Solar, Wind, or Water Power: What is your green energy source?

From solar to aquatic, what are your forms of renewable energy? Any new ideas? I know another post in the "Green" topic talked about a gravity-powered LED lamp. What next?

Kiteman has rightly said, "The key to renewables is to run a wide mix of resources". Also quote from WilliamB3 : "How do you eat an elephant? One bite at a time".

I am on the way to turn my home running on renewable energy. I have started with a medium sized biogas digester and presently using garden weeds to produce bio-fuel which supports 25% of our cooking needs almost free of cost other than a little bit of electricity I use for this. My garden gets weeded out regularly, we get Biogas and organic compost from the digested slurry. You can see both my instructables here at these links:

My next targets are power from sun and wind

I made this instructable on Solar+Wind house

I have 2k watts of solar panels, 2 large water heating solar panels and 3 cars that run on biodiesel.

Adding multiple sources into a system is definitely a good idea. I like solar panels for passive electric generation, and thermoelectric generators for active electric generation. Likewise, I like solar water heaters for passive water heating and rocket stoves for active water heating. In my area, I get a lot of sunlight for solar applications and I have access to wood and biomass and trash to fuel my rocket stove.

I intend to add a homemade windmill as yet another passive electric generator. As time goes by, I'll keep expanding my small system until it meets all my energy needs.

How do you eat an elephant? One bite at a time. Take that first bite and buy or build something to generate energy. It probably will not meet all your needs right off the bat, but if you keep adding to it as money and time allow, it will eventually meet all your needs.

Harvesting static electricity also has a lot of potential. Tesla knew this way back when. We have some catching up to do, but folks are experimenting again and I'm hopeful we'll figure out how to harness it.

I think it'd be a better question to ask is "which green energy generation process, or processes, fit my needs?".

Like Kiteman said, a mix is better then a single stand alone, and that's because diversity in generation of power makes for systems that are less susceptible to change.

To illustrate a bit more of what i mean, I lived in Utah until very recently. Utah is a great place for many green energy production methods, but Wave and deep ocean current are probably not the best options for people looking to produce power. The ocean is too far away, and water tends to not be reliably in the same place there (it's too dry).

That all said, something newish.... I'm mildly interested in using antenna to grab radio waves out of the air to produce power.
The orbit and rotation of the earth naturally produces radiowaves, so grabbing them seems reasonable (not violating any thermodynamics...).
Crystal radio sets, which run off of the ambient radiowaves, use tuned circuits to single in on a particular frequency; crystal radio sets can generate up to a single volt, depending on the quality of the ground you're using, and if they were untuned, they might be able to snag more electricity, though it depends on the interference of the circuit (i'm not an electrical engineer...).

So... if you want yet another way to make electricity, there's that.

Wave, biomass, geothermal, harvesting waste heat, landfill methane, tidal, deep-ocean current...

The key to renewables is to run a wide mix of resources.
