I have to write a report comparing and contrasting 3 types of renewable energy sources. One of my chosen ones is already geothermal, can you give me two more renewable energy sources that are considered the best ones? Because I have to choose which one is the best and explain why it is.
Thanks.
By the way if you can, make sure it’s a good source for CANADA.

I’m writing a report for school on the future of renewable energy (including wind, water, solar, geothermal, and biofuel), and want to give some real world examples of how renewable energy is being used effectively today. What strikes you as some of the best real world examples you’ve seen or heard of?
