Vancouver’s 100% Renewable Energy Goal
$this->bbcode_second_pass_quote('', 'A')s we reported back in April, Vancouver’s City Council has voted to transition 100% to renewable energy (not just electricity, but all energy). Deputy City Manager Sadhu Johnston discussed this plan and plenty of positive clean energy Vancouver initiatives in this final Renewable Cities PechaKucha presentation:
Some of the highlights from Sadhu’s presentation include the fact that the city has seen a 6% decrease in greenhouse gas emissions while seeing a 30% increase in its population and a 20% increase in its number of jobs. The city also has 98% greenhouse gas–free electricity, and 31% renewable electricity.
Some of the key ways Sadhu noted they could hit 100% renewable energy were by:
building the city so that people could walk places
adding bike infrastructure (Vancouver had a 400% increase in the morning bike commute on the route pictured below when they added that protected bike lane)
electrifying public transit, and incentivizing a switch to electric cars and trucks
greening building codes
using district energy systems and better using sewage and waste heat for energy
cleantechnicaThe following is a very interesting discussion by commentator from FOE on the topic of green growth or steady state:
Green growth or steady state? Rival visions of a green economy$this->bbcode_second_pass_quote('', 'S')ooner or later, humanity will have to accept the constraints of a finite world, writes Guy Shrubsole. But two rival economic visions offer conflicting paths to sustainability. In fact, it's time to stop arguing and get on with it - going for green growth in the near term, while aiming for a deeper societal transformation.
But where political establishments are adamant they can be addressed through a process of 'green growth', others insist this is a nonsense, a contradiction in terms - and that only through replacing growth with a steady-state economy can we be sustainable. So who's right?
In what follows, I try to summarise the best arguments and counter-arguments put forward by the two sides. This is a vast and complicated subject, so I don't pretend to be comprehensive, or conclusive. But as Rio approaches, I hope this can help kick off a deeper discussion about what remains the most fundamental faultline in environmentalism.
I'm forced to conclude in a way that I find very unsatisfactory: by sitting on the fence. I'm not convinced that either side - green growthers or steady-statists - has yet won the argument, even after forty years of doing battle.
The historical evidence for green growth is threadbare, even nonexistent - though this should give no one, not even the steady-statists, any cause for pleasure. What's more, we can't assume the past will determine the future (in this debate, if it does, we're stuffed either way). Rather, the two sides ought to take one another far more seriously, and see the merits of a combined programme for transition.
To address our failure to achieve green growth means, on the one hand, investing far more in green technologies and doing everything in our power to decouple emissions from growth.
