They don't build office towers like they used to--and that's a good thing. Nowadays, they're built with sustainability in mind, and here in Toronto, there are hundreds of projects with LEED certification--which stands for Leadership in Energy and Environmental Design.

They're everywhere - those blue window decals that suddenly popped up at stores, restaurants and cafes earlier this summer. But what is Quench and who is behind it? I recently connected with Tyler Miffin, the director and co-host of an award-winning TVO documentary series called The Water Brothers who filled me in on these very questions.

As it turns out, Miffin and his brother are the masterminds behind Quench - an app that has been downloaded thousands of times and is now available for iPhone, Android and Blackberry smartphones. The basic idea of the app is to help people find the closest place around them where they can get a free drink of water, or a place that will refill their reusable water bottles for free.

To date, there are more than 1200 refill stations around Toronto that will fill peoples water bottles for free, and there are plans to expand the program (and app) to other cities.

The Live Green Toronto Festival has grown in the seven years since its inception as the environmentally conscious lifestyle has moved from the fringe to the mainstream. This past Saturday, Yonge Street and Yonge Dundas Square were packed with pedestrians exploring green products and services. Organizers wisely situated vendors solely on the west side of the street, easing congestion and preventing the whiplash that can result from trying to take in both sides of a festival corridor at once.

The 2012 Eco-Wheels Show at The Distillery District this weekend showcased some of the latest styles and trends in electric bicycles, electric motorcycles and electric cars. The Amego "Batmobile" e-bike prototype (lead photo) immediately caught my attention with its solid look and badass matte black finish.

The Green Living Show, the largest green consumer show in North America, is back in Toronto for its sixth year. I checked out the show for the first time in a few years Friday evening, and was pleasantly surprised by the variety of vendors, activities, information, and interactive booths; and of course, by all the delectable food samples just waiting to be tasted. With over 400 exhibitors showing off their latest and greatest green products, services, and fare — everything from organic wines to natural beauty products to innovative green technology and the chance to test drive an electric car — it can be overwhelming to decide where to start, what's worth seeing, and what's worth skipping, so I've narrowed it down to my top five picks from the show.

Bringing EV Fest -- Toronto's fall festival of electric cars -- to The Brick Works from last year's event held in a Toyota-Lexus dealership made sense on many levels.

EV Fest 2011 showcased electric car and bike offerings in a space where nature, culture and community intersect. Held in The Kilns and Holcim Gallery on Sunday, it was neat to see such modern-day transportation options inside such the heritage property.
