Claim: Wind energy generates a significant amount of waste.
@BusinessInsider, a YouTube page, made a video last year, asserting that wind turbines generates so much waste and asked if it wasn’t wise that we stop using it as a means to generate power.
This post has since gathered 1,432,673 views; 50,000 likes; 4,235 comments; 3,120 shares.
NatureNews, Africa’s foremost newspaper on climate change, which is dedicated to providing accurate insights to stop the spread of fake news particularly among users of social media, subjected the claim to fact checking.
Findings: Using the Google search tool in conducting this research, NatureFact, the fact checking unit of NatureNews, accessed a few papers and studies.
A thorough fact-checking investigation has revealed that this claim is true.
@BusinessInsider stated that wind turbines generate 40 million tonnes of waste annually.
@DWPlanetA said that 90% of a wind turbine can be recycled except for the blades.
@InsiderScience stated methods to recycle wind turbine blades.
@TheImpossibleBuild acquiesced to this.
UndecidedWithMatt also agreed with this.
Wind energy, like any other industry, generates some waste, but the amount and impact are often exaggerated
Types of waste generated by wind energy:
1. Blade waste: Wind turbine blades are typically made of fiberglass or carbon fiber. When they reach the end of their life (usually after 20-25 years), they can be challenging to recycle. However, many companies are developing innovative recycling methods.
2. Electrical waste: Wind turbines contain electrical components like generators, transformers, and converters. These components can be recycled, but some may end up in landfills.
3. Foundation and concrete waste: Wind turbine foundations are typically made of concrete. When a turbine is decommissioned, the foundation may be left in place or removed, generating waste.
Mitigating waste in the wind energy industry:
1. Design for recyclability: Manufacturers are designing wind turbines with recyclability in mind, making it easier to reuse or recycle materials.
2. Blade recycling initiatives: Companies like Vestas, Siemens Gamesa, and GE Renewable Energy are developing blade recycling programs.
3. Closed-loop production: Some manufacturers aim to create closed-loop production systems, where old turbines are recycled to produce new ones.
4. Responsible decommissioning: The industry is developing best practices for decommissioning wind turbines, minimizing waste and environmental impact.
Comparing waste generation:
Wind energy generates significantly less waste compared to traditional fossil fuel-based power plants. According to the National Renewable Energy Laboratory (NREL), wind energy produces:
– 0.2-0.5% of the waste generated by coal-fired power plants
– 0.1-0.3% of the waste generated by natural gas-fired power plants
In conclusion, while wind energy does generate some waste, the industry is actively working to minimize its environmental impact. As technology continues to evolve, we can expect even more innovative solutions to emerge.
Verdict: True. Wind energy does create a significant amount of waste.
