Transitioning to Renewables

In addition to efforts toward energy efficiency, a transition to renewable or low-emission energy sources – for heating, cooling and power – will be required in order to make large, long-term GHG emissions reductions.

Renewable (and low-emissions) energy sources can displace fossil fuels, e.g. natural gas for space heating, thus reducing emissions. Renewables can also be implemented at different scales: large, commercial scale wind power generation; capturing heat from large wastewater infrastructure at the neighbourhood scale; or geoexchange heating and cooling systems for individual buildings.

Many renewable sources have the potential to be integrated within a district energy system.

Wind energy is a pollution-free, infinitely sustainable form of energy. It doesn’t use fuel; it doesn’t produce greenhouse gasses, and it doesn’t produce toxic or radioactive waste. 

Feasibility of a particular energy source depends on a variety of factors including type of use (e.g. residential building vs. recreation facility), scale (e.g. building scale vs. neighbourhood scale), technical feasibility, source capacity, environmental impact, and the cost of developing it. Beyond the building scale, more detailed feasibility studies are often required for implementation.
