I follow the folks that write Japan Safety: Nuclear Energy Updates and they just posted an article from the Japan Times where they look at the current government’s plans for energy sustainability over the next few decades. The picture is disturbing in light of the disaster at Fukushima in 2011.
Nuclear energy is carbon neutral, but it brings so many other long-term risks into the picture that it should not be considered as a sustainable energy source. At Fukushima, they are having to store huge amounts of contaminated water on a site that was completely inundated with ocean water in 2011.
I have thought a lot about the vocabulary we use when we speak about issues. Much of the language we use comes to us courtesy of Economists. We speak of consumers or clients rather than citizens. We speak of economic debt and deficit to the exclusion of the discussion of social, cultural, environmental or infrastructure debt and deficits. We speak of healthy economies rather than healthy people, or healthy environments. And we rarely ever focus on important issues like fun or happiness.
This vocabulary poses a number of real problems for us. One very real problem is that if we use economic terms to describe our problems, the solutions we find will be limited to those that offer economic value. This is the old problem where having only a hammer in your tool belt tends to make every problem look like a nail. In the long-term, if we are to really deal with important issues in a constructive way, we have to change the way we speak to reflect our real values. This type of culture change takes time, and, if science is to be believed, we don’t have a lot of time before the chaos starts.
In the meantime, we can at least frame our economic arguments in terms that demonstrate that sustainability is at the heart of long-term economic success, and that is done brilliantly in a TED talk (embedded below) by Chris McKnett from 2013.
Have you ever heard of the concept of an “Earthship“? I was introduced to the concept by my brother-in-law about 14 years ago and was blown away. What is an Earthship then? In a nutshell, an Earthship is an Eco-friendly home, made predominantly from recycled materials, designed to be as close to “off-grid” as possible.
The concept of Earthships arose in the halcyon flower-power days of the 1970s in various states in the southern USA. The concept seems to have developed by Michael Reynolds, an architect from New Mexico. As you can see in the linked Wikipedia article, his idea was not without problems, but it was, none-the-less revolutionary. Michael has a website where he educates about, demonstrates and promotes the Earthship technology. The site has designs for a number of systems that an Earthship needs if it is to meet code (see figure 2, below). Continue reading What the heck is an Earthship? … maybe an idea whose time has come!→
One of my colleagues at work sent me this list of ten interesting environmentally-related web-pages. He recommended them to me and suggested I take a look at them. You may wish to take a look at them too. Thanks Phil!
For 50 years, WWF has been protecting the future of nature.
The world’s leading conservation organization, WWF works in 100 countries and is supported by 1.2 million members in the United States and close to 5 million globally. WWF’s unique way of working combines global reach with a foundation in science, involves action at every level from local to global, and ensures the delivery of innovative solutions that meet the needs of both people and nature Continue reading Some links to interesting environmental sites→
One of my colleagues showed me this site today and it looks really good. This is a link to their blog page. This group has some pretty high priced help on their roster. From Harrison Ford to Hillary Clinton, they seem to have the bases covered.
One of the environmental movement needs more of is “good news stories” and this blog is replete with them. One that immediately attracted my attention is on a new initiative to stop poaching of African elephants. The article includes a video on the subject with the aforementioned celebrities. Worth a read. Don’t forget to bookmark the page.
It may be an advertising pitch, but there is some truth to it. The Rainforest Alliance has put together a cute pitch that TED.COM has nominated as one of the 10 best ads of the year. The ad shows you what you don’t want to do to be green, and then goes on to show you one thing that you can do to make a difference. The advertisement is to “Follow the frog” which refers to purchasing goods that bear the Rainforest Alliance’s frog logo which indicates that the product was made in a way that meets the certification standards set out by the group.
Rainforest Alliance is a non-profit with the mission to “… works to conserve biodiversity and ensure sustainable livelihoods by transforming land-use practices, business practices and consumer behavior.”
Now, you may note that this approach runs counter to the approach promoted by the “Story of change” people but I think the green movement is probably large enough to embrace more than one strategy for saving this beautiful world.
Why not visit their site or just watch the ad here:
This is a follow-on article to Mike Biddle’s excellent video on new ways of dealing with plastics recycling. In this article (originally published on the TED.COM website, Mike responds to a number of questions that arose from his original TED talk. He deals with the thorny issue of getting the waste to one of the “mining” facilities.
