if you want to live in a modern society then you will have to accept that we will have to do some sort of pollution to get energy.. and when it's all added up it will be a lot of pollution

coal, gas, oil and other fossil fuels are easy to figure out how they pollute.

nuclear - radioactive materials have to be stores somewhere for a few thousand years.

hydro - cannot be placed just anywhere.

solar - require the creation of solar cells that require alot of energy and pollution to create. they can also be broken easily in bad weather. On top of all of it they require batteries that are full of toxic chemicals. Requires huge tracks of land and dozens or hundreds of units to provide for a community, likely taking away from farmland or animal habitat

wind - the wind doesn't always blow. also requires huge tracks of land and dozens if not hundreds of units to provide for a community, likely taking away from farmland or animal habitat

so take your pick. if you like your modern lifestyle then stop whining about hurting the environment. if you don't care about living modern you can get a log cabin in the woods and hide from the world.
