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 […]

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).

Conservation International – A blog to make a difference

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 […]

Uncovering corruption: Charmian Gooch at TEDGlobal 2013

Metroland.com – Trash Troubles

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) […]

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

I just read an interesting paper from the MIT Centre for Energy and Environmental Policy Research and it had some interesting things to say about bio-fuels and politics.  The paper Some Inconvenient Truths About Climate Change Policy: The Distributional Impacts of Transportation Policies (August 2011), by Stephen P. Holland, Jonathan E. Hughes Christopher R. Knittel and Nathan […]

Solar Thermal – What to do when the power goes out!

I spent 6 months living in Kathmandu back in the 90s.  It was commonplace for the power to go off each evening for 2 or more hours and to cope with the outages everyone had battery backups and gas-powered generators. 

But over here in Canada we have never needed battery backups or generators to keep things running.  The electrical system is far more reliable here than it was in Nepal in the 90s.  That being said, we do still get the occasional power outages but for the most part they are little more than an inconvenience.  The same cannot be said for solar thermal systems when the power goes out.  Continue reading “Solar Thermal – What to do when the power goes out!”

Power Surges and Drops – Causing Electrical Problems?

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 […]
