Energy Star is a similar labeling program, but requires more stringent efficiency standards for an appliance to become qualified, and is not a required program, but a voluntary one. Essentially, an Energy Star label shows that the appliance you have chosen uses less energy and will save you more money than its non-energy star rated competitor.
Energy Star (trademarked ENERGY STAR) is an energy-efficiency program administered by the U.S. Environmental Protection Agency (EPA) in partnership with the U.S. Department of Energy (DOE). [ 2 ] [ 3 ] [ 4 ] The EPA establishes energy efficiency specifications, and those that meet these specifications are eligible to display the ENERGY STAR logo.
The process is sometimes known as "hot dry rock" (HDR). [134] Unlike conventional geothermal energy extraction, EGS may be feasible anywhere in the world, depending on the cost of drilling. [135] EGS projects have so far primarily been limited to demonstration plants, as the technology is capital-intensive due to the high cost of drilling. [136]
Smart glass, also known as switchable glass, dynamic glass, and smart-tinting glass, is a type of glass that can change its optical properties, becoming opaque or tinted, in response to electrical or thermal signals. This can be used to prevent sunlight and heat from entering a building during hot days, improving energy efficiency. [1]

In general, matter in diffusive motion carries with it some internal energy, and some microscopic potential energy changes accompany the motion. An open system is not adiabatically enclosed. There are some cases in which a process for an open system can, for particular purposes, be considered as if it were for a closed system.
Sustainable product development (SPD) is a method for product development that incorporates t he Framework for Strategic Sustainable Development (FSSD), also known as The Natural Step (TNS). Incorporating sustainability aspects early on in the product development process has been claimed to offer competitive advantage. [1]
Transparency can provide almost perfect camouflage for animals able to achieve it. This is easier in dimly-lit or turbid seawater than in good illumination. Many marine animals such as jellyfish are highly transparent. Comparisons of 1. opacity, 2. translucency, and 3. transparency; behind each panel (from top to bottom: grey, red, white) is a ...
