Renewable energy can't get much more mainstream than this—J.P. Morgan officials say the bank will facilitate $200 billion in clean energy financing by 2025.

In 2015, the bank facilitated around $15 billion in clean energy financing, so this pledge would increase that to $22 billion annually.

In addition, J.P. Morgan pledged to power its own operations entirely by renewable sources by 2020.
