Aussie/US group improves solar cell efficiency to capture 40% of solar energy
http://www.juancole.com/2014/12/record-scientists-efficiency.html
UNSW’s solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported.
The world-beating efficiency was achieved in outdoor tests in Sydney, before being independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in the United States.
The work was funded by the Australian Renewable Energy Agency (ARENA) and supported by the Australia–US Institute for Advanced Photovoltaics (AUSIAPV)
“This is the highest efficiency ever reported for sunlight conversion into electricity,” UNSW Scientia Professor and Director of the Australian Centre for Advanced Photovoltaics (ACAP) Professor Martin Green said.

We're getting to the point where we might really be able to get most or all of our energy needs from renewables. Combine this with the new household battery from the makers of TESLA and I wonder how close we are.
