One of the biggest advantages renewable energy has over both nuclear and mega-dams is that the size of project required to achieve the commonly quoted LCOE (levelized cost of energy) is much, much smaller. 50 MW or perhaps less per site, versus 1000+ MW.

This means:

1. no mega projects that attract similarly sized public opposition

2. 1-2 year construction timelines instead of 10+

3. much, much less financial and regulatory risk

4. if an individual project goes off the rails because of bad management, it just gets cancelled instead of being pushed forward with endless public dollars because of sunk cost fallacies

The private sector is well able to stomach the risk level of wind and solar and finance and build it on their own, whereas nuclear and mega hydro essentially require government financial backing, which again contributes to the agency problem.

We know we can build 1,000s of MW of wind and solar per year in a safe and cost-effective way because we're already doing that. Every single nuclear or dam project in North America right now is a delayed, over-budget financial and project management boondoggle.
