SVN 1053 - Solar plant - Needs desert tile in city bounds.
Small bug, it will replace Coal, Oil, Hydro and Nuclear plants. (Note same on Nuclear power plant replacement, and Hydro replacement)
But if you have say a coal plant in the city, it won't list it as being replaced.
If you have a Hydro plant, the Hydro plant wont' be listed then.
Etc for nuclear/oil plants.
2nd bug on this, if you build the 3 gorges dam for the continent, Solar plant still comes up as an available build, even though it won't replace the 3 Gorges dam wonder.
On the 3 Gorges dam, when you build this wonder, all the cities on the continent, still retain their Coal, Oil, Nuclear and Hydro plants with any associated

for having that power plant.
Building the 3 Gorges dam should REMOVE these building from the city, and only provide power, with its associated

for having power.
2nd Bug Geothermal event not replacing power plants.
I received the Geothermal event, on a 1 city Island, I took the power option, but it hasn't replaced the Coal plant, only the -4

from having power from coal. I still have the option to build a nuclear plant, and by default a hydro if I had a river, and solar if I had a desert tile.
This event SHOULD remove all power options, and building built, as its been replaced by 'green' and 'clean' geothermal power.
