The environment is an evergreen topic, but as Earth Day approaches, AOL Search and Hitwise report on the Web's search for green.

The top searched-for terms on the portal include: recycling, global warming, endangered species and solar power. Hybrid cars came in as the fifth-highest searched for environmental term. While Earth Day may trigger a handful of these searches, overall, drivers are likely more eco-conscious due to the increase in gas prices.

Hitwise captured clickstream data across the Web to report on searches for Earth Day and other environment-related queries. Internet users who typed "Earth Day" into the search bar most often visited earthday.net, which earned a 19.01 percent market share. Earthsite.org, and earthday.wilderness.org followed second and third.

The EPA ranked seventh with a 5.3 percent market share in terms of searches for Earth Day, but a handful of other eco-minded queries routed visitors to EPA.gov. 'Global Warming,' 'EPA' and 'acid rain' garnered the most traffic to the site. A handful of searchers visited the EPA site for information on household issues such as 'old,' 'radon' and 'asbestos.'

The search term 'recycle' ranked ninth in terms of traffic to the EPA site, however Web users often search for recycling information to learn about how to dispose of recyclables. "Recycling" is the top recycling-related term, with 8.5 percent of searches. 'Recycling paper,' 'computer recycling' and 'paper recycling' are all common Internet search terms.
