1) buy coal from the trade market so your cities get powered (you should transition to 1 nuclear power soon since it powers up to 2000)
2) it's better to focus on one type of raw and stack as much of that mine as possible so you get a production bonus (the maximum is 10)
3) your city has 800 infrastructure, so you will need to have 2 coal power plants to power it (each coal power plants powers up to 500)
4) use the other remaining slots you have on military (if your alliance allows you to raid, go for it and you can get money and resources that way π)
5) hope this will be helpful! π
