In addition to carbon fiber blades sometimes being installed due to lower weight and higher strength and durability compared to fiberglass-epoxy composites, there are wind turbines with a modular wooden structural support trunk, which is stronger, lighter, easier to recycle and transport, and more carbon-neutral than steel.

Some authors say that carbon neutrality strategies focus only on carbon dioxide, but net zero includes all greenhouse gases. [28] [29] However some publications, such as the national strategy of France, use the term "carbon neutral" to mean net reductions of all greenhouse gases. [3] The United States has pledged to achieve "net zero" emissions ...
Wind farms are estimated to last 30 years: [13] after that the carbon emissions from repowering would need to be taken into account. Solar panels from the 2010s may have a similar lifetime: however how long 2020s solar panels (such as perovskite) will last is not yet known. [14]
Our elected leaders consider the complete environmental impact of wind farms, least they impose a solution that makes the problem worse. Offshore wind turbines won't reduce carbon dioxide ...
It also promised that 5 million metric tons CO2 annually would be avoided with the wind farm. In response to these remarks, in May 2020 and February 2021, I asked SCE for specific technical ...
The plan includes more renewables like wind and solar, but also allows Duke to build more natural gas plants and delay closing some coal-fired plants. New NC carbon plan includes more wind and ...
Land-based (onshore) wind farms have a greater visual impact on the landscape than most other power stations per energy produced. [46] [47] Wind farms sited offshore have less visual impact and have higher capacity factors, although they are generally more expensive. [42] Offshore wind power currently has a share of about 10% of new ...
After NextEra proposed a wind farm in Greeley County, Nebraska two years ago, Robert Bernt, a dairy farm owner in the area, helped to mobilize community members against the idea. Bernt estimated ...
