Waste & Energy
Waste products and fossil fuel usage are in part byproducts of our civilization and in part they are drivers of our civilization. Disposing of waste and managing fossil fuels present tremendous challenges to our society. We know that climate change is going to have a significant effect on the world, so that the world 100 years from now is quite different from the world today. We know that our waste cannot simply be thrown out, or it will pollute our environment. This presentation will outline specific examples to illustrate the problem.
I want you to take out your phone. It's probably already out. When will you be replacing that phone? Within the next year or two, maybe three if it's a new one. What's in a phone and where does it go? Electronics are a major category of waste, and a massive environmental challenge. Batteries are a major issue and electronics are a major contributor to toxic waste in our landfills (Clean Air Council, 2014).
Slide 3: Some companies recycle old phones. This is done by separating the toxic materials from non-toxic. Batteries must be removed. Many components are burned, and shipped to the developing world for this disposal to avoid polluting our cities....
Energy and Its Sources Energy is an important element in daily life since it used for many activities like moving vehicles, promoting growth of the human body, and enabling humans to think. However, energy can be found in various forms like sound, heat, motion, and light though they are classified into kinetic and potential energy. While kinetic energy is the motion of substances, waves, objects, molecules, and atoms; potential energy is
At the same time, economic growth and prosperity is definitely linked to energy consumption. Following the path of greatest energy efficiency would have us still living in the Middle Ages, and though certain nations might not be as exploited as they are today through our more efficient trade mechanisms (that burn less efficient fuels), many people in the developed world would be entirely unwilling to make this trade (Jones 1997). The
Energy is an essential force powering society, industry and in the end our everyday lives. Generally, energy sources can be classified as non-renewable and renewable sources. Non-renewable energy sources are those that can not be replenished or made again in a short period of time. Renewable energy sources on the other hand can be replenished in a short period of time (Energy sources, 2011). There are three main sources of energy
It is clear that if we as a species are to survive the 21st century and beyond, we must concentrate on changing our approach to the environment by reducing our carbon "footprint" and exploring the idea of renewable energy sources that will be appropriate for a growing global population. The Turning Point -- Transition to Renewable Energy -- the bleak reality is that the age of oil has dominated global
Tidal energy could be another option, which has limited access. This means that energy plans should include a combination of all alternative types of energy that can be used in a certain region. All things considered, energy conservation is an issue that raises many concerns on global level, institutional level, and individual level. At global level, it is the world's states' responsibility to agree upon general directions that need to
Garages on the outskirts of the city will house cars and light rail transportation will ferry commuters to their jobs in Masdar. There will be solar thermal farms to supply about "a quarter" of the needed electricity, Loffe goes on. The city of Masdar is proposed to accommodate up to 50,000 permanent residents and jobs within the city will be provided for about 40,000 commuters. How hot will it
