Urgent Evoke

A crash course in changing the world.

To be, or not to be in Nuclear, that is the question !

Dear Evoke Agents,



We all agree that we should look at both sides of the equation: Advantages and Disadvantages.


Here is a table covering both sides; from the web-site: www.nucleartourist.com/basics/why.htm


Please try to have a look, at the major sources of energy.


Comparisons of various energy sources - updated.


Every form of energy generation has advantages and disadvantages as shown in the table below.


Coal: Adavntages: Inexpensive, easy to recover. Disadvantages: Requires expensive air pollution controls, significant contributor to acid rain and global warming, requires extensive transportation system.


Nuclear: Advantages: Fuel is inexpensive, energy generation is the most concentrated source, waste is more compact than any source, extensive scientific basis for the cycle, easy to transport as new fuel, no greenhouse or acid rain effects. Disadvantages: Requires larger capital cost because of emergency, containment, radioactive waste and storage systems, requires resolution of the long-term high level waste storage issue in most countries, potential nuclear proliferation issue.


Hydroelectric: Advantages: Very inexpensive once dam is built, governement has invested heavily in building dams, particularly in the western U.S. Disadvantages: Very limited source since depends on water elevation, many dams available are currently exist source, dam collapse usually leads to loss of life, dams have affected fish, environmental damage for areas flooded and downstream.


Gas/Oil: Advantages: Good distribution system for current use levels, easy to obtain, better as space heating energy source. Disadvantages: Very limited availability, could be major contributor to global warming, very expensive for energy generation, large price swings, liquified Natural Gas storage facilities and gas transmission systems have met opposition from environmentalists.


Wind: Advantages: Wind is free if available, Generation and maintenance costs have decreased significantly, well suited to rural areas. Disadvantages: Need 3X the amount of installed generation to meet demand, limited to windy areas, limited to small generator size; need many towers, highly climate dependant, many affect endangered birds.


Solar: Advantages: Sunlight is free when available, costs are dropping. Disadvantages: Limited to sunny areas, does require special materials, current technology requires large amounts of land for small amounts of energy generation.


This table, from 2009, doesn’t include all possibilities, but provides some info for large

sources.


Some solutions already exist, even if only for a portion of the problem.


So here we are, in need of more sustainable solution!


I will be back later with more ideas to help reducing the negative impacts of peak oil!

Nice summary!

Not to criticize, but I would've included a spot for biofuel also :-p

Very informative and condensed logical bulletpoints!! Thanks for sharing

I think it´s a combination of renewable energies that is a better option than oil, coil and nuclear.

Good synopsis of the various energy generation sources. Like James Lovelock (Author of the Gaia series of books and of course theory) I believe that Nuclear (despite the disadvantages) offers the best possible hope of providing the requisite power needs.

well worth a +KS award

BUT this should only be a stop-gap measure. We must find better technological solutions to harness sustainable resources and develop less power hungry devices. It is ultimately these last two factors that will enable (quite literally) a brighter future for us all.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

The meal

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
