Electricity is such an important part of our lives. here in Quebec most of our power comes from hydro-electricity, from rivers that have been dammed. Although less polluting than coal-fired plants and less dangerous than nuclear plants, nothing has zero imprint on the environment. Even wind turbines have an impact, killing birds and bats. So what is the solution? We have to learn to turn off what we don't need, to rely less on electronics for our amusement. I am not suggesting giving up these things, as I type this on an electronic device and then plan to enjoy the posts of others. Just use less that's the challenge.
