    Physicist, formerly at NASA's Jet Propulsion Laboratory

    Following current trends to second order, >95% of humanity’s energy needs will be downstream of solar panels by 2042, just 19 years away, and alongside enormous expansion in direct use of electricity, fuel consumption will grow to more than $25T/year in equivalent dollars.
