| B. | Fossil fuel |
| C. | Nuclear power |
| D. | Wind energy |
| Answer» D. Wind energy | |
|
Explanation: Solar, wind and hydro power are examples of cleanest energy sources. According to a new US study, Greenhouse gases produced over the lifetime of a wind turbine are less than that of fossil-fuel based energy sources and most other renewable. Only ocean energy (wave and tidal) and hydropower have lower emissions than wind. As a clean, fuel-free source of energy, wind turbines create energy without generating the damaging pollutants. |