The TEDtalk elicited over 1000 comments and questions on TED.com, Youtube, Facebook, Twitter and elsewhere, including direct emails to Biddle and to the TED staff. Faced with the impossibility to answer them individually, Mike has grouped them together and addressed them below.
And now over to Biddle…
I want to thank the TED community for all of the heartfelt comments and great questions. Although many of the comments were directed to me as I am the one that gave the TEDtalk, I’m replying here on behalf of the whole MBA Polymers team. Much like the saying “it takes a village to raise a child”, it…
This video is all about empowerment. It is all about acting on our commitments…to the environment, to social justice, to each other. It is about supporting our government’s initiatives for becoming a “World Class Regulator“.
As with other “stuff” video, this one makes its point in the same clear logical fashion, taking us from being environmentally conscious but isolated islands to empowered actors in a movement to make a better world for us all. It does it using the same cheeky style, replete with stick figure art and snappy dialog.
Here is an unusual article from CBC about how Amazon.com is making use of Japanese goats to get rid of problem weeds on the company’s Japanese office grounds. Companies don’t always get it right, but when they do, they should get kudos from the rest of us.
Oh, and by the way, goats and sheep aren’t allergic to poison ivy, so they are a great way to get rid of that particularly pesky weed. See this interesting page describing how goats can be very eco-friendly. I am not certain how eco-friendly goats are in times of drought though…I had heard that the very things that make goats eco-friendly from a herbicide perspective can make them less sustainable in times of drought because they tend to denude the landscape, even eating the roots of the plants.
Once again, TED has published a very timely piece on an issue that is becoming huge in the west these days…corruption and its societal costs. Corruption has always been around, but until recently in the west, it was associated with shame and scandal. Now it seems to be so commonplace that we barely even acknowledge it. But the costs of corruption to society are very important and this TEDGlobal talk puts the matter into perspective. definitely worth a read. Thanks TED.
When we talk about corruption, certain types of individuals come to mind, says Charmian Gooch, co-founder of watchdog NGO Global Witness. She gives some familiar examples of the type. There’s the (former) Soviet megalomaniac — such as Saparmurat Niyazov, the all-powerful leader of Turkmenistan, whose indulgences included erecting a 40-foot-high gold-plated statue of himself that rotated to follow the sun. There’s the African minister, dictator or official, such as Teodorin Obiang, son of the president of oil-rich Equatorial Guinea, where many live in dire poverty despite per capita income comparable to Portugal. Obiang junior owns an 18 million Euro art collection, million-dollar sports cars, a Gulfstream jet, and a $30 million Malibu mansion. Until recently, he was officially earning less than $7,000 a month. Then there’s the former Nigerian oil minister Dan Etete — a convicted money launderer.
It’s easy to think of corruption as something that happens “over there,”…
As a follow-on to my earlier article about various technologies for lighting your home, I wanted to post this link. As the date for conversion of all light bulbs from incandescent looms near there is a lot more is being said about the safety of CF bulbs. Scientific American, known as a source of reliable information that is accessible to the common citizen, has written an article that describes the dangers associated with disposal of broken fluorescent bulbs.
Regardless of what anyone tells you, if you live in North America your pool should not be losing more than about an eighth of an inch of water (3 mm) each day in the summer. If it is losing more that that…don’t ignore it and don’t let people tell you that the larger amount of water loss is to be expected. An inch of pool water is a huge amount and the western world is just beginning to understand that water is our most precious resource. Don’t waste it like I did!
My family has had an in-ground swimming pool since the kids were little. Generally, we have only had to fill up the pool in the early spring and we are more-or-less good for the rest of the season. There is a bit of evaporation, but it is usually replaced by rainfall. This year, unfortunately, was “off the charts” as far as water consumption goes and that is an environmental disaster. Continue reading Pool leaks are an environmental disaster!→
The other day at work, one of my colleagues passed a link on to me because she knew that I am interested in waste management. I really have to thank her because the link she provided was to an excellent 3 part article entitled “Trash Troubles – grappling with our garbage” (Metroland.com – Trash Troubles) published in MetroLand.com and authored by Don Campbell and Thana Dharmarajah. These two journalists have done a really good job describing the problems with our solid waste management in many communities in Southern and Eastern Ontario. It is really worth a read.
In the article, they describe the escalating cost of landfill, the ridiculous practice of shipping our garbage out of our jurisdictions, the patchwork of recycling programs across the province and they provide a few ideas about what citizens can do to minimize their impact on the environment. They discuss where the responsibility lies for cleaning up our act.
