On July 21, the Sierra Club's campaign to fight coal-fired power plants received a $50 million donation from Bloomberg Philanthropies, which it will use to expand its Beyond Coal Campaign to persuade industry to abandon coal-fired plants and move toward more renewable energy sources. The Sierra Club is pushing the United States to retire one-third of the nation's coal-fired power plants by 2020, and the $50 million pledge will fund a significant portion of the 4-year, $150 million campaign and expand its current 15-state campaign to 45 states.
