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.

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.
