You're forgetting the most important part of climate change - the way humans have changed the surface of the earth. For example, where I live, the natural vegetation is forest. It's now acres of corn fields/cover crops with irrigation. This allows extra water vapor low to the ground and in the winter when it snows, it makes the ground reflect more radiation than a forest would - making the record lows lower. (in addition to making it hotter in the summer)
Then take into account urban areas...
Solar holds energy from the sun which will still make the earth warmer, wind farms will change how energy is distributing.... So while not as bad, huge energy demand is going to change the climate.
While albedo change due to land use is important, CO2 dominates the forcings. Cleared land tends to reflect more heat than forests do but the CO2 release more than makes up for it.
The presence of cities and wind turbines can affect local climates but don't change much globally in the long run. Solar power also doesn't necessarily affect much either as a joule that is absorbed by the panel will eventually be released as heat one way or another.