The most important thing that I took away from their article was a feeling that the province needs to step up to the plate and play a bigger role, establishing policies and standards for managing solid waste across all communities, identifying best practices, building markets for recycled materials, and helping to fund waste management programs in a way that provides the best bang for the buck.
Another thing that they bring up that I have been advocating for years is for extended producer responsibility for waste management. I blogged about this earlier in my open letter to the plastics industry. It is high time that we start holding producers partly responsible for managing the waste that flows from our consumption of their products. Yes, this will increase the costs of products, but we are paying anyway…this will only bring the payment front and centre and not hiding it in the line items of municipal taxes. If you want to read more about plastic recycling read my blog entry at https://gourken.wordpress.com/2011/10/08/an-open-letter-to-the-plastics-industry/.
Anyway, the article by Campbell and Dharmarajah is an excellent overview of the issues that we need to face if we are to manage our solid wastes responsibly. While the picture they paint isn’t too hopeful, they do present a few things that will help us see that the future isn’t too bleak either.
On a final note, I am still very intrigued with Mike Biddle’s idea of using of mining technologies to mine waste streams to allow the extraction and reuse of plastic polymers and metals. If it works, this is a paradigm shift worthy of the word. It seems to me that you could use this technology to go back into landfills and mine for valuable resources (like the plastic polymers and the metal ores buried there). If you want to read more about this technology (and see a video of how it works), visit Mr. Biddle’s web site at http://www.mbapolymers.com/home/.
I am constantly looking for good environmental blogs and have been following a really good one lately named “Environmental world for all”. The site is authored by a university student in peace studies with minor in environmental studies. One of the author’s recent posts discusses the benefits of solar LEDs for use as Christmas lights. It is a really well thougth out article and in it the author discusses the pros and cons around this issue.
When I left a comment and asked him about the ability to recycle these devices he brought my attention to this site (Solar Lights Recycling | Your Solar Link) in the US that is trying to set up a recycling program for these products.
If you are interested in environmental issues I think a few minutes browsing these two sites would be time well spent.
Back in 2009, my family bought a 2010 model year Honda Civic Hybrid. The chart in the dealership, which was produced by an independent tester, gave the Civic a rating of 60 miles per imperial gallon (mpg) in the city and 66 mpg on the highway. A review of the Natural Resources Canada (NRCan) website seems to confirm this rating.
NRCan’s site gives the “mileage” of every car sold in Canada by year. It is supposed to be based on testing that simulates a fuel economy for a car that is driven 20,000 km per year. Presumably the test would simulate real-life conditions including the number of occupants, and a variety of weather and geographical conditions, but it isn’t clear from their web site. The mileage for my car the 2010 Honda Civic Hybrid is given here: http://oee.nrcan.gc.ca/transportation/tools/compare/compare-results.cfm and it confirms the 60/66 rating given at the dealer.
My question is, what drugs were the testers on when they came up with these figures? We have been using the Civic for almost two years now and we have never come close to those figures. I grant you, that the test figures are likely for the “average” driver, but even so, we have rarely got better than 6.1 l/100km. That works out to about 46.3 mpg. This is a far cry from the 63 mpg (combined city and highway) that we were supposed to get.
When I look at the United States government website I their numbers are closer to my results. they show 40 miles per US gallon (mpgUS) city and 45 mpgUS highway which is about 43mpgUS combined. That equates to about 51 miles per imperial gallon (or only 85% of the NRCan mileage estimates) which is getting better, but it still ends up being about 5 mpg high by my experience.
So what are these testers doing. I assume that they must have only a single driver, and that they must be always on a flat road, with no head-wind and they must be accelerating at a snail’s pace. If I want to approximate these ratings, I would need to get an 100 pound driver driving downhill with a tailwind and the car in neutral.
While I never really expected to get 60 mpg, I did expect better than the 43 mpg that we are getting. Am I expecting too much to ask for mileage approximating the promised rating? I don’t think so. I would likely have bought the car anyway, given that I am interested in the environment, but I don’t like being lied to. If the “independent” tests were to be even remotely useful they should be achievable by the majority of the drivers under normal conditions.
Now, I know I have ignored things like the benefits to the environment, but I have also ignored things like the total cost of ownership (maintenance of the batteries over time) and the cradle to grave costs of the car in terms of cost of building, cost of transportation, use by the consumer and cost of disposal.
