In this case, two solutions are presented to reduce carbon emissions into the air resulting from the combustion of fossil fuels; as a result, it will reduce global warming. In this paper, these solutions and related questions are to be discussed and analyzed. In the first proposal, AVA Solar proposes using solar energy instead of fossil fuels to reduce carbon emission rates. While solar energy is an excellent method of generating clean “green” energy, it has popular appeal and typically receives high marks for “green” technology. This process raises concerns due to the use of cadmium, a toxic element used in solar panels that raises cancer concerns. As an engineer, the first fundamental canon in the National Society of Professional Engineers (NSPE) codes of ethics is: “Engineers, in carrying out their professional duties, shall consider paramount the safety, health, and welfare of the public.” Therefore, an engineer's moral obligation is to not create or innovate something that harms people. However, as the American Society of Civil Engineers (ASCE) code states, “engineers should strive to improve the environment and improve the quality of life” (sect. 1.f). In another ASCE document, “The Role of an Engineer is Sustainable Development.” Accordingly, an engineer should consider both the first NSPE code of ethics and also follow the ASCE code in his decision. According to utilitarianism in doing the greatest good for the greatest number of people, this means that solar energy should be used to benefit mankind; that the minority group exposed to cadmium, such as workers in the development and production of solar panels, are neglected; unlike the theory of respect for people where everyone counts... middle of paper... o Powertech and its land and project manager in Colorado, urge that his company's proposal be judged on the basis of facts ; however, Douglas has a bias against Powertech, his statement would be different if he didn't work for them and was neutral. Douglas implies the words “good science”, the word “good” is subjective and means different things to different people. “Good” science cannot be pure good; it always has its “bad” aspects attached to it. Consequently, “good” science alone will never provide the desired answers. Ultimately, in my opinion, science cannot solve a problem without creating a new one. There will always be environmental and ethical issues associated with science and technology. As an engineer, you should have a critical attitude towards technology and science and always be cautious and aware of both the benefits and risks/costs.
