When food scraps and organic matter decompose in landfills, methane, a powerful greenhouse gas, is created. If captured properly, methane can be used as a fuel source (known as biogas). Biogas is considered carbon neutral since, unlike natural gas, it does not add any new carbon to the atmosphere. Separating organic matter out of the waste stream and converting it to biogas lowers the greenhouse gas emissions associated with our waste, creates a new fuel source, and makes recycling easier.29 votes
The City has already started a food scraps collection program for neighbourhoods where yard trimmings are collected. These materials are currently composted. With more organic waste diversion, the City will explore opportunties to implement technolgies that produce biogas like gassifiers and anaerobic digesters.
Cloud computing servers that run on renewable wind energy also minimize the need for computer upgrades, high-power servers that stay on all night, and costly software licences. Google has invested hundreds of millions in green power and offers government grade office services at a fraction of current costs. They also recycle computer parts to create their data centres. By using these services, we become greener.12 votes
Good ideas. We are looking for all kinds of opportunities for renewable energy generation, waste heat recovery and energy conservation. Current good examples of waste heat recovery are in newer swimming pools and skating rinks. See a good example though the following link: http://vancouver.ca/parks/info/2010Olympics/pdf/Hillcrest.pdf
Encourage all those stores that vent their unwanted heat from A/C units as well as from coolers/fridges and freezers grocer types and pump that heat into hot water tanks! The technology is available "off the rack". Known as Fre-Heaters..we should be capturing all that vented heat and convert it into hot water. NEW stores should not have such old equipment and instead be encourage to convert at the time of building!5 votes
Great idea. We’re looking for all kinds of ideas to encourage the reuse of waste heat. We will to understand opportunities to include these ideas in amendments to the building code.
Vanier Park's ideal location for wind and reducing the GHG's for Vancouver's 3 major museums would not only be beneficial environmentally but would be a major attraction to the public.17 votes
Great idea. The Vancouver Park Board has examined opportunities for small wind energy generation at locations further west like Jericho.
Half of Vancouver’s greenhouse gas emissions come from burning natural gas to heat our buildings. The large district steam heating systems found at the hospitals and downtown are significant users of natural gas. Converting these existing systems to renewable energy sources would reduce reliance on natural gas and help to lower our greenhouse gas emissions.11 votes
