Trump's pitch for making the Mexico border wall 'beautiful': add solar panels

The president's 'put a solar panel on it' policy to fund the wall may be expensive, impossible to build - and it's unclear what the energy would be used for

The president this week proposed a radical way to fund his proposed Mexican border wall: covering it in solar panels.

The same Donald Trump who has spent years criticizing renewable energy as uneconomical and who has pulled the US out of the Paris climate agreement has now floated the idea of adding solar panels to his proposed barrier along the the US-Mexico border.
