A crash course in changing the world.
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!
