Energy is messy. These explainers make it a little less ridiculous — for readers, professionals, and companies alike.
A power system can have more installed capacity than peak demand and still face electricity shortages. Resource adequacy asks the question that actually matters: will enough generation, storage, imports, and flexible demand be available when the system needs them most?
Primary energy is where we start counting energy before it is transformed, refined, converted, or delivered to consumers. Sounds simple—until wind, solar, nuclear, gasoline, and electricity enter the room.
A kilowatt-hour is always a kilowatt-hour. But its carbon footprint can change dramatically depending on where—and even when—it was produced. Carbon intensity is the number that reveals the difference.
Grid inertia is the split-second buffer that slows sudden changes in power-system frequency. For a century, huge spinning generators supplied it almost accidentally. Now solar, wind, batteries, and power electronics are forcing grids to learn how to replace something nobody used to think much about.
Power and energy sound almost interchangeable. They aren’t. Power tells you how fast energy is moving, while energy tells you how much moved in total. That tiny distinction explains everything from your kettle and electricity bill to MW, MWh, batteries, power plants, EV chargers, and the grid itself.
Diesel is more than truck fuel. It is an energy-dense petroleum fuel built for compression-ignition engines—and one of the hardest fuels to replace. Here’s how diesel works, how it is made, why heavy industry still loves it, and why its future is suddenly up for grabs.
Price risk is the possibility that changing market prices will hurt your revenue, costs, or profitability. In energy markets, where electricity, gas, oil, and carbon prices can move brutally fast, understanding price risk can mean the difference between a healthy margin and a financial headache. Here’s how it works, where it comes from, and how energy companies manage it.
Merit order ranks power plants from cheapest to most expensive based on marginal cost. Then comes the strange part: the last plant needed can set the wholesale electricity price for everyone. Here’s why cheap wind can coexist with expensive power, why gas matters so much, and how renewables are rewriting the market.
A feed-in tariff (FIT) pays renewable energy producers a guaranteed price for the electricity they generate. Simple idea, massive consequences. Here’s how FITs work, why governments created them, where the money comes from, and why energy markets are now moving beyond them.
Decarbonization means cutting carbon emissions across electricity, transport, buildings, industry, and the wider economy. But it is not simply “use more renewables.” It means rebuilding how we produce energy, move people, heat buildings, make steel, finance projects, and ultimately run modern civilization.
