Russia's increased oil and gas revenue in 2021 is primarily the result of pandemic-related factors rather than President Biden's energy policies.
In 2020, global energy demand dropped due to business closures and restrictions on mobility enacted in response to COVID-19, driving down prices. Russia's oil and gas revenues subsequently took a hit.
In 2021, global energy demand recovered as lockdown measures were lifted and the economy reopened, driving up prices. Russia's oil and gas revenues rebounded in tandem.
President Biden's shutting down of the Keystone XL pipeline did not affect energy prices in the short-term as it was non-operational, being only 8% complete when construction was stopped. However, because it could have boosted supplies in coming years, its cancellation could theoretically impact price trends in the years to come.
