I met a young couple the other day who politely asked me about solar and wind, and the environmental problems they cause.

I responded that “there is no such thing as a free lunch.”  In other words, there are no energy-related processes that are 100% free of negative environmental consequences.

Nuclear comes as close as anything, and may eventually win the day, if the promise of fusion or the fission of thorium can be realized.

Until that day, if it comes at all, solar are wind are offsetting the consumption of fossil fuels, especially burning coal, which has horrific consequences to all life forms on this planet.
