In September, the United States was at its lowest coal stockpiles since 1978 – Today in Energy – U.S. Energy Information Administration (EIA)
Because of less coal consumption as well as coal capacity retirements over the past three years, the days of burn of U.S. coal remain within the typical range, even though total stocks are low. For bituminous coal plants, largely located in the eastern United States, the average number of days of burn was 88 days in September, a slight increase from the 86 days of burn recorded in August. The average number of days of burn for subbituminous units, most of which are in the western United States, was 82 days in September 2021.
Given the long-term trend of declining coal consumption, many U.S. mines have begun to close. Reduced production capacity and supply chain disruptions have created some concerns about the ability of coal-fired generators to replenish stockpiles to last through the winter (October–March).
Electric grid operators are closely monitoring coal inventories this winter. PJM, the grid operator for the largest electric system in the United States, instituted temporary changes to rules governing minimum inventory requirements to provide more flexibility for coal-fired generators, given low stockpiles at some plants and supply chain disruptions.
Warming planet slows jet stream causing downpours
Specifically, our reporting finds:
At some point over the past three years, 27 states – all east of the Rocky Mountains – hit their highest 30-year precipitation average since record keeping began in 1895. A dozen states, including Iowa, Ohio and Rhode Island, saw five of their 10 wettest years in history over the past two decades. Michigan saw six of its wettest 10 years on record over the past 13 years. In June, at least 136 daily rainfall records were set during storms across five states along the Mississippi River. At the opposite extreme, eight states – including five in the West – had at least three record-dry years in the same time period. That’s double what would be expected based on historical patterns.
The High Pressure Sodium Light: Ubiquitous, effective, but good?
Ever wonder why street lights are orange? For such a fast-paced world technology-wise, it seems somewhat odd that we are still using such a strange color of light for outdoor lighting. Well it turns out it is still a pretty good light source, though with limited use and perhaps a not-so-obvious flaw.

The report recommends hiking federal royalty rates for oil and gas drilling, which have not been raised for 100 years. The federal rate of 12.5% that developers must pay to drill on public lands is significantly lower than many states and private landowners charge for drilling leases on state or private lands.
The report also said the government should consider raising bond payments that energy companies must set aside for future cleanup before they drill new wells. Bond rates have not been increased in decades, the report said.
The Bureau of Land Management, an Interior Department agency, should focus leasing offers on areas that have moderate to high potential for oil and gas resources and are close to existing oil and gas infrastructure, the report said.
