Earth Day may be once a year but Miller-McCune has been hard at work these many months chronicling solutions for various environmental problems, from how we power our homes, our cars and even what we wear.

Solar Building a Wise, and Ancient, Philosophy
The cheapest solar technology is just situating your home or office in the right direction when it’s built. You don't have to be Socrates to understand the concept -- but it might help. Full story

More Hype Equals Less Action on Climate Change
As Al Gore inaugurates an advertising campaign about the need to combat climate change, two new studies suggest that motivating the American public to take action will be a major challenge. Full story

Did Archimedes Solve Our Energy Crisis?
Sticking solar concentrators where the sun shines could potentially generate phenomenal amounts of electricity. But the perfect technology doesn't yet exist. Full story

Photovolltaics: A Bright Idea
Part one of three: Scientists have come up with a seemingly magical way of changing the sun's energy - not its heat - into electricity. They call the technology photovoltaics - the direct conversion of the sun's energy into electricity using solar cells thinner than a human hair. Full story

Solar Cells From Space to Earth
In the second part of our series on photovoltaics, John Perlin looks at how the in-space success of the world's first solar cell-powered satellite encouraged their commercialization across the globe. Full story

Electrifying the Developed World
In the final part of our series on photovoltaics, John Perlin explains how the German experience offers an excellent model for creating a solar cell marketplace. Full story

Nuclear's On the Road Again, But It's Uphill
Opposition in America to nuclear energy appears to be thawing and, though many concerns remain, the industry is gearing up to take advantage of this new willingness to reconsider nuclear power. Full story

A Really Inconvenient Truth
The climate problem can be solved. But tackling it is going to be a lot harder than you've been led to believe. Full story

Workhorse of the Solar Industry
When people think of solar these days, photovoltaics, or solar cells, pop into their heads. But there is just so much more than merely PV when it comes to solar devices. Full story

States' Action and Climate Change
Individual states are taking occasionally painful steps to rein in emissions. Full story

Changing Lanes
Next time you’re in the carpool lane, breezing past lines of traffic crawling along to your right, you might just want to hold that smirk of satisfaction: The advantages of the high-occupancy vehicle (HOV) system may be much more modest than you think. Full story

From Petri Dish to Gas Pump
In a comic book world, a superhero single-handedly addresses the ills of the world. Now imagine a simple organism simultaneously tackling three of Earth's nagging problems: air pollution, global warming and depletion of energy supply. Full story

Going With the Wind
The United States remains on the low end of countries using energy powered by wind. Experts point to tax credits as a factor in efforts to establish wind as an energy source. Full story

Small Wind, Big Business
The 2007 Farm Bill suggests tax credits as one way to offset the cost - as great as the environmental benefits - of small wind projects. Full story

How Climate Change Will Affect What We Wear
While scientists monitor how our clothing affects the climate, trend-watchers are more interested in the reverse: how climate change is beginning to alter our apparel. Bamboo underwear, anyone? Full story

Seeing the Rainforest for the Trees
While geographer Alan Grainger has upset conventional wisdom by suggesting the world's tropical forests are not shrinking, he sees his research as a clarion call. Full story

Hydro Doesn't Have to Be Big
In the first of a three-part series looking at the untapped potential for hydropower to supply the U.S. with carbon-free electricity, Lea-Rachel Kosnik finds ample opportunities for expanding hydro. Full story

Reducing Big Problem With Little Hydro Plants
Hydropower will never be the complete answer to emissions-free energy production in the U.S., but a strong case can be made for it becoming a useful part of the answer. Part two in a three-part series. Full story

Big Hydro Is Dead! Long Live Big Hydro!
Build new, low-impact hydropower facilities but keep the old: Large dams already in existence can be improved. Third of three parts. Full story

The Low Spark of High-Ideal Bulbs
Cleaning up a broken compact fluorescent bulb (and the toxic mercury inside) can turn any living room into a hazmat site. Full story

Good News -- and Bad -- for Coral Reefs
Reports show the ocean's unique ecosystems are adapting to fluctuation in water temperatures likely caused by global warming, but increasing acidic levels may prove fatal for the world's coral reefs. Full story

A Take on Earth's Temperature, Post-Bali
A roundup of research taken in the wake of the Bali summit on climate change finds little to warm the heart with the one exception that Atlantic hurricanes may grow more numerous but less fierce. Full story

Smokey's Legacy: Are Forests Contributing to Climate Change?
While it's widely acknowledged that forests can be useful for holding carbon, they release phenomenal amounts of greenhouse gases when they burn. Full story
