The non-renewable alternatives like birning coal and wood, and nuclear fission all come with worse issues.
Coal is putting mercury into the environment which is toxic and causes serious birth defects because its pro-oxidant and uses up glutathione. Nuclear fission puts nuclear waste and a high risk of nuclear meltdowns should we have a Coronal Mass Ejection hit us, something that almost happened in 2012. Had that flare hit the Earth, its entirely possible we would have had (in addition to having very large and long lived losses of power, we might also have had to deal with multiple nuclear meltdowns as nuclear power plants, deprived of power to cool their cores, experiences something called “loss of the ultimate heatsink” in unison.
There is a very serious, substanial risk, we don’t have a large enough sample of data to estimate it because records of subspots and solar flares only date back a very short amount of time, and its only been just the last few decades that we have been vulnerable to this problem, and most of that time we’ve been unaware of this specific vunerability. But we do know its very high. Especially in partsof the US like the Northeast where geology makes the DC pulses that occur more severe.
We now know that a solar storm like the one in 1859, if it occurred today, might be a world and civilization changing event, with permanent repercussions and large amounts of human suffering.
We need to deal with it and pull back on things like nucleaar fision power which seems particularly problematic if it is as it is today. Apart from the nuclear waste and the necessity of cooling it, we need other forms of power that dont require a grid, and long distance transmission, which is where the DC pulses cause problems. Otherwise we could wake up one day without electricity and it might take a very long time to get power back - we just dont know. But there is no reason to think otherwise.
If many nuclear power plants lost cooling capability during that extended power outage, some or maybe even many of them might meltdown with long term repercussions. Large areas could become unsafe and uninhabitable for extended periods of time.
Corporations are consistently irresponsible when faced with challenges of this kind, it would be a situation thats not conducive to rational thinking or good government.