But when it comes to strictly the way the cars are advertised, where is the truth of the situation? I sure don’t know? I do know that I feel ripped off! What about you?
Sometimes being environmentally friendly means using new technologies like solar and wind power, but sometimes it is simply about doing what we have always done, but doing it in a smarter way.
URISA, an association of GIS professionals, has an annual competition for students in the GIS field to produce papers and posters on using GIS to solve real world problems. One group in Maine has used GIS technology to model how to reduce the cost of transportation of recyclables from collection locations to the processing plants. They will still be using the same technology to collect the recyclables, but they will be reducing the distance that they are transported, resulting in an enormous savings in CO2 generation and a reasonable savings in cost. This will be especially valuable if we ever move to a “mining” paradigm for dealing with recyclable waste.
The paper compares the costs to reduce greenhouse gasses of three different policy choices against the Cap and Trade (CAT) option, which does not subsidize the production of biofuels. They show CAT as the lowest cost alternative in terms of dollars per unit of carbon reduction but find that the higher cost options are frequently adopted. They go on to show that the subsidized options, though more expensive, produce the highest potential for private gain, while CAT produces the highest potential for carbon emission reduction per dollar spent.
While the article does not answer the question posed in the title, it does seem to conclude that if private interests were taken out of the equation, we could get better carbon reduction bang for our bucks if we adopted a cap and trade system rather than any of the subsidized bio-fuel alternatives.
The article is a bit technical, but it is still written in such a way that most informed readers can take something away from it. It is also nice to see that these issues are being discussed by institutions such as MIT.
First, I am not rabidly anti-plastic. I think that plastic has made many parts of our life better, but I am against plastic waste (plastic for which there is no after market recycling program) and I am against over packaging, and your industry is implicated in both.
From an energy perspective, I am aware that lightweight plastic packaging is cheaper to transport than many other materials. From an energy perspective, the problem is that plastics consume oil products that could be used to heat homes, to fuel automobiles, etc. If you cannot reuse a plastic product that is recycled, it means that you will be consuming new oil for every product you produce.
From a waste perspective, you need look no further than the Eastern Pacific to see a Texas sized “island” of plastic waste that will last for tens of thousands of years. If your industry does not come to grips with this problem, we will be doing it for you by banning the use of plastic products. This is not in your best interests and it isn’t good for consumers either. Get your act together and:
1. Make certain that every type of plastic is well-marked for recycling and don’t allow unmarked plastics into the market place.
2. Help local governments fund plastic recycling programs
3. Help create markets for recycled plastic and ways to use them that is environmentally friendly and energy-efficient
4. Don’t produce anything that you cannot re-use in manufacturing and set targets and deadlines for recycling 80% of the product you produce.
5. Ensure that products that contain recycled plastic are marked, advertising that they have helped keep plastic out of landfills.
6. Talk to the packaging industry and retail stores to get them to reduce “over packaging” and to ensure that all packaging can be easily separated into non-plastic and plastic products and that the individual plastic components are all marked for recycling
7. Fund “bring it back collection sites” for large plastic components that it is not possible for the recycling programs to handle.
Many of the same recommendations should be addressed to municipal and provincial governments to ensure that if industry doesn’t step up to the plate that the regulators do, so if you don’t want to get regulated out of business, I suggest you consider cleaning up your act.
As a post script, the article below is about a company that takes all sorts of post consumer plastics and metals and uses a “mining” approach to turning them back into usable plastics – reducing waste, reducing the cost of production and … well, give it a look, he says it better than I could anyway.
I just ran across a wonderful innovationthat seems to have been around for a few years but just now seems to be garnering widespread attention. The innovation seems to be the brainchild either the Massachusetts Institute of Technology or of Mr. Illac Diaz of the Philippines. It is as brilliant in its simplicity as it is as a light bulb. I am going to leave the description of the “bulbs” and how they are used to the foundation (and to two interesting YouTube videos (describing the why and how). One of the linked videos below describes this as an idea out of MIT and that makes sense because that institution seems to focus on a lot of simple projects to help the poor (see my earlier blog about solar powered water desalinators that were developed by MIT folks).
The City of Ottawa has a nice new web page that acknowledges the existence of solar energy, and in particular solar domestic hot water (SDHW). The site, which can be found on ottawa.ca gives information about two different types of SDHW systems: a CSA approved factory packaged system and not factory packaged system. Both types of installation need a building permit.
