In the most ambitious US effort to stave off the worst of climate change, President Joe Biden has signed a number of executive orders to transform the nation's heavily fossil-fuel powered economy into a clean-burning one, pausing oil and gas leasing on federal land and targeting subsidies for those industries.

Biden acknowledged the political risk, repeatedly stating that his approach would create jobs in the renewable energy and automotive sectors to offset any losses in oil, coal or natural gas. "When I think of climate change and the answers to it, I think of jobs," Biden said. "We're going to put people to work. We're not going to lose jobs. These aren't pie-in-the-sky dreams. These are concrete actionable solutions. And we know how to do this."
In a change from previous administrations of both parties, Biden also is directing agencies to focus help and investment on the low-income and minority communities that live closest to polluting refineries and other hazards, and the oil- and coal-patch towns that face job losses as the US moves to sharply increase its reliance on wind, solar and other energy sources that do not emit climate-warming greenhouse gases.
Biden pledged to create up to a million jobs building electric cars, as well as installing solar panels, wind turbines, "capping abandoned walls, reclaiming mines, turning old brownfield sites into the new hubs of economic growth".
Even so, Republicans immediately criticised the plan as a job killer. "Pie-in-the-sky government mandates and directives that restrict our mining, oil, and gas industries adversely impact our energy security and independence," said Cathy McMorris Rodgers, the top Republican on the House Energy and Commerce Committee.
Biden also is elevating the warming climate to a national security priority, directing intelligence agencies, the military and others to do more to prepare for the heightened risks. The conservation plan would set aside millions of hectares for recreation, wildlife and climate efforts by 2030 as part of Biden's campaign pledge for a US$2 trillion programme to slow global warming.
President Donald Trump, who ridiculed the science of climate change, withdrew the US from the Paris global climate accord, opened more public lands to coal, gas and oil production and weakened regulation on fossil fuel emissions. Experts say these emissions are heating the Earth's climate dangerously and worsening floods, droughts and other natural disasters.
Currently, 61 per cent of the nation's electric power comes from natural gas and coal, 20 per cent from nuclear and 17 per cent from wind, solar and other renewable energy, the US Energy Information Administration says.

Georgia Tech climate scientist Kim Cobb said that "if this day seven momentum is representative of this administration's four-year term, there is every reason to believe that we might achieve carbon neutrality sooner than 2050," even as key roadblocks lie ahead.
Biden's actions came as his nominee for energy secretary, former Michigan Governor Jennifer Granholm, faced deep scepticism from Republicans as she tried to pitch the President's vision for a green economy.
"The last Democratic administration went on a regulatory rampage to slow or stop energy production," said Wyoming Senator John Barrasso, a leading Republican on the Senate Energy and Natural Resources Committee. "I'm not going to sit idly by ... if the Biden administration enforces policies that threaten Wyoming's economy."
Granholm, the leader of a state devastated by the 2008 recession, promoted emerging clean energy technologies, such as battery manufacturing, as an answer for jobs that will be lost as the US transitions away from fossil fuels. Granholm and other officials said the investment in cleaner energy national will net millions of jobs.
But that probably will take years to happen, and the orders will face intense opposition from oil and gas and power plant industries, as well as from many Republican — and possibly Democratic — lawmakers. "The environmental left is leading the agenda at the White House when it comes to energy and environment issues," said Kathleen Sgamma, president of the Western Energy Alliance, which represents oil and gas drillers in Western states. The group filed a legal challenge soon after Biden signed the orders.

Biden's directive to double energy production from offshore wind comes after the Trump administration slowed permit review of some giant offshore wind turbine projects. Significantly, he is directing agencies to eliminate spending that acts as subsidies for fossil fuel industries.
"The fossil fuel industry has inflicted tremendous damage on the planet. The administration's review, if done correctly, will show that filthy fracking and drilling must end for good, everywhere," said Kieran Suckling, executive director at the Centre for Biological Diversity, an environmental group that has pushed for the drilling pause.
The pause in onshore leasing is limited to federal lands and does not affect drilling on private lands, which is largely regulated by states. It also will not affect existing leases and could be further blunted by companies that stockpiled enough drilling permits in Trump's final months to allow them to keep pumping oil and gas for years.
The order exempts tribal lands, mainly in the West, that are used for energy production. Biden also will direct all US agencies to use science and evidence-based decision-making in federal rule-making and announce a US-hosted climate leaders summit on Earth Day, April 22.
