Generating capacity at the end of 2016 was 197 GWe, comprising 9.5 GWe nuclear, 3.9 GWe hydro (plus 9.3 GWe pumped storage), 45 GWe onshore wind, 4.1 GWe offshore wind, 41 GWe solar, 20.0 GWe lignite, 22.7 GWe hard coal, 7.4 GWe biomass and 24.2 GWe natural gas (Fraunhofer Institute data).
In 2015 wind and solar PV had capacity factors of 20% and 11% respectively, compared with 97% for nuclear (IEA figures).
Federal Acquisition Regulation (FAR) Part 42 identifies requirements for documenting contractor performance evaluations for systems, non-systems, architect-engineer, and construction acquisitions.
This makes it unsuitable for measuring gun violence between people of certain relationships.
In contrast, the FBI’s Supplementary Homicide Reports (SHR) include details on the perpetrator and weapon but are more likely to be missing records because the FBI relies on police departments to voluntarily submit their homicide data on an annual basis.
According to a study by the Department of Justice, between 19, federal, state, and local agencies conducted background checks on more than 180 million firearm applications and denied 2.82 million gun sales to prohibited purchasers. Though majority of the transactions and denials reported by FBI and BJS are associated with a firearm sale or transfer, a small number may be for concealed carry permits and other reasons not related to a sale or transfer.
To date, the background check system has blocked over 3 million firearm sales to prohibited purchasers. "Background Checks for Firearm Transfers, 2013-2014." Bureau of Justice Statistics. A case-control study of 11 cities found that in a domestic violence situation, the perpetrator’s access to a gun increased the odds of femicide by more than five times (adjust OR=5.44, 95% CI = 2.89, 10.22). Campbell, Daniel Webster, and Jane Koziol-Mc Lain, "Risk Factors for Femicide in Abusive Relationships: Results from a Multisite Case Control Study," American Journal of Public Health 93, no. Both the Centers for Disease Control and Prevention (CDC) and the FBI collect data on firearm homicides — the former from medical examiners and the latter from local law enforcement. The CDC’s National Vital Statistics System records a higher percentage of all firearm deaths but fails to capture details about their circumstances, including the relationship of the perpetrator to the victim.
