What are the advantages of a purpose build Tiny House versus a RV trailer versus a Mobile Home?
I have a friend who has made a very nice mobile Tiny House.
The reports I've read on the prices of these make them pretty dear. In many places for zoning reasons they have to still be nominally mobile.

European energy production figures and graphs
I'm interested in the breakdown of energy production by individual EU country.
For the EU I found this site, it's good, but it does not offer the kind of breakdown I'm interested in - I'd like to see it in the format of 'stacked, one country, at a…

Rough cost-benefit of stopping car to recycle batteries
I use up batteries (both recyclable and not) at an exceedingly slow rate. Stockpiling batteries for proper disposal is not realistic as I will do so for years, if not decades. All the more so, since I live in a very tiny place.

We've been considering getting a rain barrel, and I like the idea -- it doesn't make sense to just have the water run off into my yard creating a rut; I'd rather put it to good use.

I know that vermicompost needs to "breathe" as it has living matter within. I've tried in vain to find out what material I should use for packaging, as I need to ship (by truck, up to 1500 km, in a tropical climate) the compost to customers.
