Solar energy captures sunlight and turns it into power—clean, renewable, and abundant. The sun lights the way to a low-carbon future. ☀️⚡🌍

What is a Power Purchase Agreement (PPA)? The strange little contract behind big energy projects

Illustration of a Power Purchase Agreement (PPA) connecting solar and wind energy projects with an electricity buyer through a glowing contract bridge.

A power purchase agreement, or PPA, is one of the most important contracts in modern energy — and one of the least understood. It is how solar farms get financed, how companies lock in electricity prices, and how power gets sold before it is even generated. Here is what a PPA is, how it works, and why it matters more than most people realize.

What is curtailment? Why energy sometimes go to waste

Curtailment concept image showing a table full of food and drinks after a party, symbolizing available energy supply that cannot be fully used or absorbed by the system.

Curtailment may sound harmless, but in the energy world it’s a serious headache. When the grid can’t absorb all the electricity being generated, especially from wind and solar, operators are forced to reduce output. Here’s what curtailment means, why it happens, what it costs, and how smarter grids could reduce it.

What is LCOE: The true cost of electricity

LCOE (Levelized Cost of Electricity) is the go-to metric for comparing the true cost of energy—from solar and wind to nuclear and gas. It shows how much it really costs to generate power over a plant’s life. Simple, powerful, and essential for smart energy decisions. Here's what it means—and why it matters.

What is sustainability? Living on a borrowed Earth
