Okay, I don’t think anyone’s taken this seriously yet, so…
How about, hydro-electric, geothermal steam, wind turbines, augmentative passive solar, such as water heating and daylighting (somwhat different then solar lighting, or skylighting, although skylights count.) Also let’s not forget rain harvesting, and gray-water usage.these save water, and energy from a treatment, billing, delivery standpoint.
Now that I asnwered the name other part: challenges, what happens when there is no sun/wind/water-flowing, if you have all of these, it won’t happen that often, but when it does, are batteries a practical solution? Won’t they eventually wind up in land-fill off-gasing? If you only use one or two of the 3 majors, what about when any of those aren’t available? Availability is still a big concern, hopefully that will be the next stock-market bubble and drive a massive influx of green-products.
The common challenges with non-renewables, rather than starting from an environmental standpoint, how about we start with what they’re called. NON-RENEWABLE, eventually we will run out. It’s theorized that we’ve found all oil on earth, and will start a downward turn on production by somtime in 2008 or 2009. Aside from that, there’s the obvious global warming issues.
O hope this helps some.

why do you ask questions you all ready know the answer to?
renewable resource = methane
non renewable=oil
blah, blah, blah, blah,
the real question should be why is it we don’t want to change our lifestyles to adjust to the crippling disaster we are creating for our children and our children’s children

solar: Its free ‘after’ you pay for a 20,000$ piece of panel and then you have matenince. Then what do you do when it rains?
wind: Its a GIANT SPINNING BLADE!!! So sometimes birds die. About 4000 a year world wide.
hydrogen: Clean fuel in, drinkable waste out.
lithium: The lithum battery life has ben multiplied x10. So yay.
At the rate the world uses it, gas will be depleted in 100 years. However cheap gas prolly won’t last anothr week.
But we can now turn turkys into thir weight in oil in 1 week with some time travel doo-hicky.
