| Term | Definition | |
| OCEAN | The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Some believe that ocean power will provide a substantial amount of new renewable energy around the world. Difficulties arising from marine life attaching to energy systems in the seas require these to be easily cleanable. Renewable ocean energy The ocean presents a vast source of renewable energy in the form of winds, waves and tides. In addition, there is vast quantity of energy in the form of thermal difference which can be extracted. Several means of extracting energy from the ocean have been tried, some with limited success. 1. Wind power (offshore) 2. Wave power 3. Ocean thermal energy conversion (OTEC) 4. Tidal power Non-renewable ocean energy Oil and gas beneath the ocean floor are increasingly important sources of energy. An ocean engineer is concerned with all phases of discovering, producing, and delivering offshore petroleum resources, a complex and demanding task. Also of central importance is the development of new methods to protect marine wildlife and coastal regions against the undesirable side effects of offshore oil production. | |
| Oil | Oil, a liquid fossil fuel, is formed from layers of buried plants and animals that have been subjected to geologic heat and pressure over a long period of time. The energy that the plants and animals originally obtained from the sun is stored in the oil in the form of carbon. In addition to carbon, oil contains elements such as nitrogen, sulfur, mercury, lead, and arsenic. Oil is a nonrenewable resource because it cannot be replenished on a human time frame. | |
| OZONE | A kind of oxygen that has three atoms per molecule instead of the usual two. Ozone is a poisonous gas, but the ozone layer in the upper atmosphere shields life on earth from deadly ultraviolet radiation from space. The molecule contains three oxygen atoms (O3). | |
