The use of drones has expanded to a large extent. Drones present a series of opportunities for companies to save money on labour, enabling frequent checks, hence resulting in more accurate reporting. Beyond this, they can provide a positive impact to the energy sector. 

Mentioned below are some uses of drones in the renewable wind energy sector

Surveying and Mapping
When evaluating wind farms, it is essential to calculate possible interference. Drones can move throughout these regions collecting data on wind currents, sun exposure, and the ecosystem. This system is integrated into the agricultural industry with light detection and ranging sensors (LIDAR) attached to drones. In the case of inspections on energy infrastructure such as substations, drones can complete inspections in a fraction of the time with no shut-down required at all.
 
Issue Detection
The intervention of drones has greatly benefited the energy sector, as they can reach heights of even 400 feet, which helps evaluating issues safely and effectively. Drones use their imaging abilities to survey and map the land and detect renewable energy system issues. These detection methods are less expensive for renewable energy companies and enable workers to plan more efficient repairs.
When there are natural disasters, utility companies can deploy drones to quickly and easily navigate past fallen trees or flooding to collect information and restore power.
 
Renewable Energy Drone Production
Wind power-converting drones act as a sustainable alternative to wind turbines. Drones fly in circulation patterns which maximises the efficiency of wind capturing.
The developments in the drone industry now allows drones to fuel themselves using wind power.The Saildrone is a device that harnesses its energy from small propellers(similar to the head of a wind turbine). The energy reaches the Earth’s surface through an extended power cable, which is environmentally less disruptive than a turbine. The materials utilised in building a wind energy drone are less disruptive to the planet and require less greenhouse gas emissions in production. Without drones, wind turbine inspections would have to be done manually, which is a quite dangerous job. Inspections carried out using ground-based techniques alone would provide lower quality data and at the same time, would be time-consuming.
 
Solar Delivery Drones
Carbon emissions would be significantly reduced, with the incorporation of drones into the delivery industry, hence preserving the atmosphere. With renewable energy-powered delivery drones, truck-induced air pollution, traffic congestion, and roadkill could decrease to a great extent. Limiting these environmental harms can conserve the environment and increase biodiversity on Earth.
 
Drone Regulation
Restrictions on flying heights, speed, weight, certifications, site navigation, and more limit one’s ability to use drones for sustainability purposes. The strict aircraft regulations is the reason why we are still waiting for our drone-delivery amazon purchases. Innovators are working to develop green drone uses, but it will take time before they reach the commercial market. With the development of green drones, the renewable energy sector will grow at a rapid pace.
