Regarding “Georgia Power launches new solar partnership with corporations” (AJC.com, April 12), perhaps the author should back up the notion that renewable energy is “cost effective.” Is Google, situated in Atlanta, going to pay less per kilowatt-hour for solar electricity produced in Camilla rather than fossil-fuel electricity produced in Cartersville? Solar energy cannot be produced at night, nor is there a cost-effective, utility-grade storage medium to store solar energy for night-time use. Is Google going to shut down 66 percent of the day, or during a week of cloudy weather? I am all for renewables; they are great to shave peak demand, but awful for base power requirements due to their intrinsic unreliability. Does the author understand these terms and the profound implications? Going 100 percent renewable is a dream as bright as the sun but in practice as dark as a long winter’s night.

Trump’s super-thin skin on full display recently

The new book by former FBI Director James Comey has obviously gotten under the super-thin skin of President Trump. Never one to keep his thoughts safely tucked away in his stable genius brain, the president has lashed out at Comey as a “leaker and liar” and an “untruthful slime ball.” Apparently, Trump took exception to Comey’s characterization of him as “a relentless liar who is obsessively unethical, devoid of humanity and a slave to his ego.” Who should we believe? Assume you are a contestant on a TV show called, “Who Do You Trust?” You are shown videos of President Trump and James Comey each making a statement about any given topic. You are also told that one statement is true and one is false. When the emcee asks, “For $100,000 and a new Mercedes, who do you trust?” Would you trust Trump?
