**1.1 Personal contribution to green computing**


run at optimal energy efficiency and reduces the time and power required to complete computing tasks.

• Recycling of computing devices and electronic products contributes to the green environment.

Green computing may be considered the study, development, design, engineering, research, production, use, and disposal of computing devices and networks to reduce environmental hazards, energy consumption, and environmental pollution. Computer research, designers, developers, manufacturing companies, and vendors are investing in developing green computing networks and modules by reducing the use of hazardous materials and using improved recycling processes for computing modules and devices. Green computing is known as green information technology (green IT).

In 1992 EPA, the Environmental Protection Agency, started the Energy Star project that initiated green computing research and practice.

Green computing main topics and initiatives:


The book presents new topics and innovations in green computing technologies that can be applied in green computing and electronic industries. The book presents the major topics in green computing and electronic technologies such as renewable energy, green energy, green healthcare, waste, and green computing.

In 2023 Green Computing should be used to protect the world from air and water pollution. In the last decade, the world suffered from severe changes in temperature and climate, air, and water pollution, ocean pollution, and sea pollution. Many countries suffer from severe droughts, seawater pollution, seawater levels rise because of the earth's temperature rise, and severe droughts cause depletion of groundwater reserves, sea pollution, air pollution, and river pollution. Climate changes cause the rapid spread of diseases, viruses, and the extinction of animal species. These changes are almost irreversible. The computing and electronic industry, trucks and cars industry, and the cellular phones industry in the last decade depleted and ruined the universe's natural resources. Dangerous chemicals and toxins that pollute air, water, seawater, and groundwater are part of computers and electronic waste.
