what are the purposes of the energy star program
Energy Star Initiated as a voluntary labeling program designed to identify and promote energy efficient products, Energy Star began with labels for computer and printer products. In 1995 the program was significantly expanded, introducing labels for residential heating and cooling systems and new homes.[8] At this time, newly formed energy efficiency programs, administered by ratepayer funded entities such as utilities, agreed through the Consortium for Energy Efficiency to begin promoting their programs using the ENERGY STAR brand. In 2000, the Consortium for Energy Efficiency was directed by members to begin an annual survey of ENERGY STAR impact.[9]
Nuclear fusion Fusion powers stars and produces virtually all elements in a process called nucleosynthesis. The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 606 million metric tons of helium each second. The fusion of lighter elements in stars releases energy and the mass that always accompanies it. For example, in the fusion of two hydrogen nuclei to form helium, 0.7% of the mass is carried away in the form of kinetic energy of an alpha particle or other forms of energy, such as electromagnetic radiation.[3]
