Everyone one of your points is entirely false.
1) No. Wind and solar vary with clouds and wind patterns and have no correlation to usage patterns. Renewables do not cut into anyone's profits, only natural gas does that with massive oversupply with lack of storage/transmission capability. In fact, renewables tend to be big profit cash cows for industries because of government subsidies that pay for them to build them, even when and where they don't work, and then they get to write off the losses from taxes. Why do you think there are so many idle wind power farms all over the country?
2) Renewables are also highly centralized in that they are totally dependent on federal government subsidies and all the cronyism and corruption that comes along with it. The rest of point two I won't even go into as it is just loony bullshit.
3) What do you think causes the cost overruns? Environmentalist protests and lawsuits. Nice catch 22 there.
