Are there CO2 emissions from natural gas?
Until recently, natural gas was thought of as one of the cleanest fossil fuels. Yet new studies say it may be worse for the ozone layer than coal -- a fuel well-known for its harmful emissions.
Are we drilling for oil in the U.S.?
Chances are you've probably caught the latest headlines about off-shore drilling, but how much drilling is taking place on U.S. soil?
Beaming Down Earth's Energy From Space
It's always sunny in low-Earth orbit, so what better place to look for a source of solar energy?
Can hydrogen be the fuel of the future?
When it comes to looking to the energy source that will replace fossil fuels, there are no shortage of options.
Can we harvest the energy of lightning?
From corn to solar power, scientists have been searching every crevice of the Earth to find reliable sources of alternative energy. Could lightning be the answer?
Carbon Capture and the Storage Effects of Long-term Use
It's not news that we're spewing carbon dioxide into the atmosphere faster than the planet can deal with it. What is news, however, is that the futuristic technologies being tested to deal with all that CO2.
Can we harness energy from tornadoes and hurricanes?
Amid the deadly gusts of wind and chaotic storms signaling an impending tornado, you rush indoors to a safe place to escape harm's way. But is there a way to actually benefit from that destructive power?
Powering the U.S. with Earthquakes
Ever since the big quake swarm started in the Vanuatu area yesterday, I've been itching to do some number crunching to see how much energy the Earth is releasing through these underground ruptures.
Debunking The Perpetual Motion Myth: What is zero-point energy?
Imagine an energy source that was infinite, clean, and completely scalable. It would solve many of the world's problems -- and sounds too good to be true ... right?
Everglades Oil: What's to drill?
What many people consider a precious natural treasure and home to rare and endangered plants and animals – also sits atop an unknown amount of petroleum.
Geothermal Energy: Hot Times Ahead
Nowadays, geothermal power plants also take advantage of water heated by the Earth's interior to boil water into steam.
Could we harvest energy from earthquakes?
Fossil fuels, including coal, oil and natural gas, supply the bulk of the world's energy demand. Wind, the sun and nuclear energy are ascending sources of power worldwide. Could we tap into the power from earthquakes?
How can the moon give us clean energy?
A few decades ago, the pursuit of clean energy was "green." Now, it's a necessity. Not only is our power consumption propelling the human race toward a hot, watery, lonely end, but clean energy tends also to be renewable.
How can the ocean give us clean energy?
In the face of increasing energy demands and increasingly problematic energy sources, the appeal of using the ocean to generate power is obvious: Water covers more than 70 percent of the Earth's surface, and it's not going anywhere any time soon.
How do we get energy from natural gas?
You've heard the clean-fuel hype. So what's your role? Homeowners and residents account for 21 percent of all natural gas consumption in the U.S.
How do we use natural gas to meet our energy needs?
Natural gas is a major and essential part of the U.S. energy market, amounting to 25 percent of overall energy use and more than 20 percent of electrical production, according to the New York Times.
How does carbon capture work?
Jesse James, Billy the Kid, and Bonnie and Clyde have nothing on carbon. Do you know how carbon capture works?
How does carbon sequestration work?
Imagine blowing up balloons with your car's tailpipe and then burying those balloons where they'll never be seen again. If you can imagine that process, then you pretty much can imagine the processes of carbon capture and carbon sequestration.
How does drilling for oil in the Arctic work?
Like all offshore drilling, drilling in the Arctic is more costly, complicated, and politically controversial than drilling for oil on land.
How does natural gas drilling work?
When you switch on your furnace or turn on your gas stove and use the heat from that little blue flame, you’re doing what people in 62 million other American homes do every day, too: You're using natural gas.
How does solar power help the environment?
Our homes, vehicles and technologies require immense amounts of energy, yet fossil fuel supplies are finite. Sunshine, however, isn't disappearing anytime soon.
How have we improved oil rig technology?
When the technology in consumer goods like cell phones improves, we all know about it instantly, because we all use these gadgets. But truthfully, technological improvements in specialized equipment like oil rigs, is probably just as important, if not as reported.
How is gas extracted from shale?
Beneath the surface of a large portion of North America, buried in ancient bedrock, is a massive reserve of natural gas.
What is natural gas?
In any conversation about fuel and resource consumption, you're likely to hear at least a passing reference to natural gas. Some argue it could wean the modern world off of its dependence on oil and coal.
How is powdered activated carbon used?
The use of activated carbon is pretty straightforward: it boils down to combining infinitesimal grains of carbon with contaminated things you want decontaminated- water, air, metals or the human body.
