Inflation dictates that the cost of living will continue to rise — except, it seems, when it comes to renewable energy. The cost of building a new utility-scale solar or wind farm has now dropped below the cost of operating an existing coal plant, according to an analysis by the investment bank Lazard. Accounting for government tax credits and other energy incentives would bring the cost even lower. "There are some scenarios, in some parts of the U.S., where it is cheaper to build and operate wind and solar than keep a coal plant running," said a Lazard banker who was involved in the report. "You have seen coal plants shutting down because of this." Every year, the investment bank analyzes the cost of different types of energy using a metric called the levelized cost of energy, or LCOE. This analysis factors in the cost of components and the cost of operations, as well as the cost of debt, to come up with the smallest dollar amount, per unit of energy, for an investor in the project to see a 12 percent return. The LCOE for coal this year is between $27 and $45 per megawatt. That figure is […]
