Photovoltaic technology directly converts sunlight into electricity. Solar thermal technology harnesses its heat. These different technologies both tap the Sun’s energy, locally and in large-scale solar farms.

Alongside wind, photovoltaic solar power is the fastest developing energy source worldwide. But it’s going to need to pick up speed to achieve the “carbon neutrality” objective by 2050, which means no more CO₂ emissions than the planet can absorb. To get there, more gigantic photovoltaic farms need to be installed and more building-integrated systems added to parking lot canopies, public buildings and people’s homes.
