One of the biggest hurdles green energy faces is storage. While it's true that the sun, the wind, and the tide all produce force we can harness to create electricity, we don't live our lives according to these environmental factors.
Recycling is not a concept one usually associates with rocket launches. When rockets take off from the pad, each stage flies until it runs out of fuel, and then it is discarded into the ocean.
Everyone loves a barbecue. Whether it's a 4th of July outing or a family get-together, we all love the taste of fresh, flame-grilled food.
We have seen an energy revolution over the past decade and change. Green energy, which was once considered a pipe dream, has become an everyday occurrence.
We're all familiar with ethanol. It's a kind of alcohol that's used as a fuel additive that helps us pay less at the pump, and it can even be used as a fuel source on its own.
Chewing gum may not be the most prevalent form of solid waste in terms of volume, but it is one of the most annoying. Most people have had the experience of finding gum sticking to the bottom of their shoes and having to pry it loose.
One of the more vexing problems in waste disposal is the proliferation of plastic. Plastic, unless it is specially treated to be biodegradable, tends to last an awfully long time, whether it is disposed of in landfills or waterways.
Lithium-ion batteries have become ubiquitous as smartphones and tablets proliferate. These kinds of batteries are rechargeable, but not forever.
We've known for some time that big business is going to be a leader in adopting sustainable, clean energy. With Microsoft arranging to buy its energy from renewable power plants, and companies like Chevrolet and Nissan experimenting with their car batteries to run entire buildings on nothing buy solar power, we're starting to see that green energy isn't just good for the planet; it's good for business.
One of the biggest environmental concerns we face today is an overabundance of greenhouse gases in our atmosphere. These gases come from everywhere; it seems, but some of the major sources are burning fossil fuels, waste dumps, and heavy industry.
