Here's for one of them:
Type: Nuclear
Extraction: Uranium (the fuel for nuclear energy) is typically mined using open pit or sub-surface mining. Australia, Canada, Kazakhstan are where the world's largest deposits are.
Benefits: Low cost (if you don't count building the power plant), reliable (unlike wind & solar energy which comes and goes, nuclear is readily available), no carbon emissions, produce more energy than coal power plants (most popular energy source), no air pollutants emitted (all other nonrenewable sources, aka. coal, oil, and natural gas, release harmful air pollutants)
Risks to environment: Radioactive wastes require to be safely secured away for thousands of years before they can reach safe levels, nuclear accidents can happen, mining uranium cause land disturbance, thermal pollution in nearby bodies of water or wherever cooling water is released (this can lead to dissolved oxygen levels decreasing in that body of water which can suffocate aquatic life)
Other info: Nuclear energy makes up 10% of the world's energy consumption.
