Good Fact

Cannabis Houses = Zero Carbon

- Adam Clare

Hemp, part of the cannabis genus, is a great building material according to researchers in the UK. EcoWorldly has a good write-up on the hemp housing research.

Technically speaking, hemp is the common name for plants of the entire Cannabis genus, although the term is more typically used to refer only to strains of industrialized varieties which are not cultivated for drug use. Because industrialized hemp grows so quickly, requires almost no pesticides or herbicides, controls topsoil erosion and is a significant carbon sink, many environmentalists have been touting the plant as an eco-friendly miracle crop for decades. Furthermore, hemp can serve as a green-minded replacement for many other raw materials which aren’t good for the environment, such as tree paper, plastics and certain clothing fibers. Hemp seeds are also edible, and hemp seed oils offer healthy alternatives to other cooking oils.

Sustainable Energy – without the hot air

- Adam Clare 1 Comment

There is a lot of information out there on how we’re destroying our planet and there’s tons of information about how we can save it (this site looks at saving it). David J.C. MacKay has written a book Sustainable Energy – without the hot air that takes all the climate change information and creates an analysis that is much easier to understand than most writing on the subject. The best part is that you can read the entire book for free.

From the introduction to the synopsis:

We have an addiction to fossil fuels, and it’s not sustainable. The devel-
oped world gets 80% of its energy from fossil fuels; Britain, 90%. And
this is unsustainable for three reasons. First, easily-accessible fossil fu-
els will at some point run out, so we’ll eventually have to get our energy
from someplace else. Second, burning fossil fuels is having a measurable
and very-probably dangerous effect on the climate. Avoiding dangerous
climate change motivates an immediate change from our current use of
fossil fuels. Third, even if we don’t care about climate change, a drastic
reduction in Britain’s fossil fuel consumption would seem a wise move if
we care about security of supply: continued rapid use of the North Sea Photo by Terry Cavner.
oil and gas reserves will otherwise soon force fossil-addicted Britain to de-
pend on imports from untrustworthy foreigners. (I hope you can hear my
tongue in my cheek.)

How can we get off our fossil fuel addiction?

There’s no shortage of advice on how to “make a difference,” but the
public is confused, uncertain whether these schemes are fixes or figleaves.
People are rightly suspicious when companies tell us that buying their
“green” product means we’ve “done our bit.” They are equally uneasy
about national energy strategy. Are “decentralization” and “combined
heat and power,” green enough, for example? The government would have
us think so. But would these technologies really discharge Britain’s duties
regarding climate change? Are windfarms “merely a gesture to prove our
leaders’ environmental credentials”? Is nuclear power essential?
We need a plan that adds up. The good news is that such plans can be
made. The bad news is that implementing them will not be easy.

Six Good Things That Pay for Themselves

- Adam Clare

Being a little greener and a little richer is really easy with these six items that pay for themselves within a year by helping the environment.

5. Programmable Thermostat
Having a programmable thermostat is the easiest way to lower your heating and cooling costs. And having the house temperature right where you want it every hour of the day isn’t bad either. You can find programmable thermostats as cheap as $20 – at that price, it would probably pay for itself many times over in a year.

Taxes Are Good

I don’t know anybody enjoys paying taxes but I know of a lot people who enjoy using what our taxes pay for. Roads, drinkable water, and many other things we use everyday are provided to us from the government (at least in Canada) and these services cost money. A recent Canadian study has done the math and found that in 2006 the average per capita benefit from public services was about $16,952!

Believe it or not taxes are good for you.

The majority of Canadian households enjoy a higher quality of life because of the public services their taxes fund, the study argues.

According to the report, Canada’s Quiet Bargain: The Benefits of Public Spending, the cost of the public services that a typical Canadian household uses annually is the equivalent of about 50 per cent of its annual income.

Green Roofs Coming to Toronto

- Adam Clare 1 Comment

Toronto is set to implement a law that would make green roofs mandatory for tall buildings. Being Toronto, the policy is confused and is arguably not bold enough, but the fact that this is being tabled with support across the city is a very good sign. Torontoist author Toodd Aalgaard has a look at the green roofs coming to Toronto:

After January 30, 2010, according to a draft version [PDF] of the by-law being tossed around today, every building “with a gross floor area of 5,000 square metres or greater shall include a green roof,” meaning that rooftops greater than five thousand square metres in area will require 30% green coverage, with 60% for rooftops exceeding twenty thousand square metres. Further, the construction and maintenance of new roofing will toe strict guidelines laid out in the Green Roof Construction Standard [PDF], ranging from assembly and load bearing to fire safety and plant selection. Even minimal alterations will be subject to City approval.

The Globe and Mail also examines Toronto’s green roof law:

The proposed bylaw would mandate specially irrigated rooftop gardens that are said to reduce air-conditioning costs and mitigate the “urban heat island” effect blamed on pavement and dark roofs.

Part of Mayor David Miller’s climate-change initiative, the move was deferred for fine tuning yesterday and was to return to a meeting next month of the city’s planning and growth committee.
