The lobbying disclosure documents filed with Congress for the first quarter of 2009 show that lobbying spending has slowed or decreased at many large associations compared to the same period in 2008. 45% of the top 200 association/nonprofit lobbyists reported decreases in spending. However, renewable energy and environmental groups increased their lobbying expenditures, with the American Wind Energy Association spending over 2.5 times more and the Solar Energy Industries Association almost tripling their outlay. The U.S. Chamber of Commerce remained the top spender but the American Coalition for Clean Coal Electricity saw the biggest decrease, down 81% from last year.
