 Nuclear power has been considered to be environmentally damaging, costly and dangerous, but with ever increasing energy demands and emissions from fossil fuels, is it time to revisit the nuclear option?Bill Gates thinks soAt TED 2010, Bill Gates showed some of the energy analysis his foundation has been involved in. He makes a strong and sensible case that we need to reduce our emissions from energy generation to near zero in order to make a big reduction in the creation of climate change gases. There are two phenomenon at work that are increasing our energy demand:
Figure 1: The Energy Use, Generation and Climate Change Relation.
Therefore we need to quickly move to energy generation that doesn't emit CO2. That leaves really, solar, wind and nuclear along with carbon capture and storage. Each of these generating methods are difficult to implement on a large enough scale to make a big enough impact. Of these, the most promising is actually nuclear. Using advanced technologies, it's possible to create safe and efficient nuclear plants. The costs are better understood for existing technologies and there is work underway to create new generation methods that can consume a lot of the existing nuclear waste. Can we leave nuclear waste to our children's children to clean-up? How big is the security risk? Is it Zen to create new nuclear power stations? These are all big questions and as a society we need to ask them and answer them quickly. With our collective brain-power, a solution to store waste must be found before more power stations are created, even those that are high efficient as Bill Gates proposes. One very important aspect of nuclear waste to consider though, is that it can be captured and managed more readily than that from fossil fuels. Nuclear has no gaseous emissions, it's waste is solid and liquid, thus is more straightforward to capture and much less prone to be released into the environment. So as a technology that can power our growing populations and its need for services in a clean, affordable and safe way, nuclear is looking all the more interesting for our futures. For more information, check out Bill's talk at TED 2010: What do you think? Is nuclear an option for you? Do you think waste can be managed safely? Are there alternatives?
