Could Bitcoin cost us our clean energy future?

Gone are the days when it was just a currency for geeks. 2017 was without a doubt the year of the ubiquitous Bitcoin. In the past year, investors have flocked to the highly volatile currency seeking to make a fortune. It's attractive for several reasons: Bitcoin requires no central bank and is directly and anonymously traded from person to person. But its surge in popularity could have a real impact on the environment. We take a closer look.

While it’s a virtual currency, Bitcoin requires real energy, and lots of it. Today, each transaction requires the same amount of electricity used to power at least four homes in the United States for one day. Could Bitcoin end up being a threat to our planet? Join us as we explore why the currency is so energy-hungry.
