Wind energy is great, but what happens when there's no breeze? The Iowa Stored Energy Park will store compressed air underground. Can it replace traditional energy sources?

Protecting the Earth is serious business for a radical group of environmental and animal activists dubbed eco-terrorists. Who are they? Why does the FBI consider them a top priority?

You don't have to think too hard to come up with a long list of candidates for this title, but one far-reaching environmental catastrophe stands above the others.

Scientists are stockpiling the world's seeds, organizing them in giant libraries of planting possibilities. Is every type of plant included? Or, are the seeds of pesky plants shunned?

You might think of solar panels as large racks of rigid panels on someone's roof, but newer solar cells are more flexible and efficient.

Why waste drinkable water on your yard when your old bathwater will suffice? That's the idea behind gray water reclamation -- getting the most out of your water through reuse.

A sustainable community might not be as radical as you think. What's so crazy about minimizing waste, reducing consumption and preserving green space?

You've finally cleaned out your garage. Four cans of paint, a dead car battery and a circa 1991 Nintendo sit before you. But where in the world do you recycle these items?

Popeye used the iron from spinach to morph into a formidable sailor. We know that iron is an essential component of the human body. But could it also be the answer to global warming?

How will Abu Dhabi's Masdar City function without cars, skyscrapers and fossil fuels? How is such a city even possible -- and what will keep it running?

Do you want to go on a volunteer vacation where you observe grey whales and save the world? The nonprofit organization Earthwatch sends volunteers like you to assist scientists on expeditions all around the world.

Polar bears are facing a grim future as global warming melts their Arctic home. What problems are they up against and what's being done to save them?

Not all recycling is created equal. Some familiar recycled items are more "worth it" than others, and the hands-down winner may be in your recycling bin right now.

One company's SkyMine technology aims to capture industrial carbon dioxide emissions and turn them into an endlessly useful product: Baking soda. But how do pollutants become a household staple?

Thousands of women around the world choose to combat ecological problems -- they're known as ecofeminists. But what would you do if you found out your house sat atop a toxic waste dump?

No one likes paying bills. But you wouldn't have quite so many if you lived off the grid. How do you create enough energy to ditch public utilities?

Carbon dioxide released from burning fossil fuels is a prime suspect in global warming. Could we mitigate the problem by burying the CO2 deep within the ocean?

Right now, landfills are all over the place. Yet, no one wants to live near one. So, what if we combined all of those landfills into one? How much space would it take up?
