Meanwhile, solar technology advances are making systems more energy efficient and resistant to shade from trees and buildings, allowing them to produce a larger percentage of
overall household energy consumption.
The project has reduced
household energy consumption by up to 15.2 % and office building consumption by up to 22.8 % through demand response (DR) testing during peak times of electricity usage.
According to Deutsche Bank's Joe LaVogna, every penny that's saved at the pump equates to a billion dollars
in household energy consumption that can be put back into the economy in other ways.
The HEMS system helps consumers use data on driving times, solar intensity forecasts and
current household energy consumption to synchronize electric vehicle charging times with rooftop energy production, so they can maximize the proportion of household - produced energy they use.
This in turn, will push the entire «shelter industry» (from builders to appraisers to real estate agents to lenders) to focus more on homes» energy efficiency, an awareness that will inevitably
reduce household energy consumption and make housing more affordable.
Dietz led a study
of household energy consumption, published online August 31, 2010, in the Proceedings of the National Academy of Sciences USA, that looked at the effects of programs trying to influence energy use, many of which were very effective.
Participants were informed about a fictional study — unrelated to the emission reduction preference question — in which 800 Australians were asked how much they would be willing to reduce
their household energy consumption, either 5 %, 10 %, 15 %, or 25 %.
