Although there may be plenty of oil left in oil tar sands there are a couple of problems:
- Its going to be really expensive (and energy intensive) to extract and process.
- The levels of Carbon Dioxide in the atmosphere are already way too high; just because theres still plenty of oil around doesn't make burning it a good idea.
On the subject of Nuclear, there are also problems:
- We have no idea how to deal with waste thats toxic for 1000's of years. Don't believe anyone who says it can be buried in geologically stable holes in the ground. Its a lie. Theres nowhere on the planet that can be guaranteed geologically stable over that sort of timescale.
- Nuclear fuel is extracted from uranium ores which have to be mined and processed, a very energy intensive process which uses lots of oil fueled excavation equipment.
- Theres not that much uranium ore around anyway, only enough to last a few decades if the whole world starts using nuclear as their main means of power generation.
Rant, rant, rant.
