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 ...

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 ...

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,...
