the only city in Ohio that is turning to greener technologies to make a difference in their communities.  Clyde, a small town near Sandusky, is looking at joining the ranks of other towns in northwest Ohio to create cleaner and greener energy.  This time, however, they are not turning to solar power like so many of their neighbors.  They are looking at turning trash into energy.  From the News-Messenger website:

The idea is to build a traditional recycling center and an industrial-sized pyrolyzer. The pyrolyzer will take trash and heat it in the absence of oxygen to create pyro-gas, which is similar to natural gas. The pyro-gas will be used to run engines that power turbines to create electricity…

Some advantages of pyrolysis include eliminating future landfill methane by diverting waste and controlling ground and surface water pollution. It also has a closed loop design, which means the gases burn completely during electricity generation. It also discourages pathogens and rodents that would be in a landfill, the company said.

This is similar to the model that is being planned for the Cleveland area.  I am not a fan of landfills, so anything to turn trash into something else makes me happy.  Besides, the facility would increase recycling and turn the current hand sort method into an automated plant.  This builds capacity and makes recycling across the region easier to maintain and support.  It would lower local energy costs for local residents as well.

You go Clyde!

What do YOUR appliances cost?

Wednesday, June 23rd, 2010

I live my life on a master strip.  When we leave a room, nearly everything goes off these days.  On our electric bill is a graph that shows what our electric usage is compared to the same month in the previous year.  So, after a year of this behavior, I am pleased to be seeing a significant drop in our monthly usage.  It is said that as much as 75% of the average power used by an appliance is used while the unit is off.  So, not only are we saving on power, we hopefully are prolonging the life of the appliances.  While cruising the web, I was alerted to an interesting interactive application by Mashable.com.  It is an application that tells you how much energy an assortment of appliances, light bulbs, etc use.  You can see how many watts or even how much in dollars each uses-by state.  It is a great application and will help show you how much money/energy you can save by switching to Energy Star.  You can even turn all of them off and only turn on the ones that you are using and you can see how much energy your lifestyle takes.  Check it out on the GE website.
