Many people around the world live in smaller housing units in denser neighbourhoods. In Toronto, many freehold lots are between 15-20 feet wide. The typical Vancouver lot is 33 feet wide. We could double the density in the City by encouraging the development of smaller, attached homes on freehold lots that are 15-16 feet wide. Density alone is not enough to create a livable city, but density will help to reduce emissions as well as helping to improve the affordability of housing in Vancouver.39 votes
The Ecodensity planning process kicked off efforts in this area. Laneway housing is a good example smaller, denser housing we are starting to see across the city.
We could use the potential heat from our shower, dishwasher and other source of hot water that we utilize everyday and utilize the energy to heat the hot water again ( Re-use it for a thermal recovery )13 votes
The South East False Creek Neighbourhood Energy Utility is one of 4 systems in the world where heat is recovered from sewage and distributed to the South East False Creek Neighbourhood. for a district energy system.
Vancouver can be a model of a community that works together to reduce its peak electricity demand and thus the generation capacity needed to sustain it. It can do this through proper monitoring of usage in both residential and commercial buildings and financial incentives to reduce beyond savings on the bill. Make Vancouver a model, and once shown successful, this model can be expanded to other BC cities and beyond.10 votes
Have city staff invent a machine to capture/burn the heat from your poo and transfer to hot water tank, or sell it into the city grid I mentioned earlier, exploiting a very domestic source of energy.1 vote
The Neighbourhood Energy Utility (NEU) in Southeast False Creek provides space heating and domestic hot water to new buildings in the area. The system uses sewage heat recovery to supply most of the annual energy demand (70%). This approach is being considered in other areas.

Metro Vancouver is also exploring opportunities to generate energy from liquid waste. See also: http://www.metrovancouver.org/about/publications/Publications/ILWRMP.pdf
