Global Warming, er Climate Change is a National Security Threat
|
Quote:There are plenty of reasons beyond climate change for us to wean off fossil fuels, whether it's happening or not, no matter the cause. I agree. We need to find something better. Current nuclear technology is safer and cleaner, but it's a no go politically. It's also about 50% more expensive than either coal or natural gas. There are some promising ideas using thorium as fuel, and fusion may someday be closer than "20 years away." Right now natural gas is extremely cheap, and it makes sense to build power plants that use it. 50 or 100 years from now it's likely that natural gas becomes expensive and we'll need something else. Solar and wind are way more expensive and a real problem to the grid because they are intermittent. They are also an environmental problem. They require a lot of otherwise pristine wilderness, use materials the mining of which are a big pollution problem (but in China, so who cares?) and windmills kill large numbers of eagles and bats. An order of magnitude leap in energy storage is needed before they should even be considered, and they need to find a way to keep birds and bats away from windmills. The ultimate future of humanity rests in space travel. Failure of NASA to even try to develop something other than chemical propulsion is another big disappointment.
