Historically, most cars have run on gasoline, but that doesn't have to be the case in the future: other liquid fuels and electricity can also power cars. So what are the differences between these options? And which one's best? Dig into...

elon Musk discusses his new project digging tunnels under LA, the latest from Tesla and SpaceX and his motivation for building a future on Mars in conversation with TeD's Head Curator, Chris Anderson.

Although it’s not likely to happen soon, someday gas stations may be replaced by (or turn into) another type of fueling station, because no fuel or mode of transportation is forever

Even though they power many of our modern conveniences, batteries have a long history. Hank explains how and why these marvels work and what they've been used for over the past 2,000 years!

Entrepreneur Elon Musk is a man with many plans. The founder of PayPal, Tesla Motors and SpaceX sits down with TED curator Chris Anderson to share details about his visionary projects, which include a mass-marketed electric car, a solar...

Some people say that buying an electric car is a great way to fight climate change - but if they use electricity that is made by burning fossil fuels, are they really more environmentally friendly than gas powered cars?

If you've been in the market for a new car in the last couple years, you've probably at least considered an electric vehicle. But tracking all the pros and cons can be daunting, and it seems like there are new technological and policy...

Electric vehicles are not necessarily greener because they create no emissions. We have to take a look at the bigger picture. Source of electricity, depending on the fuel, can produce greenhouse gases. Manufacturing the components of the...
