Mister has not, yet, installed solar panels on our home. We, unfortunately, do not have the right exposure.
I have not ridden my bike to work more often. The real estate thing kep me from doing it at all last summer and fall. I had to be available with my vehicle most days. (excuses, excuses)
We do not yet have a solar vehicle. Mister either want to build one - we don't have a garage for him to do that in, at present and Mister refuses to buy into what he terms the ugly and ridiculous electric cars which have been mass produced to date. Electric cars do not have to be ugly i.e. check out the Tesla Roadster. 
They also don't need to be that expensive. We're just waiting until its viable.
Anyway.
What have we done? Well, I've become rather anal and bring home anything from the office that can be recycled but not from the office. For example, plastic bags can not be put into the regular recycling, I bring them home and we include them with our bags which are returned to the grocery. I've also done this with old plastic food containers and lids from the office that would have ended up in the land fill.
We did, just last weekend, and when I say we, I mean Mister, anyway... we installed a wood stove into our home. We loved the one at my other house so much, now we have one too. Mister brings home construction materials (wood) from his work sites that would be recycled (so they say) but we take it and use it as fuel. You know, palettes and 2x4 ends, etc. I guess a lot of construction guys scavenge for stuff on job sites that would end up basically garbage and reuse it somehow.
Mister has pretty much removed all non-native vegetation from the back yard - with the exception of my tulips and a very few other plants. Our goal is to attract native bees and bugs and birds.
We have Mason Bee boards up hoping for native bees to come live with us.
They are far more gentle than ordinary honey bees and apparently are native to the region.
We've put up some natural bird houses. No birds living there yet, but that could be because there are tons of cats, including ours, in the neighborhood.
Mister and I commute together, when we can.
We have a compost bin and put all our vegetable scraps there for future use in garden beds.
That is all I have for now. We are doing what we can and always searching for new things to add to our palette.
I hope you all have a good day today. My thoughts are with you.
