The US federal government has taken numerous actions to require cost / benefit analyses, or cost effectiveness analyses, regarding federal rulemaking activities. The intent of these actions is to assure that the rulemaking activities ...

In a summary of a recent peer-reviewed paper, the principal author stated that an electric grid predominantly powered by intermittent renewables such as wind and solar would require storage approximately equal to 25% of annual generation to...

Dominion Energy has proposed to build Coastal Virginia Offshore Wind (CVOW) a 176 wind turbine farm off the Virginia coast. The Virginia Legislature had predetermined that such a project was in the public interest. The Virginia State ...

The stated goal of the US Administration’s renewable energy transition is to replace all dispatchable fossil-fueled electricity generation and all direct fossil fuel usage with renewable electricity to reduce CO2 emissions. Logically,...

Developers of renewable energy generation installations frequently focus their marketing efforts on estimates of the number of homes the installations would serve. The developers’ estimates are not based on consistent assumptions and ...

Wind is intermittent. Therefore, wind generation is intermittent. Wind is unreliably available around the clock. Wind conditions vary geographically and seasonally. Therefore, wind generation potential varies geographically and seasonally. ...

The US currently consumes approximately 97 quadrillion British Thermal Units (BTU) of energy in all forms each year (97 Quads). Since this quantity of energy and the forms of energy which constitute it vary over time, this analysis will use...

Dominion Energy has proposed Coastal Virginia Offshore Wind (CVOW), the first large offshore wind project in the United States. CVOW would be a 2.6 GW wind farm consisting of 176 15 MW wind turbines, 3 offshore electric substations,...

The year, 2023, was not a good year for the offshore wind industry, which has seemingly been beset by adversity on all sides.

Supply chain disruptions, largely resulting from the COVID pandemic and national efforts to deal with the ...

"A goal without a plan is just a wish." – Antoine de Saint-Exupéry

The Biden Administration has yet to release a plan to reach its stated CO2 emission reduction goals for 2030, 2035 and 2050. However, the ...

The path to new technology consists of research, development, demonstration and finally deployment. Research and development frequently continue in an effort to improve the technology. However, at some point, the technology is determined to...

This commentary provides a simplified overview of the process of replacing a single dispatchable powerplant with either wind or solar generation plus storage.

The powerplant to be replaced is a 1,000 MW plant, either coal or nuclear fueled...

The US transition to renewable electric generation is proceeding down a path which assures that electric rates will rise. Wind and solar are “source of opportunity” generators, producing electricity when the wind blows and the ...

Preference :the act, fact, or principle of giving advantages to some over others
:priority in the right to demand and receive satisfaction of an obligation

The federal government, state governments and state utility regulators have ...

There has not been a successful demonstration of a renewable plus storage grid, even with generation support from fossil, nuclear, geothermal and biomass generators. Previous commentaries (here, here and here) have described a conceptual ...

The Administration goal of a fossil free grid by 2035 would require that the renewable portion of grid energy supply be supported by additional renewable generation plus electricity storage. The hourly, daily, monthly and seasonal ...

The capacity factor of wind generation systems varies as a function of geography, season of the year and time of day. The capacity of wind generation systems varies as a function of swept area, wind speed and turbine height. The current US ...
