    This is the best summary I could come up with:


    Advances with solar technology mean that it will also make it economically viable for a portion of these freestanding single-family homes to abandon the electrical grid altogether in the coming decades.

    Rather than abandoning the grid altogether, however, the researchers said it would make more sense at a macroeconomic scale for households to remain connected and feed excess energy back to other users during times of overproduction.

    The research was detailed in a study, titled ‘Two million European single-family homes could abandon the grid by 2050’, published in the scientific journal Joule.

    Lead researcher Felix Creutzig said the falling costs could mean that the world’s entire energy consumption in 2050 could be “completely and cost-effectively covered by solar technology and other renewables”.

    “The recent progress of renewables means that fossil fuel-dominated projections are no longer realistic,” said Femke Nijsse from the University of Exeter.

    “Using three models that track positive feedbacks, we project that solar PV will dominate the global energy mix by the middle of this century.”
