It is an exciting time to be alive.  We earthlings may have many problems to deal with, but we are also equipped with many tools, terrific minds, and fantastic ways of communications.  My thirst for solutions for earth’s energy problem combined with my online teaching jobs permitted me to travel to various places from time to time to search for answer…to seek lessons learned and wisdom gathered…. Yes, I’ve attended many lectures by many scholars who have studied the energy issue.

Today, I want to share with you a talk by Mark Z. Jacobson, Director of the Atmosphere/Energy Program and Professor of Civil and Environmental Engineering at Stanford University. Professor Jacobson started the talk by explaining what the problem we earthlings are facing today and why is there such an urgency in needing to deal with it quickly:

  • temperatures are rising quickly
  • Arctic sea ice area is decreasing quickly
  • air pollution mortality is one of the leading causes of death worldwide and higher temperature contributes to deaths
  • higher population and growing energy demand will lead to worsening air pollution and climate problems over time

This part of the talk helped me to realize that black carbon (main component of the soot particles) is also a very important factor for causing global warming, in addition to CO2 emission.  Annual premature earthlings’ deaths due to particulates is about 2.5-3 million (in U.S. that is translated into 50,000-100,000 and in Europe, 300,000-350,000 annual premature deaths due to air pollution).

As any good engineer/scholar would approach a problem, Professor Jacobson did not just  alarm us with problems but also evaluated possible solutions both with and without cost considerations.  From reviewing and ranking major proposed energy-related solutions to global warming, air pollution mortality, and energy security, his talk also considered various impacts of the proposed solutions such as water supply, land use, resource availability, reliability, wildlife, and  risk of cancer and nuclear proliferation.  Some data I was not aware of in the past was presented, such as the dramatic increase of organic gases (formaldehyde, 200% and  acetaldehyde, 4500%) and increased ozone generated from using ethanol.  In the final analysis, with consideration of materials, transmission infrastructure, costs, and politics, Professor Jacobson concludes that the best way to power the world is with Wind, Water, and Solar (WWS) technologies.

 


 

By 2030, the cost of using fossil fuel (13.5c/kWh) will be higher than using WWS (8-13 c/kWh) technologies.  Using WWS technologies will also eliminate 2.5-3 million air pollution premature deaths/year and global warming and provides energy stability.  Furthermore, converting to WWS and electricity/H2 will reduce global power demand by 30%.  The greatest concern regarding use of WWS is its variability;this is also addressed by Jacobson’s study by: ( 1.) interconnecting geographically-dispersed WWS;(2.) bundling WWS and using hydro to fill in gaps;(3.) demand-response (provide incentive to discourage use during peak/high demand period);(4.) oversizing peak capacity and producing hydrogen with excess for industry, vehicles;(5.)on-site storage;(6.)better forecasting.

 

 

The study concludes that the best way to power planet earth in the future is with Wind, Water, and Solar (WWS) technologies.  It is feasible both technically and economically.  Its potential barriers are up-front costs, transmission needs, lobbying, and politics.

Dear Readers, this is exactly why I have written the series on Feed-In-Tariff, trying to urge all of our local and federal governments (not just the Floridians or residents of USA, but residents of planet earth) to give all of us the  incentive to participate  in our move toward the Renewable WWS age.  We, as individual home or business owners, may not be spending multiple millions of dollars for lobbying, but we are just as concerned with the future of energy use and welfare of our planet earth as any large utility companies.  We earthlings are all connected. The particulate matters from China or India or radiation material from Fukushima will impact all of us earthlings.  So as  individual earthlings, let’s start by calling attention and action for our immediate communities.  I, here in Florida, will try my very best in asking my community and local government to consider Feed-In-Tariff (discussions available by going to the search box at right and type in “feed in tariff”). Feed-In-Tariff, now rebranded as CLEAN program, may be utilized by individual home owners, small businesses, organizations such as schools, Y’s, hospitals, libraries, local McDonald’s, WalMart, police stations, and large power/utility companies/plant (refer to the piece I wrote on July 13, 2011, Answer For The Future Is In Hybrid Marriage-Solar And Fossil Fuel at http://sunisthefuture.net) alike. I hope you, readers from 85 countries (esp. for those who resides in countries not yet with Feed-In-Tariff), will do the same.  I will try to find a way to set up a petition page within few days.  Please feel free to email me at sunisthefuture@gmail.com if you have any suggestions.  Any of your input will be welcomed.

BIO  for Mark Z. Jacobson (taken from Stanford University web site for energy seminar: http://energyseminar.stanford.edu/node/357)

Professor/Director Jacobson currently sits on the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy (EERE) Federal Advisory Committee (ERAC) to the U.S. Secretary of Energy.  He received a B.S. in Civil Engineering with distinction, an A.B. in Economics with distinction, and an M.S. in Environmental Engineering from Stanford University, in 1988, an M.S. in Atmospheric Sciences in 1991 and a PhD in Atmospheric Sciences in 1994 from UCLA and has been on the faculty at Stanford since 1994.  His work relates to the development and application of numerical models to understand better the effects of energy systems and vehicles on climate and air pollution and the analysis of renewable energy resources. He has published two textbooks and 110 peer-reviewed scientific journal articles. His 2000 finding that black carbon, the main component of soot particles, may be the second-leading cause of global warming after carbon dioxide provided the original scientific basis for five recent U.S. proposed laws on black carbon. He received the 2005 American Meteorological Society Henry G. Houghton Award for “significant contributions to modeling aerosol chemistry and to understanding the role of soot and other carbon particles on climate.” In 2005, his group developed the first wind map of the world from data at the height of modern turbines. He recently co-authored a cover article in Scientific American with Dr. Mark DeLucchi of U.C. Davis and two more detailed analyses in Energy Policy on how to power the world with renewable energy.
