Why U.S. Homes Should Be Greener


| 7/17/2014 10:14:00 AM



According to statistics, Americans are responsible for roughly 25 percent of global emissions of carbon dioxide, which is more than any other nation and on a per capita basis is 6.6 tons of CO2 annually. In the U.S., most carbon dioxide (98 percent) is emitted as the result of burning of fossil fuels.

Surprisingly residences account for as much as 21 percent of U.S. CO2 emissions with 68 per cent of residential emissions coming from the consumption of electricity and 80 per cent of those coming from the burning of coal at coal-fired power plants, which residences use for lighting, air conditioning, heating and other household appliances.

In order to help reduce energy consumption and CO2 emissions, and to achieve the rule put in place to reduce America’s carbon dioxide emissions by 30% from 2005 levels, housing in the US needs to be made more energy efficient through improved insulation.

Although efforts have already been put in place to help reduce CO2 emissions from residences, for example, the Leadership in Energy and Environmental Design (LEED) is helping buildings save energy, water, resources and money, efforts need to increased considerably further in order to reduce residences carbon emissions by a significant amount.



Much of the existing housing stock in the US is not insulated to the levels it should be today, with older homes in particular, significantly using more energy than they should, which is not only bad for the environment but also leading to higher heating and air-conditioning bills. Newer homes tend to be much more energy efficient because they have been built with ‘being green’ in mind.  However, while some newer housing is being built in the US, a large percentage of US housing is old.
