World estimates of PV optimal tilt angles and ratios of sunlight incident upon tilted and tracked PV panels relative to horizontal panels – Stanford

“A critical parameter for installing fixed-tilt panels is the tilt angle, since PV panel output increases with increasing exposure to direct sunlight. Energy modelers also need to know the optimal tilt angle of a panel for calculating regional or global PV output in a given location or worldwide.”

Solar PV and wind are on track to replace all coal, oil and gas within two decades

‘Solar photovoltaic and wind power are rapidly getting cheaper and more abundant – so much so that they are on track to entirely supplant fossil fuels worldwide within two decades, with the time frame depending mostly on politics. The protestation from some politicians that we need to build new coal stations sounds rather quaint.’

Pompeo, Trump’s Pick for Secretary of State, Is a ‘Great Climate Skeptic’ | NYtimes.com

‘Mr. Pompeo has questioned the scientific consensus that human activity is changing the climate, and he has strongly opposed the Paris Agreement, a pact among nearly 200 nations to address climate change. He told Congress last year during his Senate confirmation hearing for the C.I.A. post that the notion of climate change as a top national security threat was “ignorant, dangerous and absolutely unbelievable.”’
