We at the Union of Concerned Scientists think a lot about windpower. In honor of Global Wind Day , here’s a roundup of what we’re seeing and what we’ve been thinking—five facts about wind energy to keep in mind as you celebrate, or at least make note, on June 15. Windpower is big, and getting bigger.
Windpower costs fell by half from 2008 to 2021. Rooftop solar costs in 2020 were a third of what they had been in 2010. In 2020, the cost of single-axis utility scale solar was only a fifth of what it was in 2010. Utility-scale solar was an even more dramatic story.
This is just one finding of a computational study on wind turbines’ effects on the airflow around them, and consequently the ability of nearby turbines – and even nearby wind farms – to extract energy from that airflow. Charles Meneveau of Johns Hopkins University in Maryland welcomes the research. “In
GW of wind capacity in September 2016, which produced 21 TWh in 2015. Windpower currently employs a little less than 15,000 people. The sector has 8,230 direct jobs (compared to a massive 32,000 in 2010-2011… or 12,000 in 2012). The target capacity for 2018 is of 15 GW. click to enlarge. click to enlarge.
I thoroughly enjoyed moderating a panel in the Nature Zone at COP27 with representatives from the International Renewable Energy Agency and Orsted, a leader in offshore windpower production based in Denmark, focusing on the potential of offshore wind energy and how to sustainably and equitably advance its development.
In 2010, China was producing 95% of rare earth elements , but since 2016 has decreased rare earth element mining down to 60% of world production today. In Baotou, Inner Mongolia, 1 in 7 Baotou residents—a city of several million—has cancer. A large rare earth element waste lake is located twenty minutes from the city center.
Today, oil producers are spreading disinformation about offshore wind in the worst way. They are sowing distrust and doubt and wasting precious time during which we should be accelerating windpower development.

Voters in Los Angeles County recognized the critical need to address climate change when they overwhelmingly rejected Proposition 23 — the 2010 ballot measure that would have suspended California’s landmark global warming law. In fact, many people, millions, are suffering already.”.
Similarly, a voluntary carbon offset market called the Chicago Climate Exchange collapsed in 2010 when prices fell, in some cases as low as five cents per ton, due to oversupply. Local Law 97 and these rules face the same risk now.
ERCOT also expected, during peak demand events in winter, to have power from wind represent about 27% of installed wind capacity. In its most severe appraisal of the loss of wind capacity, ERCOT expected 8% of windpower compared to capacity. link] [24] In re Erving Industries, Inc., 354 (Bankr.
Maine can capitalize on falling costs and federal incentives Like land-based wind and solar photovoltaics, the cost of offshore wind is projected to fall rapidly over time as the technology matures and the supply chain grows. NREL and DNV expect floating offshore wind costs to dip to $60 to $80/MWh by 2030 and $45 to $50/MWh by 2035.
In its papers supporting the order to show cause, the attorney general said that PwC had served as Exxon’s independent auditor since before 2010 (the time period covered by the subpoena), a role in which PwC examined whether Exxon’s financial statement disclosures were supported by evidence.
Around 2010, Vietnam stopped building big dams, instead favouring coal power, when it released its seventh power development plan (PDP7) for 2011–2020. Data from Global Energy Monitor show that since 2010 Vietnam’s coal sector has received at least US$29 billion in foreign investment. Investment drying up.
From the abrupt halt to support to photovoltaics in Spain in 2009 to issues with the territorial planning of incentivised windpower in France and Germany (or near Donald Trump’s golf course …) renewable energy policy can prove hard to manage, even (or especially?) when it relies on apparently simple market-based instruments.
52] And from 2010 to 2019, consumers from across the U.S. billion more than they would have had they purchased power from legacy utilities, according to a recent Wall Street Journal analysis. [53] Evaluation of a proposal for reliable low-cost grid power with 100 percent wind, water, and solar,” PNAS 114, no.
Deserts are also useful sources of windpower. There are always desert winds, but at certain times of the year wind is much higher which can also generate energy (34). In 2010, satellite data appeared to suggest a lower temperature than this was recorded but it was never confirmed or backed up by other data (39).
Then there is the Bureau of Ocean Energy Management (BOEM) and Bureau of Safety and Environmental Enforcement (BSEE), both created by splitting the Minerals Management Agency in the wake of the 2010 BP oil spill. Notably, the Biden Administration seeks to build 30 gigawatts of offshore windpower by 2030.
With respect to the analysis of climate change impacts, the appellate court said the City of Brea had appropriately selected a significance threshold for project greenhouse gas emissions that was higher than one used for a similar residential project in 2010.
Solar and windpower have enjoyed steep increases since 2010, and now produce more power than coal. Today, energy production exceeds energy consumption by approximately 10 percent. Petroleum consumption peaked roughly in 2005, then declined about 10 percent.
