Abstract
Few steps like turning off the tap while brushing your teeth, turn off the lights when leaving a room, recycle waste or using recycling bags are considered sustainable attitudes. Sustainable development is one that meets the needs of the present generation without compromising the future generations and it doesn’t deplete resources for the future. Consume with conscious is a sustainable habit and usability of products contributes to this. The goal of this paper is to prove that the usability of software contributes positivity or negativity for sustainability. By calculating the amount of electrical power dissipated by an electronic device, you can discover the amount of energy lost by it, and consequently, to relate this quantity with the amount charged by the concessionaire for each kWh of energy used. It was concluded that a software with low usability cause users to lose a lot of time interacting with it and thus spend more energy and money that goes against the concept of sustainability.
