Energy conservation is a part of the concept of Eco-sufficiency. Energy conservation measures (ECMs) in buildings reduce the need for energy services and can result in increased environmental quality, national security, personal financial security and higher savings. It is at the top of the sustainable energy hierarchy.
Eco-efficiency is the relationship that exists between the economic value of a good or service offered in the market, and the environmental impact that its production generates for the human ecosystem. Thus, the lower the environmental impact generated by said product, the higher its eco-efficiency rate.
The search for eco-efficiency of goods and services aims to preserve the environment, that is, to guarantee a natural environment suitable for human life, in conjunction with a normal production of goods and services.
John Locke had the idea of natural rights, which he stated were life, liberty, and property. The founding fathers changed property to the pursuit of happiness