Both installation types must be installed by a qualified installer (CanSIA certified) but non-factory packaged installations must be certified compliant with CSA F379.1-09 (the reference standard for SDHW) and with the Ontario Building Code by a professional engineer licensed in the Province of Ontario.
This doesn’t sound like a lot of help, but when I had my solar system installed, there were no guidelines or standards available and we had to slog through a morass of bureaucracy to get our installation approved, so that guidance is very welcome.
This information should make the process of installing SDHW more transparent and it should really reduce some of the risks to the homeowners and installers. Good job Ottawa!
I don’t know if you have noticed it too, but there seems to be a lot more power outages and surges these days. I’m not talking about the 20 day variety like the one that hit us during the ice storm, but rather the one and two second ones that seem to come in bunches every few months.
Hydro has a fund to deal with hits to electronic equipment that is damaged due to surges like the one we had in Kanata when a 17 kV line dropped on a 10 kV line early in the last decade and fried a bunch of computers. Fair enough as far as it goes, but what about the things that didn’t burn up? What about the fridge that was supposed to last for 15 years, but ends up only lasting 10 years because it was hit by a large surge? What about the dozens of light bulbs that were supposed to last for 10,000 hours and end up only lasting half that because they experienced a big surge? Sure, they didn’t die when the surge hit, and there is no way to prove that their life span was decreased due to the surge, but doesn’t it make sence that it would be? Where is the compensation for these items?
OK you say, but that is history…old news…almost 10 years old now! What about today? Well, of course, you’re right. There aren’t a bunch of surges like the one I spoke of happening from day-to-day, but there are a whole bunch of little black-outs where the power drops for a few seconds and then surges back on. Aside from the inconvenience of having to re-set every clock in the house, have you never noticed anything funny with your electrical devices after such an outage? I have, and I am not speaking about problems with your computers because, like me, most of you will have shelled out hundreds of dollars to buy surge suppressing power bars or uninterruptible power sources (UPSs) for your high-end computer gear. No, once again, I am speaking about your equally expensive fridges, stoves, and even furnaces, each of which is now controlled by computer.
Every time there is a power outage in my house, the ice maker on my high-end fridge stops working. I have to cycle off the power on the fridge at the circuit breaker, leaving it off for at least a minute (so that any capacitors in the system drain) and then cycle it back on. Only then will the unit come back to life.
Or how about your heat recovery ventilator unit (HRV)? An HRV is critical to the healthy functioning of an R2000 or an energy star home as it keeps the humidity level in the house within reasonable limits). At my house, the same thing happens to my HRV when there is a power outage too. Once again, I have to cycle off the unit, wait, and then cycle it back on again.
To me, it is only reasonable to assume that these expensive devices “feel” these small power outages and surges. Doesn’t it make sense to you too? Well, if they “feel” the pain of the outage/surge combination, doesn’t it seem likely that they experience a shortening of their useful life when it happens? Where is the compensation for this loss of useful life for these expensive products?
The question in my mind is, if Hydro cannot provide more reliable power, shouldn’t they have to come up with some sort of mandatory standards for a new power distribution panel that includes surge suppression as well as some limited UPS (uninterruptible power source) capacity? And shouldn’t they subsidize the purchase and installation of these devices until the volume of sales drives down the cost to a reasonable amount, or until their service provision becomes more reliable?
I know that Hydro is bleeding red ink in a number of areas, like the need to replace dirty coal, the need to pay for expensive cogeneration, and the need to retire old debt, but in my opinion, these are symptoms of a poorly constructed business model. What they need, is to engineer resilience into their business model. I don’t want to have to replace everything in my home every time they fail to provide clean power to my home and I don’t want to have to pay through the nose to buy products to mitigate the risks associated with these instances.
Law suits are not the way to go…they are too expensive and the only ones that profit from them are the lawyers on both sides. Further, they are not the Canadian way. Rather, Hydro needs to just step up to the plate and consider the needs of their clients and get together with the various standards councils and come up with a strategy for making homes more resilient to the surges and outages until they can fix up their network so that it becomes more resilient. While they are at it, they might want to consider having each distribution panel set up for net metering (so that people can start feeding the grid using solar voltaic or wind energy generated around the home) and even consider having the panel set up to allow external generators to be plugged in (such as gas-powered generators that could be used during a long power interruption). This would allow for better engineered homes that were resilient to power fluctuations, that allow for cogeneration projects and that do all this safely with consideration for folks that have to work on the lines when there is an electrical problem in the neighbourhood.
