Green Technology
Green technology is the technology that tries to be environmentally friendly. Its targets are to save the power, low quantities of raw materials and resources, low voltage-low size, which in turn reduces the load on power plants which can lead to less pollution and that is suitable to nanotechnologies or nanoelectronics, biomaterials in electronics, green organic semiconductors This can also mean apply recycling of energy concept to the electrical and electronic device and circuit.
Solar, wind, and hydroelectric dams are examples of green technologies that are safer for the environment and don’t produce fossil fuel waste by-products. Besides the environmental benefits, these alternative energy sources can be used to power a home or a utility power plant.
For VLSI, which is essentially the chips inside the electronics, they could be designed in a way that reduces power, which usually means throttling the clock to adapt to the needed computations, or powering off unused portions, or fabricating in a lower power process. On the manufacturing side, lead-free soldering would be an example of something considered “green”. Another sophisticated technology that replaced the silicon is the Flip-Chip package that uses solder bumps instead of wire bonds while attached to the substrate, leads to the highest electrical and thermal performance. Flip-Chip technology uses in a wide variety of products such as PC chipsets, graphics, and memory packages.
Green Electronics Starting from Nanotechnologies and Organic Semiconductors, some authors say that to allow new functions the solution requires integrating nanocomponents and CMOS circuitry which will overcome the challenges in nanometric scale structure.
Often it is tricky to determine if something truly helps the environment or not. For example, you have to factor in the pollution caused by transporting it, if it were manufactured overseas. You have to factor in the pollution caused during manufacturing the device as well as the materials used to make the device.
Electric cars are an example of something where it is counterintuitive. Early ones at least, and maybe the latest as well, are worse for the environment because manufacturing the batteries and other electronics creates more pollution than conventional cars. Besides, the electricity you are recharging with comes from a power plant that causes pollution. Possibly as much as a gas-powered car.
