How does solar energy work and how clean is it?
Solar power is an abundant renewable energy source and the technology to harness it keeps evolving. One of them is photovoltaic solar panels. No carbon emissions are associated with the generation of energy from solar panels once they are installed, but there are other factors to think about. From the material extraction for the cells to the disposal methods at the manufacturing plants, how clean really is solar?

Renewable energy capacity worldwide did not grow in 2018
It is the first time since 2001 that the renewables' power capacity did not increase compared to the previous year. On top of that, CO2 emissions from the power sector rose to a historic high, which has people worried.
