1) Residential and commercial energy use for space heating, water heating, and space cooling accounted for over 80% of total energy use and greenhouse gas emissions in 2003 according to the document. 2) The document outlines opportunities for reducing energy use and emissions from buildings through the increased use of renewable technologies like biomass heaters, solar thermal, and geothermal heat pumps for space and water heating. 3) It proposes several policy measures that could help increase the use of renewable heating technologies in Canada like a Green Heat Partnership, mandatory consideration of renewable options, and emission credits.
