Electric power can be sourced from a diversified grid and thus reduce the effects of oil and geopolitics. Petroleum and petroleum-based products were used as a weapon after the Yom Kippur War, quadrupling the price of oil after an OPEC embargo. In 2000, the fuel protests in the United Kingdom virtually crippled UK transport and left transport agencies only a day away from bringing the diesel railway to a standstill. The rate of electrification in Britain is often compared to overseas and many acknowledge it is a geopolitical and resource issue as petroleum is a finite resource. In addition, the 2022 Russian invasion of Ukraine highlighted issues with regards to countries being dependent on hydrocarbons from other countries with embargo risks.
