BP doesn't spend all its time exploring for oil and gas. BP Alternative Energy North America comprises BP's solar, wind, biofuels, hydrogen power, and carbon capture and storage (CCS) businesses. The division has invested $4 billion exploring for new technologies and operations outside oil and gas since it was created in 2005. While BP Solar went out of business in late 2011, BP Wind Energy owns and operates eight wind farms in the US, and BP Biofuels has interests in biofuel and ethanol plants in Brazil, the UK, and the US. BP Alternative Energy also provides venture capital to startup firms. Because of its investment activities, alternative energy represents less than 1% of BP's total revenues.
