In February 2021, Tesla announced that it had purchased $1.5 billion in Bitcoin and planned to accept the cryptocurrency as payment, causing the price of Bitcoin to soar to record high numbers. However, three months later, Elon Musk disrupted the cryptocurrency market when he tweeted, “Tesla has suspended vehicle purchases using Bitcoin,” citing concerns about “rapidly increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel.” Overnight, the Bitcoin market dropped by almost 10 percent–so how founded are these environmental concerns in cryptocurrency mining, and could cryptocurrency have a clean energy future?Continue reading

Reading Time: 3 minutesMost of us are completely unaware of how the electricity we use is generated. We just put the plug in the outlet and forget about it. Unfortunately, this is one of those situations where ignorance is definitely not bliss! Understanding where your power originates is crucial in an energy efficiency standpoint.
For anyone wondering where their energy comes from, the chart above displays the sources of our power usage nationwide and can offer insight about output sources. No surprise: the decisions that determine this mix are made by your utility company with their best interests in mind. Sources are chosen on the basis of factors such as cost, availability, and reliability of supply. That’s how coal came to fuel almost half of the U.S.’s electrical needs. It’s cheap, it’s plentiful and it’s relatively easy to mine. What didn’t factor into the utility’s decision were things like the environmental impact of their choices–costs not borne by them but by you, me, and the communities in which we live. Nonetheless, the recent ITC extension and Paris Agreement are two reasons pointing to an approaching overthrowal of fossil fuels by the renewable industry. Continue reading
