On Monday, President Donald Trump opened his second term with an inaugural address declaring that America has a “national energy emergency.” Vowing to tap into the country’s vast oil and gas reserves, Trump dismisses the overwhelming majority of climate scientists who say burning fossil fuels releases greenhouse gases that overheat the planet.

Economists and analysts aren’t convinced that an expansion of oil and gas production will lower consumer prices.

President Trump made energy a top priority on his first day in office, declaring a national emergency – which no president has ever done before. The implications aren't clear.
