Solar PV rapidly becoming the cheapest option to generate electricity

Solar PV rapidly becoming the cheapest option to generate electricity

For a long time, the holy grail of solar photovoltaics (PV) has been "grid parity," the point at which it would be as cheap to generate one's own solar electricity as it is to buy electricity from the grid. And that is indeed an important market milestone, being achieved now in many places around the world. But recently it has become clear that PV is set to go beyond grid parity and become the cheapest way to generate electricity. Whenever I say this I encounter incredulity, even vehement opposition, from friends and foes of renewable energy alike. Apparently, knowledge of the rapid developments of the last few years has not been widely disseminated. But it's happening, right under our noses! It is essential to understand this so that we can leverage it to rapidly switch to a global energy system fully based on renewable energy. A hundred solar cells, good for 380 watts of...
