Energy
Taiwan’s Transition to Sustainability
Water
November 11-14, 2012 近代工程研討會 Taipei, Taiwan
To be competitive in the global markets, Taiwan needs plans for sustainable development of energy and water resources.
The country’s political system is perpetually planning for the next election cycle and is incapable of laying out roadmaps for transitions to energy and water sustainability.

Effects of combustion emissions on precipitation extremes

How can humans affect clouds?By changing CCN; cloud properties are a strong function of their concentration.This phenomenon is known as aerosol indirect effect.
The aerosol indirect effect can lead to climatic cooling by:• Increasing cloud reflectivity (albedo)• Increasing cloud lifetime & coverage.

Lower Albedo
Polluted Environment (few CCN)
(more CCN)

Asian pollution plumes.Is the indirect effect globally important?Biomass burning in the Amazon.
Pollution is a global problem. CCN are emitted together with greenhouse gases.
Is the indirect effect important?

Cloud Radiative Properties
Cloud Droplet Number and Size? Well
Defined
This problem has historically been reduced to finding the relationship between aerosol number concentration and cloud droplet number concentration. Empirical relationships are often used.
Indirect effect s are very complex

Water efficiency and productivity

Domestic vs. industrial water usasage
Jianyao Chen, et al (2006)

Water scarcity affects economic development in the underdeveloped countries
Water scarcity
It’s also important for biodiversity in the developed country

Substitution: Rainwater (from roof) and graywater (laundry, dishwasher, and bathing) can be used in place of drinking water for a variety of activities.
Water efficiency and productivity
Regeneration: Domestic waste water can be treated to replenish groundwater
Reduction: water productivity can be increased by reducing the volume of water used for a fixed value of goods and services.

In addition to resource augmentation, water efficiency and productivity are important

Groundwater depletion and replenishment
![Page 23: David T. Shaw ( 蕭台戈 ) State University of New York at Buffalo Amherst, NY](https://reader033.vdocuments.net/reader033/viewer/2022061502/56816393550346895dd48b55/html5/thumbnails/23.jpg)
The imbalance is made up by groundwater
![Page 24: David T. Shaw ( 蕭台戈 ) State University of New York at Buffalo Amherst, NY](https://reader033.vdocuments.net/reader033/viewer/2022061502/56816393550346895dd48b55/html5/thumbnails/24.jpg)
All of these environmental issues are linked to each other, and eventually are tied to water resources which are the
focus of our discussion.
Hydrology cycle and water resources

Two GRACE satellites The positions of which change in response to variations in Earth’s gravity field
Gravity Recovery And Climate Experiment (GRACE)
![Page 26: David T. Shaw ( 蕭台戈 ) State University of New York at Buffalo Amherst, NY](https://reader033.vdocuments.net/reader033/viewer/2022061502/56816393550346895dd48b55/html5/thumbnails/26.jpg)
When the two spacecraft pass over the ocean, the distance between them is unchanged
How GRACE works
when the lead spacecraft encounters a change in gravity over a denser land mass, it pulls away from the trailing spacecraft, which is still over water.
The lead spacecraft moves back over water, but now the trailing spacecraft changes position in response to the greater pull of gravity over the land mass.

Water and energy security in Asia-Pacific region in the face of climate change and rising populations is an issue of global importance.
Sustainability science has emerged over the past two decades as a response to critical issues of the 21st century.
As the 2008 global financial crisis showed us, too many policy failures of technological/economic/environmental/social (TEEC) problems are fundamentally failures of knowledge.o Germany’s carbon-neutral energy revolution is facing many uncertainties.o We propose to pursue a multidisciplinary approach and establish new sustainability science
institutions for efficient knowledge creation through TEEC model simulation and integrative systems design.
