Pipeline sending natural gas from western Canada to Chicago considers expanding capacity
Owners of the Alliance pipeline, one of the longest natural gas pipelines in North America, are in the early stages of assessing interest in expanding its capacity to transport natural gas from western Canada to Chicago, Illinois.
Most U.S. nuclear power plants were built between 1970 and 1990
As of 2016, the United States had 99 operating nuclear reactors at 61 plants across the country, with a capacity-weighted average age of 37 years. The oldest operating nuclear reactor in the United States was built in 1969. Watts Bar 2, which entered commercial service in 2016, was the first new reactor added since 1996. An additional four reactors are currently under construction.
Permian Basin oil production and resource assessments continue to increase
Crude oil production in the Permian Basin is expected to increase to an estimated 2.4 million barrels per day (b/d) in May, based on estimates from EIAï¿½s Drilling Productivity Report. Between January 2016 and March 2017, oil production in the Permian Basin has increased in all but three months, even as domestic crude oil prices fell.
Ohio and Pennsylvania increased natural gas production more than other states in 2016
After reaching a record high of 79 billion cubic feet per day (Bcf/d) in 2015, U.S. marketed natural gas production fell to 77 Bcf/d in 2016, the first annual decline since 2005. Texas, the state with the most natural gas production, fell by 2.5 Bcf/d, while Ohio and Pennsylvania each increased by about 1.2 Bcf/d.
More than half of utility-scale solar photovoltaic systems track the sun through the day
The electricity generated by a solar photovoltaic (PV) system depends on the orientation and tilt of the PV panels, and in some cases, its ability to track the sun throughout the day. Because photovoltaic panels operate more efficiently when oriented directly at the sun, some systems use solar-tracking technology to increase electricity generation by rotating the panels along one or two axes.
