6.1How to apply (AI) technology to improve energy efficiency and better climate change and the security of energy supply as well a resource efficiency?Increasing energy efficiency involves using a reduced quantity of energy to achieve the same or improved product, process or sevice. It is generally measured in a physical unit as the ratio between energy output and energy input. Similarly, resource efficiency refers to the ability to use a reduced quantity or volume of resources to produce the same or an improved service or product and it is measured as the ratio betweenn useful material output and material input, both measured in physical terms ( Dahlstrom and Ekins, 2005).Hence, if it was only (AI) technology can increase energy efficiency or reduce resource effifiency to improve service performance. Then, it will reduce energy wastage. So, it bring this question: How to apply (AI) tool to reduce resource consumptin indentified by analysis of historical resource efficiency?It presents an historial analysis that seems have relationship between energy and resource efficiency improvements and resource consumption across a number of different sectors of activity, including iron, and steel production, electricity generation from coal, oil and natural gas and motor vehicle travel.So, future( AI) technology needs to fight social and behavioural barriers to energy efficiency in the housing sector. If future (AI) technology can improve energy efficiency for home renovations and it can consider the social factors. It is a qualitative investigation technology of the decision making process guiding to teach householders hoe to use overall energy was reduced by the householders' house renovation. It will also bring another question: How can (AI) technology can help householders to do decision making to reduce overall energy consumption by householders' houses renovation, such as reducing energy using when the householder needs to renovate whose house's design, e.g. extensions and additional bedrooms or bathrooms . So, future (AI) technology can be needed to help low income householders to increae energy efficiency and reduce energy consumption when their homes need to renovate whose houses' design, e.g. extensions and additinal bedrooms or bathrooms or bookrooms or children toy rooms at hoomes.Due to low income householders were concerned about energy consumption for environment and economic reasons, upfront costs rather than life-cycle costs were considered more important when the low income householders need to renovate to extend extra bedrooms, bathrooms, studyrooms to buy extra electronic appliances to install them in these rooms to use. Then, they will be concerned energy awareness how will be more consume when the low income householders choose to renovate their homes design to extend more rooms to feel more comfortable, or large size, but they also need to consume or use more electrciity or gas energy for extra electronic appliances in these rooms possible as the same time.Hence, future (AI) technology needs to assist these low income householders how to reduce or avoid to ue extra more energy, when they renovate their homes' designs to cause to need to buy extra more electric appliances to use more electricity or gas energy at homes. Moreover, future (AI) technology ought have effort to help any countries' buildings to be efficient energy saving buildings to be efficient energy saving buildings to help householders to use less energy to live in their builsing efficiently. When the country's overall buildings can use energy efficiently, it won't only bring energy saving benefits, even it can bring the country's economic cost to be reduced, due to any building' energy efficient using high technological method.
