The following column is the opinion and analysis of the writer:
In a recent Star op-ed, Arizona Corporation Commission chair Lea Marquez Peterson argued that the demands of citizens for more renewable energy are unrealistic and naive, that only by using a mix of coal, natural gas, nuclear and some renewables can we have electricity that is safe, reliable, and affordable.
People are also reading… Fossil fuels aren’t safe. Burning coal harms human health as it releases sulfur dioxide and nitrous oxide, which worsens smog, asthma, and other diseases. It adds planet-warming carbon dioxide to an already overburdened atmosphere, thereby increasing the severity of wildfires, hurricanes, drought, and soil degradation. Leaks from production and storage of natural gas send methane, a gas 80 times more planet-warming than carbon dioxide, into the atmosphere.
Are fossil fuels and nuclear the most affordable sources of energy? History tells us that they are not. Fossil fuel cost is volatile, as anyone who has purchased gasoline knows. It is subject to massive disruption as winds of political change blow across the planet. Natural gas prices have quadrupled in the last year. Nuclear power plants have a history of huge cost overruns. Deploying new ones would require years of permitting, review by citizen groups and constant changes to design.
Meanwhile, the sun continues to shine, and the wind continues to blow. Its supply chain has not been disrupted.
