Protection against lightning strikes is built into the electrical systems of all wind energy projects. All wind turbines have a lightning protection system that includes grounding of each tower. The grounding system installed as part of the foundation is also used for lightning protection. These lightning protection systems act to dissipate lightning strokes into the ground. Consequently, a person standing next to a turbine when a lightning strike occurred would be at some risk that a ground potential rise could result in a voltage between the ground and the tower or between two spots on the ground. Project operations workers are probably at highest risk. This risk should be counteracted by safety procedures instructing workers (or others) not to stand near turbines during lightning activity.
A wind project would not increase long-term lightning hazards for residents in the project vicinity. In addition, the electrical system of a wind turbine project is normally completely independent of the residential distribution system in the project vicinity. Therefore, any faults or surges on the project's electrical system due to lightning strike or other causes would not extend to the local distribution system that provides power to residences in the area.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
