For about fifteen years the cost of new solar and wind electricity fell almost every year. In 2025 it rose. BloombergNEF puts its global benchmark for utility solar up 6% and offshore wind up 12% over the year, and Lazard has the levelized cost of US solar up 18%. The...

The levelized cost of energy, or LCOE, is a single number: a power plant’s total lifetime cost divided by the total electricity it produces over its life, usually quoted in dollars per megawatt-hour. It is the most-cited figure in energy — and the most misused....

A wind farm burns no fuel, so almost everything it will ever cost is spent before it sends out a single kilowatt-hour — and most of that money is borrowed. This is why the cost of capital, not the turbine, sets the price of clean power. For a utility-scale solar...

A peaker plant is a power station built to sit idle. It earns its keep by running a few hours a year, on the evenings when demand spikes and everything cheaper is already maxed out — and that scarcity is exactly why it produces the most expensive electricity on the...
