Thank you for visiting the site for Portland Peak Oil. We’re a grassroots group of concerned citizens in Portland, Oregon who have come together to create community, prepare and do public outreach in anticipation of coming crises due to the end of cheap energy.
Save Energy in our Buildings
Tinting the windows in residential and commercial buildings reduces the transfer of energy through the glass and thereby reduces the energy used to heat the building in winter and cool the building in summer. Using energy more efficiently now plays an increasingly important role in maintaining our living standards in the face of rising energy prices.
As the world moves beyond peak oil the price of oil will inexorably increase. Alternative and renewable energy and energy conservation measures like tinting the windows will receive greater attention. While tinting the windows in a home or office to reduce electricity consumption will have very little direct effect on oil use, it will feed into the overall energy supply mix, which now includes recognition of the need to reduce carbon emissions arising from the use of carbon based fuels.
Portland Peak Oil was a grassroots group of concerned citizens in Portland, Oregon who came together in 2005 to alert people of a coming crises due to the end of cheap oil. The group grew and evolved and as new members joined, new interests were embraced. The group known as Portland Peak Oil was subsumed within a larger group called the Dirt in 2010.
This site is now dedicated to raising public awareness of window tinting of residential, commercial and public buildings. Glass is the single largest cause of heat gain and heat loss in a building. The US Department of Energy state that heating and cooling accounts for about 56% of the energy used in a typical U.S. home, which makes it the largest energy expense for most householders.
- Since glass is the largest single contributor to heat gain and loss in a building and over half the total energy cost of a US householder is heating and cooling their home it makes good economic and environmental sense to look at improving the energy efficiency of the windows.
Window tinting can block up to 80% of the solar energy (heat) passing through the glass to which it is applied in summer and significantly reduce heat loss through the glass in winter. Window tinting is the most cost-effective building insulation available and its widespread adoption would have a major impact in reducing energy consumption nationally.
