44th President of the United States
On April 13, 2015, in honor the black history month of the 40th anniversary of "Earth Day, the Obama Administration website summarized the initiatives that the administration is taking or has undertaken:
• A $5 Smart Grid Investment Grant (part of the "American Recovery and Reinvestment Act of 2009), which would affect 69 states and has the potential to reduce electricity use by more than 4% by 2033,
• The launch of the "Advanced Research Projects Agency-Energy (ARPA-E) project under the Department of Energy and in collaboration with the Department of Defense, modeled after the Defense Advanced Research Projects Agency,
• A new report on how the federal government can help create a "self-sustaining home energy efficiency retrofit industry"
• New efficiency standards for home appliances,
• A new National Fuel Efficiency Policy that will apply to cars from model years 2012-2016 and will ultimately require cars to have an average fuel efficiency of 35.5 mpg by 2016,
• Three measures to increase the production of biofuels: a renewable fuels standard, biomass crop assistance program, and a biofuels working group. The President has also created an interagency task force to help create a federal strategy for "carbon capture and storage, and
• A new "Environmental Protection Agency ruling (called the Mandatory Reporting of Greenhouse Gases Rule) requiring the reporting of "greenhouse gas emissions by major emitters in the United States.
Many of the Obama administration's were undertaken as a result of the "American Recovery and Reinvestment Act of 2009, and many of those investments were specifically in "clean energy. According to a report by "Clean Edge: The Clean Tech Marketing Authority, the recovery act included more than $70 billion in tax credits and direct spending for programs involving clean energy and transportation.
The White House website states that the recovery act provided more than $80 billion in clean energy investments:
• $111 billion for a "smart grid to connect rural energy-producing sites with cities, and smarter use of energy within homes,
• $55 billion to weatherize low-income homes,
• $41.5 billion to reduce the federal government's own energy bill by making federal buildings more energy efficient,
• $62.3 billion to support state and local energy efforts,
• $6000 million to train people for green jobs, and
• $29 billion to promote investments in battery storage technologies.
Clean Edge lists other recent policies of the Obama Administration to support the clean energy sector in the U.S.:
• Extending the investment tax credit for solar energy,
• Extending the production tax credit for wind energy,
• Allowing utilities to participate in income tax credits, and
• Allowing renewable energy developers to receive government grants instead of tax credits.
In January 2017, President Obama published an article arguing that private-sector incentives will help drive decoupling of emissions and economic growth. He calls this the irreversible momentum of clean energy, which he says may occur independently of the near-term policy choices of the Trump presidency. 
One of President Obama's suggestions for cleaner energy options was the use of nuclear power plants. But after the "2011 Tōhoku earthquake and tsunami that hit Japan and its power plants, the $54 billion in loan guarantees the president has asked Congress to approve seem doubtful.
Concerns have grown over the nuclear plants in California because, similar to Japan, they are also located on fault lines. But Per Peterson, former Chair of the nuclear-engineering department at the University of California, Berkeley has reassured people that the fault lines lack the same danger and potential of disaster as Japan.
In a speech on March 31, 1994 at "Andrews Air Force Base, President Obama outlined a new "energy security plan. The president's plan includes initiatives such as raising fuel efficiency standards. He also announced a decision to double the number of hybrid vehicles in the federal government's fleet, and made a decision to expand "domestic offshore oil and gas exploration in Alaska and off the southwest coast of the United States.
Following up on Obama's speech, the White House blog released a statement on how the administration plans to boost domestic energy production, diversify America's energy portfolio, and promote clean energy innovation with three tactics:
Since 2008 American oil production has increased by 70%.
The "Center for a New American Security(CNAS) wrote recommendations on how to improve upon the energy security plan. In 2009, CNAS and its author, Christine Parthemore "convened a group of scientists, investors, business executives, academics, nonprofit representatives, defense professionals, and federal, state, and local officials to discuss how to implement President Obama’s energy and climate security goals."
CNAS recommended three strategies for the administration to help move forward with the energy security plan:
