Sierra Club, NRDC Sue Feds To Stop Big California Solar Power Project. The same idiots who tell us we must use solar to reduce pollution sue to stop solar installation. The Sierra Club, the Natural Resources Defense Council and Defenders of Wildlife seem to fit the term oxymoron, especially the moron part. The result will no doubt be that the cost of solar power in California will increase. After the cost of this is factored in the ratepayers will no doubt get to bend over, which is fast becoming the official state sport of California.
