Only if you care about short term return. In the long term, they are all cheaper.
I take it you are referring to the long term damage to Mother Gaia
, because the economics suck.
That's what we have enough existing fossil burning plants for.
You can't just flick on a switch and get a fossil fueled power plant to start up like a portable generator. It needs hours to wind up and wind down, which means it has to be running at close to normal output anyway in case wind and solar generation tail off. Fossil fueled power plants also run efficiently at constant output. Decrease and increase output like a car in city traffic and efficiency drops and "pollution" increases.
BTW, there's a difference between individual income and household income. Check it out.
Want to see a preview of what happens with the introduction of a CO2 tax? As Flying Binghi pointed out, look no further than California. The state is close to bankrupt and it has a business exodus for destinations east that rivals the gold rush to the region in 1849 (sarc).
Which country is going to be the first to leave the EU...Greece, France or Germany? Germany is refurbishing its coal generation program. It relied on PV and wind and is discontinuing nuclear, but the money is running out like water through a drainpipe and someone is starting to notice that unless they do something fast, there will be a desperate and dangerous shortage of power.
