PHILADELPHIA (AP) -- The White House has released a four-year energy plan designed to fight climate change, modernize power plants and find other ways to ensure the nation a steady supply of safe energy.
Vice President Joe Biden plans to visit the Peco Energy Company in Philadelphia on Tuesday afternoon to discuss the administration's Quadrennial Energy Review.
The report notes that the U.S. has become the world's leading producer of oil and natural gas combined as its dependence on foreign oil declines.
The review finds that electricity from solar sources has increased 20-fold since 2008, while the amount of wind energy produced has tripled.
The report follows meetings with major utility firms and other stakeholders.
Officials say the challenges ahead include protecting energy plants from cyber and physical threats.
