Each phase of engineering is crucial to the development of projects, throughout the phases one component has become more popular within the industry. Environmental concerns have become a large part of today’s society. Whenever something is built on a large or small scale the effects on the environment must be accounted for in order to ensure safety for the planet and its inhabitants. Many times the large scale manufacturing heavily pollutes to local ecosystems. To stop this, manufacturers are slowly adapting to semi-sustainable factories and some have spent the mass amounts of money to create fully sustainable factories. While manufacturers should aim to be environmentally friendly, the designers of the project should do the same. Engineering projects not only should be developed in a way that is safe to the environment, but should also continue to be safe for the environment when they are deemed completed and used in the as intended. A good example of this are the hybrid and electric cars. These cars are being made to have a cleaner impact on the environment. While hybrid vehicles use part electric and part gasoline to drive, electric cars run solely on electricity. This dependence on electricity is much cleaner and is widely available where gasoline is becoming harder to find. Overall, the sustainability factor of engineering a project is a key factor for the long-term investment. EcoFriendly devices are generally more expensive at startup, however, after using them for a few years will become cheaper than a standard non-EcoFriendly device.
