I'll go first. 1. 1% rule (easy and so efficient)2.

I bought the building in June and will be looking to do a cash out refinance as soon as I can  to extract the ~45k I put into it and dump it into another project.I got a MassSave (energy savings program in Mass) audit done, and they quoted around ~10k for insulation.

You'll find that they look very similar inside and out so you can learn how to efficiently rehab them and repeat the process.  

Assuming that you’re not in the more rural parts of the county,  you are likely to be met with quite a bit of opposition if you attempt to erect a wind turbine large enough to supply energy for the whole home.As for the self-sustaining generator -I am no physicist, so I may be wrong, but it is my understanding that a completely self sustaining generator is theoretically impossible under the current laws of physics. 

Not an advocate of big gov, just do their jobs efficiently and enforce the rules evenly.     

I expect people to do things in an efficient and expedient manner because it is what I would do.

Unfortunately, the Sutton Power station ash ponds are significantly (5x to 6x) larger than the Dan River ash ponds according to NC DEQ Inventory of Duke Energy Coal Ash Ponds and Wilmington is significantly more populated than Eden NC, the site of the Dan River breach. 

in order to get those returns, i will need to get more efficient with rehab costs and such as well.  

We also have all high efficiency mechanicals, so the energy usage isn't much.The reason I asked about a garden is because invariably, green-minded tenants love to garden.

All this vigorous energy oozing out of my essence and there I was; splattering it around everything like a three year old kid frolicking around in a muddy rain puddle!
