The same old energy mix — The Japan Times editorial

The same old energy mix — The Japan Times editorial. 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 […]

Making investment practices more sustainable – Another great TED talk

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 […]

What the heck is an Earthship? … maybe an idea whose time has come!

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).

Being green can sometimes be as simple as following the frog

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 […]

Pool leaks are an environmental disaster!

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.

Hybrid cars – one buyer’s thoughts

Back in 2009, my family bought a 2010 model year Honda Civic Hybrid.

Not everything environmental is about new technology…sometimes it is doing what we do in a smarter way.

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 […]

Who’s making money on bio-fuels and are they a good alternative to oil?

Holland, Jonathan E. Hughes Christopher R. Knittel and Nathan […]

An open letter to the plastics industry

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 […]

Solar light bulbs for pennies (Isang Litrong Liwanag/a litre of light)

A litre of light

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).

How do you decide which green technology to use to light your home.

Image via Wikipedia

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.

For years now, we have been asked to consider moving to compact fluorescent lightbulbs because they last longer and they are far more efficient than the incandescent bulbs we have used for the last hundred years or so.  Continue reading “How do you decide which green technology to use to light your home.”

Public transportation woes in Ottawa

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”

So, what solar equipment do I need to buy (part 1)?

 Solar system components

 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.

The solar collectors we use in our house are the CAREarth Vacuum Tube Solar Collector SJ Series Heat Pipe Technology.  Continue reading “So, what solar equipment do I need to buy (part 1)?”

But, it’s always cloudy and cold here! What good is solar heat here?

How does solar thermal work?

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.

Solar Hot Water – Not easy, but worth it!

Traditional Roof Mount
Traditional Roof Mounted Solar Hot Water Array

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!”
