The following video is part of our "Motley Fool Conversations" series, in which advisor James Early and senior technology analyst Eric Bleeker discuss topics across the investing world.

In today's edition, James discusses an area of investing that socially responsible investors should avoid: mountain top removal. While the U.S. energy grid is very reliant on coal, this particular form of mining has a series of negative environmental ramifications. If socially responsible investing is important to you, James recommends avoiding Massey Energy (now owned by Alpha Natural Resources), Arch Coal, and James River Coal, and getting energy exposure instead with a natural gas company like Spectra Energy.

Editor's note: The following video incorrectly claims that Peabody Energy engages in mountaintop mining. The Fool regrets the error.
