      << File: ATT00028.htm >> Reflected light off a white roof leaves the earth as light. An infrared
      satellite image reads a white roof or green foliage as 'cooler' than
      buildings, concrete, asphalt, etc.

      Light captured and converted into electrical by a solar cell, or light
      captured eons ago and converted by plants into oil. When either one is
      converted (released) as either mechanical energy, or some other energy like
      light or microwaves, it is converted at some level of inefficiency. That
      inefficiency becomes sensible heat. A hot light bulb, a hot motor, a hot
      engine, etc. More people using more energy, from any source and in any form,
      will result a hotter climate.



      Conservative energy practice is the only 'definitely positive' alternative
      energy 'system'. However, as a side issue, if solar cell usage leads to
      more conservative energy usage practices, then that is a good thing. But so
      would using a car that gets 30+ mpg or a house that is designed to require
      less energy to make a family comfortable.



      I think your statement, slightly adjusted as ".we must reduce our demand for
      fossil fuels " reads better.

      Decent point Gary but;



      Who is to say that painting all the roof's white might have a negative
      cooling effect on the atmosphere? Come on, we can displace the effects of
      the new darker colored cells, (solar thermal absorbers are darker by design
      than solar electric which can be nice blue if you like,) by painting an
      equal area white making it color neutral if you like.



      An overriding concern it that I feel as what 5% of the world population we
      cannot continue to consume 27% (?) of the world's energy. We must reduce
      our demand for fossill fuels and one good way to do this is solar thermal or
      electric. They are proven technologies now and can make an impact. If we
      are to be the world leader we should lead.

      The effects you talk about could be dealt with, the positive far outways
      this don't you think?

      Incredible breakthoughs or not, one thing I have to point out is that solar
      cells should not be thought of as free or even renewable. The energy they
      capture is not free. They make electricity by capturing energy that is
      otherwise reflected back into space. All this captured energy will be
      released as sensable heat.



      The other point is that every solar cell I have ever seen is very dark color
      and that on a sunny day I assume you can fry and egg on them during
      operation. And they would remain warm for a few extra hours each night.
      Sounds like a hot city that has 1/2 of the area of every roof covered in in
      solar cells.



      This vision of a 'solar roof on every house' is the opposite of significant
      eco design efforts to try to cool cities by adopting building specifications
      changing commercial roof colors to white and residential roofs to very light
      shingles (plus a cooler roof means cooler living working space). Or better
      yet like USGBC-LEED and other efforts that support 'green' garden roof on
      new commerical buildings.



      What is the best approach to satisfy both concerns? Is there a light colored
      solar cell? Any one have a design for a solar cell garden roof?

      I read ocasionally Scientific American, Discovery, Science etc. - they are
      great for 'what if' and 'think about this' , but not very good predictors at
      all. What were they saying about fuel cells 10 or 20 years ago? My son get
      Popular Science - a recent article is called "Hydrogen's Bomb - Decoding the
      Hype". My favorite recent new science release? The spinach plant that is
      designed to generate electricity (no joke) (here's a joke: It is a good
      thing since will require more candle lit dinners - cause after you finish
      your salad it's light out!)

      Mr. Malone,

      I quite dissagree with you on many of these issues, and so do most
      scientists. Read any of the articles today on energy in Scientific
      American, Physics Today, Discovery, Science, .... and you will find that our
      current oil consumption trends can only be sustained to about 2050, plus or
      minus 20 years. Renewable energy is growing exponencially. Europe is
      aiming for 20% renewables by 2020. I believe many of the US States already
      have similar goals and many more will join in as time goes on. There will
      be a change within the next lifespan.



      Even the "Oil" companies realize this and have published reports that say
      so. They are starting to call themselves "Energy" companies and investing
      quite heavily in renewable energy. See Shell Solar, Shell Wind, Shell
      Renewables, BP Solar, GE Solar, GE Wind, for example. And if the oil
      companies don't lead, the electronics companies will. Sharp is already the
      leading manufacturer of solar cells.



      I don't know how you did your math about not enough solar energy in New
      Jersey (is that the state with the highest energy to land ratio and the
      least sunny state?). But the math I have done shows that I can supply all
      of my Houston household electrical needs (averaged) by covering half of my
      roof with solar panels. No breakthrough technology needed; it already
      exists. If you trend retail electric prices and solar PV prices, you will
      see the cost cross in the year 2025 - then it will be more economical to buy
      PV than grid electricity!



      If you read up on the technical progress of photoelectrics, you will see
      incredible breakthroughs in the last 10 years. Right now, solar cells are
      expensive because production can not keep up with demand. And new record
      breaking production facillities are being opened each year.



      If you want a "heart felt" change, read the July-August issue of Renewable
      Energy World each year and see the growth of RE for yourself. It is
      amazing. Maybe we can discuss some of the facts at the next HREG meeting,
      Sunday, 2:00pm, Jan 30th at TSU.

      Sincerely,

      Chris

      All this discussion is interesting and heart felt. The following is not
      intended as a rant, but to put our problem in perspective.



      Our government, both parties, is so tied to big oil money, .

      It would take solar panels covering every square inch of the state of New
      Jersey just to equal the energy used in New Jersey. So the size of the oil
      dependency is almost beyond our reason.



      A breakthrough, one not foreseeable by current science is most likely the
      only hope in the US. Outside the US there may be some help because of the
      different mind set of the non US-Oil cartel.



      China is graduating more engineers & scientists each year than the US
      graduates all college students of all degree fields. China has a massive
      energy problem. They also have a growing economy that it partly controlled
      & partly free market. As they inevitably pass the US number of educated
      citizens (check out our schools systems if you doubt this) and the
      controlling government forces capital & research in to alternative energy
      research because of their vast needs and lack of resources they may turn
      this thing around.



      I hope I live long enough to see the beginning.

      In the interim, conservation, voting, getting activity in politics may be
      the only drop in the bucket we have. I hope I'm wrong.
