Reblogged from Saving humans:
The blog posts this week have raised a series of questions about energy security. Conventional political thinking on energy security has a narrow focus which emphasises the need to secure state energy supplies. Sustainability is largely ignored, as short-term economic benefit is continually prioritised. The political and military survival of states is prioritised over environmental or climate stability, and human security. So what is to be done?
Discussions of energy security are slowly beginning to notice the need to factor in climate impacts in economic and human net-benefit calculations, with the IEA releasing a special report in 2013 to map out what can be done. Improving energy efficiency is central, as is continued and increased investment in renewable energy. Some present nuclear energy or clean coal technologies as part of the solution, but a recent study by Mark Jacobson examined solutions to global warming, air pollution and energy security and took the three as linked, and he found that clean coal technologies and nuclear investments provided ‘less benefit with greater negative impacts’. The conclusion of the study stated that ‘because sufficient clean natural resources (e.g. , wind, sunlight, hot water, ocean energy, gravitational energy) exists to power all energy for the world…the diversion of attention to the less efficient or non-efficient options represents an opportunity cost that delays solutions to climate and air pollution health problems’.
Organisations like Greenpeace and Friends of the Earth have also produced extensive reports outlining alternative policy solutions to enable the world to move away from fossil fuels towards a sustainable future. Whichever solution is suggested, it is likely to require a serious change in thinking on behalf of political leaders. Economist Tim Jackson suggests that rethinking notions of prosperity and growth are central to solving the issue. To minimise permanent or long-term climate and ecosystem damage, it is clear that sustainability needs to be prioritised over short-term economic gain. The truth is that we simply do not know the extent of the damage we have already caused the planet, and to save the future of humanity, any further damage needs to be avoided.
