argue for or against the following plan: The public controversy about greenhouse gases?

February 3rd, 2012

Question by : argue for or against the following plan: The public controversy about greenhouse gases?
argue for or against the following plan:

The public controversy about greenhouse gases is too crisis-oriented and off to one side of more important issues, namely a.) the long-term economic potential of renewable energy generation, b.) the dangers of social instability from rich-poor polarization in developing countries, and c.) dangers of corruption of governments of developing countries by a handful of more and more powerful global corporations.

Since no force available can stop or slow down the most rapid possible industrial development in countries like China, Mexico and India, those fearful of long-term harm to the environment should not waste their energies in controversies based in uncertain science. Rather, all should settle on the single goal of quickly developing cost-effective solar, wind, tidal and geothermal power and getting decentralized generation of such power into place everywhere. ‘Politics’ should be put aside in order to accomplish this.

A World Energy Authority similar in some respects to the United Nations should be formed with the express mission of providing detailed planning for rapid transition to decentralized generation of renewable power in every country. This Authority would also provide scientific research and industrial planning. So great is the latent support for such an Authority, provided it remain ‘non-political’ and single-mission focused, that it would only have to open an office and begin to publicize concrete plans for each country for massive support to flow to it. The Authority’s work would capture the imaginations of tens of thousands of young people in the industrialized countries who could do much of the labor associated with establishing thousands of small generation projects. Use of fossil fuel would continue until it became too expensive.

Publicly subsidized, decentralized generation of cheap power world-wide might ‘kill three birds with one stone.’ No plan could be more effective against poverty created by industrial development in very poor countries. This plan would also co-opt more far-sighted corporations who would be hired in the projects, rather than polarizing many in opposition to more stringent controls on emissions, as is presently the case.

Renewable energy generation is potentially cheaper than generation with fossil fuels. There’s no bill for sunshine! Despite imposing capital requirements, pioneering companies could reasonably expect to reap huge profits as sale of super-efficient batteries and photo-voltaic cells, for example, became as common as sale of gasoline is now. What is lacking is a developed, fully-rationalized and well-publicized plan for every country to put decentralized generation in place. As to greenhouse gases, we should aggressively study the climate until we really understand this very complex system.

Answer by liberal_60
Argument against:
The “plan” contains a remarkable and odd collection of false assumptions, impractical ideas, and anti-democratic ideas. Namely.

False assumptions in the plan:

The controversy about climate change is “crisis oriented.” False. The crisis exists mostly in the rhetoric of the contrarians who keep shouting that the scientists of the world are creating a false crisis. In fact scientists are trying to present us with information so that we can take steps to avoid a real crisis in the future.

The science is of climate change is “uncertain.” False. The only uncertainties about climate change are in matters of degree and details. There is ample evidence of warming and man’s responsibility for it. For summaries see these sites from NOAA and NASA:
from NOAA and NASA

http://www.ncdc.noaa.gov/indicators/

http://climate.nasa.gov/

Virtually every organization of scientists on the planet and every scientific publication agrees. There are only a handful of contrarians. You may wish to consider the opinion of the British Royal Society

http://royalsociety.org/climate-change-summary-of-science/

And the opinion of the editors of Science Magazine

http://www.sciencemag.org/content/326/5960/1646.full

Impractical Ideas in the “plan”

Renewable energy generation is “potentially cheaper” than generation with fossil fuels.
This is impractical except maybe in the very long run. There is no evidence that renewable energy is going to become cheap within our lifetimes.

Put aside politics to accomplish the plan. Impractical. Politics is the process by which governments function. There is no alternative method available. We can’t just join hands and sing. Elected representatives of citizens need to meet exchange ideas and goals, and reach compromise solutions. There have always been arguments among competing factions. We have mechanisms to deal with the arguments and resolve them (see U.S. Constitution and Federalist Papers #10 – James Madison).

Anti-democratic ideas in the “plan.”
Creation of a “World Energy Authority” is probably the worst part of this “plan.” The people of the world have never shown any wish to give up their control of their own countries to a world government or anything approaching a world government. A modern democratic republic with a government of elected officials and legislators is imperfect, but in a contest for “best form of government” it is far ahead of whatever is in second place.

I suggest that the “plan” is really just a conservative stalking horse that provides an excuse to do nothing. The author of the plan knows that it would never be adopted, and should not be adopted, but it provides a good talking point — “Those liberals want to enslave you to a world government.”
No. We don’t want a world government any more than the conservatives do.

can a fully solar vehicle be a viable alternative to a petrol driven vehicle?

February 1st, 2012

Question by : can a fully solar vehicle be a viable alternative to a petrol driven vehicle?
i am doing a project on solar vehicles and whether they can be an alternative to a combustion engine
what are some sections i can look into to come to a conclusion.

i need more info on

battery types/materials/combinations.
solar cell materials/power produced/efficiencies/ how they are arranged etc

body materials used and cost of the materials

what other sections should i research to come to a conclusion
performance figures all relate to the cells/battery and the weight, anything else i can add

thanks

Q&A: How many solar panels with one wind generator would you need to power a pop up?

January 24th, 2012

Question by tucher87: How many solar panels with one wind generator would you need to power a pop up?
I am looking at buying a pop up and would like to make it run off of deep cycle batteries but charging these batteries I would like to use a combination of solar panels and 1 wind generator. How many batteries would I need how many solar panels and what wind generator should I buy. I would be powering the lights an fridge and sometimes a AC or Heater.

Thanks
I live in west Texas where it never rains and its always windy

Best answer:

Answer by redsrule4500
Hope it’s not cloudy without wind for a while, you’ll be left with warm food and darkness.

An air conditioner/heater would be such a huge load on the system, wind/solar most likely don’t make sense for an individual, unless you’re on a lake or in California where it’s sunny everyday.

You would need around 200 W for a fridge, 100 W for small lights, and….500 W (?) for heating/air….so you’re looking at some pretty big batteries!! Every 2 hours you will use at least 1.5 kWh of energy.

I bought the Harbor Frieght solar panels because I do not plan on using them to run my entire house. I will use them when I don’t have any grid power so I can charge batteries, run my laptop, ceiling fan, window airconditioner, power tools, etc. The Harbor Freight solar panels are inexpensive, easy to setup and if one breaks you only lose 15 watts.

Solar bottle-bulbs bring light to Filipinos

November 11th, 2011

Millions of the poorest people in the Philippines live without electricity. Many are informal settlers who connect themselves to power sources illegally, often leading to fires breaking out in their homes. Now, a new and cheap solar-light idea is providing an answer for a growing number of Filipinos. Al Jazeera’s Marga Ortigas reports from Manila, the Philippines.
