If the govt offers reduced tax for particular types of ownership (eg non-profit organisation), then you could look at how you could use that as an option to make it easier.
The reality is that in most developed countries we need a certain minimum amount of money to do various basic things, such as own land. Many would consider that you are still getting the ...
If you're currently in Western Europe, then Eastern European countries may be very interesting for you to look at, because compared to Western Europe:
The cost of living tends to be lower, so you could invest more of your savings into alternative technologies such as solar energy
Cost of property tends to be lower (both housing and land)
There's generally ...
I can only tell you about my country, Chile, where I've been watching the situation closely. But since I'm living in France now (for the moment), I'm also familiar with the situation in France and Spain.
As things are in Chile right now, I believe that self-sufficiency is quite affordable. We can generate our own energy, our tax load is quite low (compared ...
Washington State recently implemented a new set of rules allowing greywater. Details: http://www.doh.wa.gov/CommunityandEnvironment/WastewaterManagement/GreywaterReuse.aspx
In my experience, greywater legislation is typically focused on plumbing and building codes, e.g. "Can I plumb my shower to drain in to the garden?" and not behavior, e.g. "can I take a ...
The Building Regulations for England, and the national (largely voluntary) Code for Sustainable Homes, cover water efficiency and greywater recycling. The calculation for legal compliance includes the ability to achieve compliance by increasing your energy efficiency through greywater recycling, so it is actively encouraged by the regulatory regime.
You have to persuade people to do it and ensure the infrastructure is there.
For the first, start an organisation of volunteers. Put up posters, organise lectures in schools, factories, social centres, do radio interviews... it takes time. Don't lose heart.
For the second lobby your local and national politicians, make sure everybody has access to ...
In the U.S., building permits are generally administered and controlled by the county. Contact your local county planning office to get more information on what their requirements are for solar. If you are really lucky, you may even find you are eligible for a rebate of some sort for going "green."
Science Daily is a good one. It discusses new scientific articles in a way that is understandable for non-scientists and it provides a link to the original article so you can read it yourself. The site has quite a bit of interesting subtopics. Just to name a few:
recycling and waste
Strawbale has established codes in many jurisdictions. Try the SB-R-US group on Yahoo groups for details. Note: 2 story bale is much dicier for standards.
Notably: California has a bale code that is accepted in active earthquake zones.
CMHC in Canada will loan money on bale houses, and has model codes
I've not heard of an earth shelter building that ...
It's very difficult to find any hard numbers. Countries that currently have the highest greywater usage are most likely countries with very poor water-supply systems (think Congo, Liberia, Palestine). These are also the countries that do not have the resources to keep track of things like this.
Alternatively, to get some indication of interest in greywater ...
