Infrastructure policy of the Joe Biden administration

In late January 2021, the Joe Biden administration stated it would aim for massive spending on the nation's infrastructure on the order of $2 trillion.
In April 2021, the administration rolled out an executive-branch proposed infrastructure blueprint—the American Jobs Plan—to expend some of federal funding on a wide variety of US infrastructure. The proposed blueprint is being discussed and debated presently and some major part of it is expected to make it into US law.
Background.
President Biden presented his Build Back Better plan on his first speech to a joint session of Congress. The plan calls for massive spending on the nation's infrastructure on the order of more than $2 trillion. The plan involves infrastructure, clean energy, manufacturing, research and development, and training. The plan borrows from many of the features of a "Clean Cars for America" initiative co-sponsored in October 2019 by Sen. Chuck Schumer.
Key Biden proposals include:
Energy.
Electrical power grid.
The electrical power grid would presumably receive some amount of the expected to by put forward by the administration for "electrification" as part of the Biden infrastructure plan being talked with Congress as of April 2021.
Keystone Pipeline.
In his first day in office, Biden had rescinded the permit for the Keystone XL oil pipeline with an executive order and rejoined the United States into the Paris Agreement abandoned in the Trump administration. Phase 4 of the Keystone XL pipeline had been a massively funded infrastructure project that was planned to run from Alberta, Canada to Nebraska and link to pipelines to Texas and Illinois oil refineries. The cancellation of the project had sparked northern objections from provincial premiers as well as Canadian Prime Minister Justin Trudeau, addressing his concerns in a call with Biden.
Renewable energy.
Renewable energy would presumably receive some amount of the expected to be put forward by the administration for "electrification" as part of the Biden infrastructure plan being talked with Congress as of April 2021.
Cybersecurity of critical infrastructure.
In 2020, a major cyberattack by a group backed by a foreign government penetrated thousands of organizations globally including multiple parts of the United States federal government, leading to a series of data breaches. The hacking group Cozy Bear (APT29), backed by the Russian intelligence agency SVR, was identified as the likely culprit. The cyberattack and data breach were reported to be among the worst cyber-espionage incidents ever suffered by the U.S., due to the sensitivity and high profile of the targets and the long duration (eight to nine months) in which the hackers had access. Within days of its discovery, at least 200 organizations around the world had been reported to be affected by the attack, and some of these may also have suffered data breaches. Affected organizations worldwide included NATO, the U.K. government, the European Parliament, Microsoft and others.
Transportation.
The vast majority of passenger travel occurs by automobile for shorter distances, and airplane (or railroad, in some regions) for longer distances. In descending order, most cargoes travel by railroad, truck, pipeline, or boat; air shipping is typically used only for perishables and premium express shipments. Transportation is the largest source of greenhouse gas emissions by the United States.
Impact.
Biden's infrastructure plans are predicted to create more jobs, strengthen short- and long-term economic growth, and increase lower- and middle-class incomes. Critical to this were Biden's proposals including expanded public education, elderly healthcare, and paid family leave, in contrast with Trump's restrictive immigration policies, which were projected to dilute workforce size and productivity. An economic analysis from Moody's Analytics in September 2020 found Biden's infrastructure policy would create 2.7 million additional jobs and increase average American income by $4,800 during his first term, should particular policies become law, far exceeding Trump's infrastructure proposals, which would create 11.2 million new jobs and "minimal real income gain."
