I'll flip the question:
Considering that coal has provided a very significant amount of the electrical power and heat for humans over the past 100 years, how many lives has coal saved? How much has it improved the human experience?
Put simply, a world without coal is a horrible world.
- JoeAltmaier 12y agoWell, temper that with a view of a world where coal was scarcer, more expensive. It would not have been used for so many purposes, we'd have been more efficient in our spoiling of the planet. Being as cheap as it was, led to a car for every garage, consumerism, inefficient insulation in houses for the first century etc.
- strictnein 12y agoYou would prefer a world where only the rich can afford electricity and warmth? Because that's the world you describe.
- JoeAltmaier 12y agoOh don't be a pedant. If coal were more expensive, it would be used for important things - not pissed away. That says little about rich vs poor.
- strictnein 12y agoI'm not being a pedant. Where does the inexpensive electricity come from? It is very much about rich and poor. And making electricity is a very important thing.
- Retric 12y agoCoal is currently important, but not that important. As a finite resource it's also going to be gone in ~2 thousand years (big error bars on that though) which is a fairly short time period all things considered. For perspective let's ignore all non-renewables + wind and solar and just look at Hydropower. Hydropower use reached a record 3,427 terawatt-hours, or about 16.1 percent of global electricity consumption. That on its own is enough to provide useful power to everyone sure we would not be using it for home heating but lighting, computers, and refrigeration would easily make the cut even if AC would be far too expensive for most people. aka, most people get a setback but not to the dark ages. Toss in just wind power and you could meet the world’s electricity needs at perhaps a 10-30% increase in electricity costs. In the end there is a huge inertia in the current system; dropping coal in say 10 years would be possible, but ridiculously expensive. Dropping it over the next 100 might just happen without anyone noticing. PS: Solar is really interesting as it's cheaper than coal in some areas, but inertia and changes in the supply curve are keeping their prices linked. We are heading to a supply shift so peak costs might actually start taking place at night.
- _broody 12y agoThat's a moot point if there's another viable way to generate the same amount of power without trading lives in the process. Slave labor also improved your life quite a bit, provided you were a slave owner. Thankfully we found an alternative.
- strictnein 12y agoSlavery, really? That's your analogy? What's your viable way to replace coal today? Include explanations of how your replacement can be as reliable as coal, and how the developing world can afford these sources without sacrificing other government services.
- sigmar 12y agoDon't know where you have been, but coal use has decreased the past few years. Natural gas and renewables have already started to replace coal. http://en.wikipedia.org/wiki/Coal_power_in_the_United_States#mediaviewer/File:US_Electrical_Generation_1949-2011.png http://en.wikipedia.org/wiki/Coal_power_in_the_United_States...
- strictnein 12y agoThat's just the US, where natural gas is plentiful and very cheap.
- sigmar 12y agowell, the article is exclusively about the US. If you are up for talking about other countries, let's discuss France's coal power
- anon1385 12y agoLiterally millions of people are being killed by coal, without any choice in the matter[1]. What analogy would you prefer to use for something as devastating as that? Coal only seems affordable if the significant health and environmental costs are (incorrectly) assumed to be zero. [1] http://www.theguardian.com/environment/2013/dec/12/china-coal-emissions-smog-deaths http://www.theguardian.com/environment/2013/dec/12/china-coa... >Emissions from coal plants in China were responsible for a quarter of a million premature deaths in 2011 and are damaging the health of hundreds of thousands of Chinese children, according to a new study.
- Symmetry 12y agoI have no doubt that 19th century London was better off with coal despite the horrific air pollution it caused. But the question before us is whether to continue using coal now that we are much richer and have many more options in terms of what technologies we have.
- mikeash 12y agoThe proper solution is to capture the externalities imposed by coal and force those who burn coal to pay the entire cost of burning it, including the cost of the emitted pollution. Then the solution will work itself out. If coal is indeed the best solution even with all the damage it causes, it will still be viable when these costs are captured. If other methods are better, then they will win out. The problem is that right now we allow people to burn coal and vent the combustion products into the atmosphere while not paying for the massive costs this imposes on the general population.
- tsotha 12y agoThat's nice in theory, but the problem is nobody has any idea how to quantify those externalities.
- ghouse 12y agoThe same could have once been said about Whale Oil.
