Green energy is energy that is produced in a manner that has less of a negative impact to the environment than energy sources like fossil fuels, which are often produced with harmful side effects. “Greener” types of energy that often come to mind are solar, wind, geothermal and hydro energy. There are several more, even including nuclear energy, that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.
Green design is to develop more environmentally benign products and processes. The application of green design involves a particular framework for
• Considering environmental issues.
• Application of relevant analysis and synthesis methods.
• A challenge to traditional procedures for design and manufacturing.
Principles of green design:
While the practical application varies among disciplines, some common principles are as follows:
• Low-impact materials:
Choose non-toxic, sustainably-produced or recycled materials which require little energy to process.
• Energy efficiency:
Use manufacturing processes and produce products which require less energy.
• Quality and durability:
Longer-lasting and better- functioning products will have to be replaced less frequently, reducing the impacts of producing replacements.
• Design for reuse and recycling:
Products, processes, and systems should be designed for performance in a commercial 'afterlife'.
Redesigning industrial systems on biological lines ... enabling the constant reuse of materials in continuous closed cycles.
• Service substitution:
Shifting the mode of consumption from personal ownership of products to provision of services which provide similar functions, e.g., from a private automobile to a car sharing service. Such a system promotes minimal resource use per unit of consumption (e.g., per trip driven).
Materials should come from nearby (local or bioregional), sustainably- managed renewable sources that can be composted when their usefulness has been exhausted.
