Sustainable infrastructure: The Guide to Green Engineering and Design

By S. Bry Sarte

Renewable energy sources aren’t all that positive. This article sheds light upon downsides of these so called “renewable energy”. For example, when considering solar energy collection as a source it is important to recognize the expensive costs of implementation, hazardous wastes during installation, and land-use associated with it.

A successful energy strategy involves the following four steps:

  1. Reduce energy demand through design.
  2. Use energy effieciently
  3. Select sustainable power supplies
  4. Address climate change and reduce carbon footprint.

Better design can reduce costs and improve performance, which would then reduce energy demand. Passive design strategies rely on energy-independent systems.  These passive technologies include passive solar heating of homes with sunlight and cooling by natural ventilation.

Other passive design strategies include:

Grid orientation

Microclimates

Sealed building envelope

Natural ventilation

Building Design and Orientation

Thermal Mass

Low-emittance Windows

Radiant Barriers

Reflective surfaces

Vegetation

Is the Use of Renewable Energy Sources an Answer to the Problems of Global Warming and Pollution?

Temperature rise is not the only problem global warming has produced. Ocean acidification is one of the most dangerous products of global warming.

This article addresses the different energy concepts not just as better technological options but as tools of social justice and power to the citizens as well. Renewable energy sources are not the absolute side-effects free cure they are known to be. Sometimes their environmental impacts can be as negative as the impacts of traditional energy sources. Solar energy is one of these sources. There are energy requirements and pollution generation associated with materials needed to construct solar power plants. These materials include steel, cement, glass and other hazardous substances. Solar energy harvesting facilities also puts stress upon water resources for their cooling processes.

This article also discussed the ways humans had utilized renewable energy sources throughout history. Renewable energy was used indirectly or directly.  Windmills, drying clothes and crops outdoors, and solar furnaces are some of the direct uses of renewable energy. Indirect ways of using renewable energy such as geothermal streams for bathing and heating were prevalent in the old days.

Reflections:

What is more important, being efficient in how we collect energy & how buildings operate or reduce the energy we use?

It’s not a question of which is more important. Both should exist along side one another on the road to sustainability. The change of everyone’s values

As an individual, how can you reduce your energy intake?

Public transportation, walking, natural light, education and turning off your phone.

How do you think will affect the corporation in terms of producers & gatherers? And how will this affect the society?

If the best case possible happens, that every individual reduces energy consumption, corporations are going to be forced to put resources upon research and production of technologies and products that are more efficient and affordable.  In conclusion, if everyone does their own individual part in the global trend, this wave of change would propagate to an extent that sustainability will no longer be an option but the status quo of our society.
