Oil - it's bad. Most people would agree drilling for oil and removing fossil fuels from the ground is a bad thing for the environment, now this goes deeper (excuse the pun), if we are to save the environment we should live in a sustainable way - which includes photovoltaic panels, solar panels, wind farms, generating electricity from tides, all of these are sustainable.
