This is true, the media is over exaggerating things here. Considering that there are many other human activities that are only wasting energy or much more intensive energy users. As bitcoin is relatively new to their grasp, they are finding loopholes on how to find faults on this new technology.
Because bitcoin threatens those in power. They don't care if industries such as video games or online pornography are orders of magnitude more wasteful than bitcoin. In fact, all the better! These are products we can tax and make a profit from, and so their environmental impact is irrelevant. But bitcoin comes along and is a direct threat to their monetary monopoly, so it gets disparaged with any little morsel of criticism blown way out of proportion.Because Elon brought it out to the attention of world and it reactive which showed how serous the matter is and for the best interests of mother earth, going green is the only way for a sustainable environment.
Ahh yes, Elon Musk, that great environmental campaigner who launched a car in to space on a rocket just for the lulz. 
People like to say that banks spend more energy, but what's the difference in scale? Any honest analysis must consider the scale.
Fiat is a few several hundred times worse according to this analysis, which is well worth a read: https://www.coindesk.com/whats-the-carbon-footprint-of-fiat-money. If bitcoin can become widespread enough to reduce the chances of the next global recession even a little bit, reduce its magnitude, or delay it, then bitcoin would become net carbon negative.Sorry to say that but renewable energy is still more expensive than conventional energy.
Not true. A few years ago, it became cheaper to build new renewables than it did to build new fossil fuel plants: https://www.forbes.com/sites/jamesellsmoor/2019/06/15/renewable-energy-is-now-the-cheapest-option-even-without-subsidies/And a report from last month shows that it is starting to become cheaper to build new renewables from scratch than it is to even continue to operate already exist fossil fuel plants: https://www.renewableenergyworld.com/solar/report-its-now-cheaper-to-build-new-solar-than-to-run-existing-coal-plants-in-china-india-and-most-of-europe/
