Man people make a big deal out of nothing. They need to learn how things work.

The world is more environmentally friendly in terms of energy, albeit still heavily leaning towards fossil fuels, because of one thing: economics. The price of solar and wind plummeted.

Just last week we had an article about a mining company converting their operations to hydro power. Guess what happened, their profits went through the roof since their energy costs were almost entirely eliminated.

Who is the big country for bitcoin mining? China. Who has the biggest jump in solar installations the last two years? China.

Even if the bitcoin code isnt changed to use less energy, with the advancement of renewable energies in terms of the cost, heavy power users are at the top of the list to switch. This group would include bitcoin miners. A couple years ago, it was google and facebook who were sucking all the energy the world had...now they are both nearing, if they havent attained, complete powering by renewables for all their servers.

Environmentally friendly? Yes...but it saves them a boatload of money.
