Wind Energy News

Wind power is a source of energy that is both affordable and renewable. However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research was based on the assessment of the land-use of close to 320 wind farms in the U.S. paints a very different picture.

With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.

Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.

Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
