has renewed his focus on climate change mitigation and energy security as he secured an historic second term of office as President of the United States.
Following a decisive victory against his Republican opponent Mitt Romney, Obama gave a rallying speech to crowds in Chicago that returned to his theme of hope for the future of the nation.
The topic of climate change was largely absent throughout the campaign, with neither candidate raising the issue during the presidential debates.
But Obama invoked the issue in his victory speech, receiving one of the biggest cheers of the night. "Despite all our differences, most of us share certain hopes for America's future," he said.
"We want our children to live in an America that isn't burdened by debt, that isn't weakened by inequality, that isn't threatened by the destructive power of a warming planet."
He added that he was "more determined and more inspired than ever" to tackle issues facing the future of the US, including "freeing ourselves from foreign oil".
Obama's re-election will pave the way for the delivery of his "all of the above" energy strategy
that aims to develop every available source of US energy, including oil, gas, clean coal, wind, solar, biofuels and nuclear, while also taking steps to protect the climate.
With so many of the American public now accepting climate change challenges
it seems odd that it was not pushed more during the pre election.
