Just being curious: How many people here use green energy?
Do you have the possibility to choose at your place? Have you thought about it?
To give a definition: 'green' electricity, is sustainable electricity from environmentally friendly energy sources (i.e. hydroelectricity, solar energy, wind energy, wave power, geothermal energy, tidal power). Nuclear power is not included here because the problem of radioactive waste is a long, long way from sustainability.
I'm starting this poll with "Yes".
I'm not sure what 'green' electricity is other than a buzz word and marketing tool.
While I do prefer some of the alternative energy production methods you mentioned, none are what I would call 'sustainable.'
Hydroelectricity from dams (unless you're talking about micro-hydro, which would not be from a power company) has a large environmental impact. Not as much as fossil fuel use, but still not insignificant. My current work is stream restoration which we get most of our funding to improve fish habitat from power company mitigation. Dams disrupt fish migrations, change stream and river characteristics, disrupt the deposition of sediment (increasing erosion downstream), flood useable land (if we're talking about lost land due to other measures, this should definitely be included), let's not forget the materials and upkeep that go into the structures, and that's really only scratching the surface. Hydroelectric energy production is not sustainable.
Our current solar energy methods are also not sustainable. Solar panels have a finite life, materials have to be mined and processed (fossil fuels currently...), environmental impacts due to the area used for energy production, the loss of animal life (including humans), etc.
On top of that our current model of centralized power distribution. How much material, processing, and upkeep are required to keep the infrastructure up and running (all those cables coated in plastic running all over the place, on metal or wood poles?)
In short, energy production in total is currently not sustainable.
In my opinion, if we're really concerned about the environment (including humans), instead of 'feel good' measures and labels, we need to have a much better idea of the overall impact our lives and choices have on the world around us. We need more quantitative comparisons to honestly compare energy production methods (as well as many other choices we make). Move away from words like 'green' or 'sustainable' and discuss actual effects and data.
