Nuclear Power

I have a few questions about nuclear power and I couldn't get a straight answer from searching. The searches I've done were all old and apparently there may have been changes along the way.

I recently built a nuclear power corp and am wondering if it was a mistake.

1) Is it better to contract all the power towards my country? Just so my corporations won't have to buy from the market all the time. I read that it's always best to buy from the market, but wasn't sure about power.

2) Is that CO2 tax in effect from what I've read?

3) I noticed my nuclear power at 250 efficiency/quality keeps having an abundance of products. Even when I sell at 250 with 2% declination every month, it still won't sell the products.

Your help is much appreciated.

1) buy nuke power, it converts to EP and is cheaper even when in demand,
2) idk what the CO2 is...
3) best price for selling is good

Good suggestions.

there is no CO2 function yet.

Also,
I have seen many times, that there is a surplus of nuclear power and a shortage of electric power and the price difference is quite large. (EP is much more expensive).

So sell your nuclear power to your country, purchase more nuclear power from the market and then sell the surplus you have on the market.

in fact, you can continue doing so (buying NP and selling EP) and make a direct profit as long as there is a surplus of nuclear power.

Thanks guys, it's been a great profit strategy so far and I can finally break even with my ammo purchases.
