A great example is a biofuel. This refers to any fuel produced from plants, algae, or animal waste, making it an eco-friendly and readily available source of renewable energy. These biofuels also produce fewer air pollutants such as carbon monoxide, air toxics, and sulphur dioxide, among others.

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. Cars and trucks are a lot cleaner than when I was growing up.

Between 1980 and 2018, US carbon monoxide levels decreased by 83 percent, lead by 99 percent, nitrogen dioxide by 61 percent, ozone by 31 percent, and sulfur dioxide by 91 percent. Subsidies and mandates for renewables result in higher electricity prices and the net transfer of wealth from lower to upper income citizens.
