Kuwait Goes Nuclear
Good for them.
We should follow their example and switch to nuclear energy as much as possible as well.
Yep, Responsible Nuclear energy could virtually solve our Energy Crisis. Spent fuel rods can be reprocessed. 0 emissions and cheap power. What's not to like.

Comparative costs data: California regulatory agencies (May 2008)
On May 13, 2008, the California Energy Commission and the California Public Utilities Commission released a comparison of the costs of of new generating capacity from various sources. The analysis for the comparison was prepared by Energy and Environmental Economics, Inc., a consulting firm that prepares studies for utilities, governmental regulators, law firms, and non-profit agencies. These estimates include firming resource costs.
Busbar cost in cents per kilowatt-hour in 2008 dollars:
Coal Supercritical: 10.554
Coal Integrated Gasification Combined Cycle (IGCC): 11.481
Coal IGCC with Carbon Capture & Storage (IGCC with CCS): 17.317
Gas Combined Cycle: 9.382 (assumes $5.50 to $6.50/MMBtu for gas)
Concentrating solar thermal (CSP): 12.653
Busbar means the price of the power leaving the plant. All capital, fuel, and operating costs are taken into account in busbar costs.
The spreadsheet containing these costs can be found at CPUC GHG Modeling.
Nuclear is best for base-load power. Wind & Solar are spontaneous & need Hydro for storage. Natural Gas & Coal coal balance load & peak power.
Exactly how are those costs calculated is what I want to know. A nuclear plant requires a very large initial investment. So the longer it operates The better cost to gain ratio you will have. So when they figured those costs did they figure that in at all?
Another point here, when a nuke reachs the end of its lifespan, ussually about 20 years, it is a very expensive process to remove the core, and ship it to a safe storage facility. When a wind turbine reachs it expected life span, also about twenty years, they simply use a crane to remove the old turbine, and install a new one on the tower. Then the old one goes in for a rebuild.
