Differentiate between product and issue, but the product is the issue.

Because we are not familiar with the issue we will quickly use Google and Wikipedia to get familiar with the topic.

Alternative search queries: solar power, solar energy. We changed our topic from solar panels to solar power because solar panels refer to a product and solar power is an issue. Michael notes that solar energy gives different results than solar panels. Solar energy gives more results in Google than solar power thus we agree upon solar energy. Shift from solar panels to solar power to solar energy. From physical object to issue.

1. Google

Top 10 results. Ten different results. Query: "global energy" (ToolCompareLists)

en.wikipedia.org/wiki/Solar_power http://www.ases.org/ http://www.canren.gc.ca/tech_appl/index.asp?CaId=5&PgId=121 http://www.eia.doe.gov/kids/energyfacts/sources/renewable/solar.html http://www.energyquest.ca.gov/story/chapter15.html http://www.history.rochester.edu/class/solar/solar.htm http://www.sciencedaily.com/news/matter_energy/solar_energy/ http://www.seia.org/ http://www.solarenergy.com/ http://www.solarenergy.org/

When we use ToolCompareLists to get the urls from the top ten Wikipedia is excluded. Probably because the url doesn't start with www but en.

Interesting: The third result in Google is a page for kids Scrape google's top 10 results for "global warming". Tool: ScrapeGoogle. Default settings. Copy paste top ten. note: add http:// to en.wikipedia.org/wiki/Solar_power
