Energy 101: Feedstocks for Biofuels and More

Nearly a billion dollars a day. That’s how much we spend on oil imports in the U.S. — oil that powers our nation’s transportation systems and industries. But here’s something to think about: a strong biofuels industry could meet much of our demand. Biofuels are made from organic materials, or biomass, grown in our own […]

Energy 101: Fuel Cell Technology

We all live in a modern world—a world full of technologies that looked completely futuristic just a generation ago. Those modern, futuristic devices that help get us through the day all use energy, and to supply all of that energy, we need fuel. Today, the technology around generating clean renewable energy is evolving about as […]

Energy 101: Marine and Hydrokinetic Energy

We all know energy can come from the wind and the sun, but there’s a plentiful renewable resource covering more than 75% of the planet that you might not have thought about: our water! The movement of the ocean’s waves, tides, and currents carries energy that can be harnessed and converted into electricity to power […]

Energy 101 | Algae-to-Fuels

We all need fuel to get around. And as America takes steps to improve our energy security, homegrown fuel sources are more important than ever. The Energy Department is researching one of the fuel sources of the future found here: in algae. Have a look at this algae farm. These large, man-made ponds are called […]

Is Geothermal Energy the Next Solar?

– Well, Kathy welcome to Teslanomics, I’m very excited to hear about your company, Dandelion. Is it just Dandelion or is it Dandelion Energy? How do you guys prefer it? – Our real name is Dandelion Energy, but many people just call us Dandelion. (upbeat music) – Hey guys, that was Kathy, the co-founder and […]

Energy 101: Energy Efficient Commercial Buildings

Here’s a fact that might surprise you. About 20% of all the energy we use in the U.S. goes to power commercial buildings. Buildings like the offices and schools we use every day. So you can easily see how much energy—and money—we can save when our buildings are as energy efficient as possible. Today’s energy-saving […]

Energy 101: Wind Turbines

MR. : We’ve all seen those creaky old windmills on farms, and although they may seem about as low-tech as you can get, those old windmills are the predecessors for new modern wind turbines that generate electricity. The same wind that used to pump water for cattle is now turning giant wind turbines to power […]

Energy 101: Geothermal Energy

YOU MAY HAVE RELAXED IN A NATURAL HOT SPRINGS POOL. OR SEEN THE OLD FAITHFUL GEYSER BLASTING HOT WATER INTO THE AIR IN YELLOWSTONE NATIONAL PARK. BUT HAVE YOU EVER THOUGHT OF WHERE ALL THAT HEAT COMES FROM? WELL, IT COMES FROM DEEP BENEATH THE SURFACE OF THE EARTH — AND IT’S CALLED GEOTHERMAL ENERGY… […]

Energy 101: Concentrating Solar Power

bjbj Take the natural heat from the sun, reflect it against a mirror, focus all of that heat on one area, send it through a power system, and you’ve got a renewable way of making electricity. It’s called concentrating solar power, or CSP. Now, there are many types of CSP technologies. Towers, dishes, linear mirrors, […]
