The United States has moved towards energy independence in recent years, mostly through a boom in oil production in places like west Texas. Diversity among energy sources has also played a major role in this process.

Electricity is an example of innovation and diversification of resources in energy in the U.S. In 2018, three major energy categories drove the country’s electric output.

Fossil Fuels

A combination of natural gas, coal and several other sources were responsible for 2,651 billion kWh of electricity in 2018, according to the U.S. Energy Information Administration (USEIA). Overall, this accounted for 63.5 percent of total electricity generation for the year.

Nuclear

Worldwide, nuclear energy is responsible for approximately 10 percent of electricity production but last year in the U.S. it accounted for almost double that figure. USEIA reports that 19.3 percent of the country’s electricity comes from nuclear power.

Renewable

A large emphasis has been put on renewable energy sources in recent years and that is reflected in its electricity output in 2018. Last year, 17.1 percent of American electricity was generated with renewable resources. This accounted for 713 billion kWh of electricity total. The three leading sources of renewable electricity in 2018 came from hydropower, wind and biomass.

There have never been more viable resources for electricity generation in the United States than there are today, and the 2018 data is an example of the balance among these sources. While fossil fuels still make up the majority of American electricity output, nuclear and renewable energy sources have proven to make an impact and should continue to do so.

GE Vernova is adding HVDC capacity as grids scramble to serve data centers

GE Vernova is adding HVDC capacity as grids scramble to serve data centers

GE Vernova is enhancing its high-voltage direct current (HVDC) capacity as part of efforts to meet increasing demand from data centers. The company is navigating challenges in project timelines caused by equipment lead times, which now dictate power-plant schedules.

  • 01GE Vernova is expanding its HVDC capacity to support increasing data center demands.
  • 02Project timelines for power plants are now dictated by equipment lead times rather than design.
  • 03GE Vernova's initiatives occur amidst growing urgency to upgrade transmission capabilities.

SMR power deals hinge on fuel supply, licensing and waste, not just megawatts

SMR power deals hinge on fuel supply, licensing and waste, not just megawatts

As TerraPower's Natrium and X-energy's reactors move toward deployment, HALEU fuel availability, NRC licensing pathways, and waste handling plans are becoming key diligence points for enterprise buyers evaluating SMR power deals. The article argues these fuel and waste assumptions, once treated as policy footnotes, now belong in RFP checklists.

  • 01HALEU fuel supply has already delayed TerraPower's Natrium startup target from 2028 to 2030.
  • 02The NRC's Part 53 framework and the 2024 ADVANCE Act aim to streamline licensing for advanced reactors.
  • 03The article recommends buyers press vendors on fuel supply schedules, licensing pathway, and waste handling plans before signing.

Zinc and sodium-ion batteries emerge as alternatives to lithium's dominance

Zinc and sodium-ion batteries emerge as alternatives to lithium's dominance

Sodium-ion and zinc batteries are gaining traction in energy projects where cost constraints and specific environmental conditions, such as cold weather and fire safety, are critical considerations. These battery types offer alternative solutions for grid implementations that require reliability under challenging conditions. Their adoption highlights an evolving energy storage landscape focused on balancing performance, safety, and affordability.

  • 01A utility-owned 1-MW/6-MWh zinc battery system is headed to the University of Minnesota Morris, with Otter Tail Power owning and operating it and commissioning expected in 2027.
  • 02Sodium-ion batteries can reportedly operate from -40°F to 140°F without output degradation, potentially eliminating the need for HVAC systems in some deployments, unlike lithium batteries that need chillers and fans.
  • 03LFP still represented 80% of new battery storage worldwide in 2023, but ESS Inc. plans to release its first grid-scale sodium-ion product next year to compete in lithium's typical two- to eight-hour applications.
