Why Bad Climate Legislation Is Worse Than No Climate Legislation - by Michael Shellenberger - Michael Shellenberger

The “Clean Energy Performance Program” is not needed to meet climate goals, and might actually undermine them.

Consider Waxman-Markey. That’s the name of the “cap and trade” climate legislation that passed the House but failed in the Senate in 2010. It had a climate goal of reducing U.S. greenhouse gas emissions by 17 percent below 2005 levels by the year 2020. Instead, the U.S. reduced its emissions by 22 percent.

Had cap and trade legislation passed in the Senate, emissions would have declined less than 22 percent, because Waxman-Markey so heavily subsidized coal and other fossil fuels. As the Los Angeles Times reported at the time, “the Environmental Protection Agency projects that even if the emissions limits go into effect, the U.S. would use more carbon-dioxide-heavy coal in 2020 than it did in 2005.”

The same thing would likely have been true for the Clean Energy Performance Program, which lock in natural gas. Consider France. According to the Commision de Regulation de L’Energie, €29 billion (US$33) billion was used to purchase wind and solar electricity in mainland France between 2009 and 2018. But the money spent on renewables did not lead to cleaner electricity. In fact, the carbon-intensity of French electricity increased.

After years of subsidies for solar and wind, France’s 2017 emissions of 68g/CO2 per kWh was higher than any year between 2012 and 2016. The reason? Record-breaking wind and solar production did not make up for falling nuclear energy output and higher natural gas consumption. And now, the high cost of renewable electricity is showing up in French household electricity bills. //

What threatens the continued operation of nuclear power plants, and nuclear energy in general, is the continued subsidization of renewables, which the Clean Energy Performance Program would have put on steroids. Under the program, utilities would have received $18 for each megawatt-hour of zero-emissions energy it produces between 2023 to 2030, on top of the existing $25 per megawatt-hour subsidy for wind energy.

Under such a scenario, notes energy analyst Robert Bryce, a wind energy company "could earn $43 per megawatt-hour per year for each new megawatt-hour of wind energy it sells. That’s a staggering sum given that the wholesale price of electricity in New York last year was $33 per megawatt-hour. In Texas, the wholesale price of juice was $22 per MWh.” //

A better approach would be for Congress to seek nuclear-focused legislation to expand nuclear from its current 19% of U.S. electricity to 50% by 2050. It should take as a model the British government’s announcement yesterday that it would put nuclear energy at the center of its climate plans. Global energy shortages triggered by the lack of wind in Europe have led nations to realize that any efforts to decarbonize electricity grids without creating blackouts must center nuclear power, not weather-dependent solar and wind.

RPN -- Reverse Polish Notation

In the 1920's, Jan Lukasiewicz developed a formal logic system which allowed mathematical expressions to be specified without parentheses by placing the operators before (prefix notation) or after (postfix notation) the operands. For example, the (infix notation) expression

(4 + 5) × 6
could be expressed in prefix notation as

× 6 + 4 5 or × + 4 5 6
and could be expressed in postfix notation as

4 5 + 6 × or 6 4 5 + ×
Prefix notation also came to be known as Polish Notation in honor of Lukasiewicz. HP adjusted the postfix notation for a calculator keyboard, added a stack to hold the operands and functions to reorder the stack. HP dubbed the result Reverse Polish Notation (RPN) also in honor of Lukasiewicz.

In the years that followed, computer scientists realized that RPN or postfix notation was very efficient for computer math. As a postfix expression is scanned from left to right, operands are simply placed into a last-in, first-out (LIFO) stack and operators may be immediately applied to the operands at the bottom of the stack.
