With climate change looming, it seems so completely backwards to go back to using it again.
Is it coal miners pushing to keep their jobs? Fear of nuclear power? Is purely politically motivated, or are there genuinely people who believe coal is clean?
Edit, I will admit I was ignorant to the usage of coal nowadays.
Now I’m more depressed than when I posted this
We don’t choose to build it more expensive than it needs to be. It’s by nature always going to be more expensive to build one of something instead of what the cost per unit is going to be when you make many.
Wind and solar isn’t going to solve the issue untill we come up with a way to store energy on large scale. When you plug in an appliance that electricity is not taken from a reserve but it’s produced for you in real time. Wind doesn’t blow and sun doesn’t shine according to how much electricity is needed at each moment. Finland produces all its electricity basically by hydro, wind and nuclear power. When it’s windy we have excess electricity and the prices drops to negative and we got to sell it abroad but when it’s calm the opposite is true. This wouldn’t be the case if we could somehow store that excess energy.
We’re talking about effective cost of the resulting power, altogether. All things included. (Except for nuclear waste, which is a topic for a different discussion and difficult to quantify.) Just comparing one aspect wouldn’t be fair.
Yeah, and science and investors are way ahead of politics. There are several concepts already available or already in place somewhere. Several promising ideas and projects that need funding. Storage facilities that aren’t able to store energy because Bavaria is not willing to run cables across the country. It is a complex topic that also needs individual solutions. For example depending on geography you could have dams and pump water. Or one of the concepts that work everywhere. Infrastructure and cunsumer get more advanced/intelligent. You could charge your car automatically during periods where renewable is abundant. You can fine-tune factories, maybe have the large heat pump of an office building vary temperature a bit when there is a Dunkelflaute. Some countries just get geothermal power for free because of their location… You can put those storage facilities close to energy generation or close to the consumer. And as supply and demand changes prices, it’s also well aligned with the way our economy (and capitalism) works.
We should really hurry up and put in the effort this needs. Because we really need those storage facilities. And I’d like energy costs to come down again, and CO2 emissions also.
And if I remember correctly, the current natural gas power plants are the ones that can react to supply and demand the most quickly. But this seems not to be a good idea anymore, now that we have enough problems with the natural gas in central europe. I (personally) would be happy if there was an alternative.
I haven’t heard any scientist in the last years tell something different from renewable plus storage is the way. Not unless some miracle happens and we get fusion reactors or something. But it’s still unclear it that’s going to happen.
