NSW One Nation leader Mark Latham says there is an “environmental downside” to solar and wind farms.

“Both solar and wind farms eat up vast tracts of land, the wind farms have an environmental cost in destroying prime agricultural land, and destroying millions of birds around the world,” Mr Latham told Sky News host Andrew Bolt.

“The solar also has the problem – it goes into landfill, its materials leak into waterways, there’s a problem with battery storage.

“And this is rarely mentioned in the debate.”
