Energy 101: Where Electricity Comes From

Where do we get the fuel we burn that powers our electric grid? Millions of years ago plants absorb the sun’s energy. When they died they were eventually buried under the surface. Under the Earth’s immense heat and pressure over millions of years, the stored solar energy intensified resulting in a set of energy dense […]

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: 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: 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, […]

Energy 101: Solar PV

MR. : All right, we all know that the sun’s energy creates heat and light. But it can also be converted to make electricity, and lots of it. One technology is called solar photovoltaics or PV for short. You’ve probably seen PV panels around for years, but recent advancements have greatly improved their efficiency and […]
