In my life outside of DGB, I work on environmental issues, questions, and problems.  I am deeply engaged and aware of the problems caused by anthropocentric impacts on the non-human ecosystems.  I have a really long reply to the question about if POS is more environmentally friendly than POW.  I'll finish typing it up in the next couple of days and post it somewhere (although not here because it's too long and detailed).

The short version is that yes, POS uses less electricity than POW.  However, making the argument that because it uses less electricity it is necessarily more environmentally friendly is not always true.  That claim requires making assumptions that ignore inputs, outputs, and how the use impacts the larger system it is a part of.

I advocate ASICs partly precisely because they are so much more power efficient and environmentally friendly.  I use my mining equipment to heat my house.  it's not a very big house so I haven't had to turn on my furnace since 2013.  But even if it were bigger, heating just a part of the house would offset the power and fuel for heating.  I don't mine in the summer (I only mine when I need to heat the house).  My mining equipment uses about the exact same electricity as the furnace.  So, there is no additional environmental impact - the electricity used for the mining equipment is roughly the same as the electricty used for the furnance; in fact, there is net environmental benefit because I'm not burning natural gas (my furnace burns natural gas for the heat but the compressor uses electricity to push the air).  Because of restrictions in the community where I live, I cannot install solar or wind-powered home electricity.  However, a substantial portion of my electricity comes from a commercial wind-farm. I know that Jumbley used a home wind turbine to power some of his mining equipment for a while.  I'm working on a solution that allows me to mine all year ... and I hope to have it done by the coming summer.

It's a really interesting question ... and I agree 100% that DigiByte should work toward advocating for positive environmental impacts of our network.
