Energy giant BP says it has made its largest oil and gas discovery this century as it shifts its focus away from renewable energy and back to fossil fuels. The UK-based firm said on Monday that it is conducting tests at the site in deep water off Brazil's west coast.

British Petroleum (BP) claims to have made its largest oil and natural gas discovery in 25 years off the coast of Brazil. The discovery comes as the British oil major moves away from renewable energy and refocuses on fossil fuels and hydrocarbons.