In short, we need Hydro to take back the playing field and start planning for the future. A bright future if they play their cards right.
Given the interest in solid waste policy in the City of Ottawa at the moment, now might be a great time for you to brush up on some recycling facts. CBC has a page and a video with some interesting information that might inform and entertain you.
The City of Ottawa is currently conducting a review of residental solid waste service levels and this is your chance to have a say before the service levels change (or your tax bill does). The solid waste review has its own web page on the city’s site.
The site includes an on-line survey which allows you to give the city your views directly … democracy in action and all that. I took the survey and it took about 5 minutes to answer. They also have a contact address if the survey doesn’t give you enough flexibility to present your views.
Want an interesting way to explain to kids how consumer demand is created? Want to get some interesting facts about bottled water? What to know what cap-and-trade really means and whether it is a good thing or not? Want to know what all our electronic toys cost the planet? Why not mosey over to the “Story of Stuff Project” for some short, entertaining clips that are ideal for explaining difficult topics in simple English. It’s suitable for kids and adults and, while it doesn’t always provide the answers to life’s woes, it helps you start asking the right questions. Two thumbs up!
I just ran across this interesting post about a small (1000 gallon per day) and smaller (80 gallon per day) solar-powered desalinization unit that could be deployed quickly and cheaply in disaster zones where potable water is hard to come by and electrical power even harder to come by. You can read more about it here: OpenEI Blog: Solar-powered desalinisation.
One thing that has always bothered me about being an environmentalist is that there is never enough good information available to the consumer allowing them to make intelligent decisions. Case in point … what kind of lightbulbs to use in the house to reduce the total carbon footprint and to be generally green.
OC Transpo doesn’t have enough drivers or busses to make the public transit system work and the busses we do have aren’t large enough to meet demand. We need to address this issue in the short, medium and long terms. The municipal vision for a light rail system is a start because it gives us a glimpse of the long-term vision, but it leaves us with a broken system for the next 20 years. Further, even this long-term vision needs better documentation and communication. Continue reading Public transportation woes in Ottawa→
When you start to think about a solar system, you have to remember that the industry is relatively new in Canada. It has been used in Europe for decades, but its penetration on this side of the Atlantic has been marginal until recently. That means that you have to be conscious that some of the product on the market may not have been certified for use in Canada. The components that were installed in our house and that I will be speaking about below were all CSA approved and the “non-packaged” installation proposal that prepared was certified as compliant with the Ontario Building Code by a professional engineer.
It is a sad fact, but if you don’t get any sun, you don’t get any solar heat. But even the grayest areas of the country get a significant amount of sun. Thermomax, a is a Canadian company that uses European technology to provide solar hot water products. Its web site has done a great job of crunching the numbers to see how much water can be heated by a solar unit given the amount of sun available by region in Canada. Its regional comparison page can be found here. They also have a great set of interactive, audio enhanced graphics that explain how solar thermal energy systems work in various configurations. They can be found here.
I will be using their charts to get a better handle on how much money I have saved in the 4 years since I installed my system and will report back to you in a future blog entry.
This is a bit of a departure from my past two posts, but I just saw this film and wanted to share the experience…
Ever wondered what makes the planet tick? Ever wonder whether humanity is really having an effect on the planet and how it works? Do you have children or grand children? Want to see some amazing photography and hear some thoughtful commentary on these subjects? Got a spare 90 minute?
In my earlier post I discussed how we decided to select solar hot water in our new house, but before we made the decision we had to understand something about the technology so that we could evaluate the options available to us. In this post, I will be describing the components involved in solar thermal systems in very general terms and I will wrap it up with a discussion of the “gotcha” points we ran into when implementing our solution.
When we bought our new house about 4 years ago, we wanted to be able to take some control over the utility costs so that when energy prices rise, we would have a bit of protection. There are lots of technologies out there that are environmentally friendly, but not all of them are suited to use in a sub-division and many have a low rate of return on investment. Further complicating matters is the fact that many of the municipal inspectors have no idea what they are looking at when presented with some of the new technologies. So which one to choose… Continue reading Solar Hot Water – Not easy, but worth it!→
