I live in the same town as a nuclear reactor used for scientific research.
Do I have an issue with nuclear energy? No, not really. I think it's the best alternative we have at the moment to fossil fuels. It's unfortunate that it's still our best alternative. The fact is, if we want to reduce carbon emissions, we have to take coal plants offline, take gas-burning cars off the road, and enforce carbon limits.
Generating power without fossil fuels means nuclear energy right now--and willravel, as for nukes not powering cars--well, directly they can't. But indirectly, via electric cars and the other alternative cars out there (such as the TOTALLY AWESOME Air Car:
http://www.theaircar.com/), we CAN use nuclear energy to power our automobiles. Hydrogen cars also require large amounts of electricity to release hydrogen via electrolysis in order to create the hydrogen fuel cells needed for the cars. Most alternatively powered cars are just storing energy somehow, after all.
As for getting fossil-fuel cars off the road now...really, eating meat is nearly as environmentally damaging. And well, I'm not gonna stop eating steak or driving my Volvo--but I am going to do what I can to mitigate the choices I make, which means recycling, driving less, using public transport when possible, cutting back on electricity usage, switching to a laptop from a desktop computer, turning down the water heater, and just generally living a lifestyle with less impact. Seriously, all any of us can hope to do is that--try and live a lifestyle with less impact. No impact is impossible--compromises have to be made.
