Energy Guides
Learn how electricity pricing works and what drives regional differences. These guides break down Department of Energy EIA data on residential rates across all 51 states, explain how generation mix, regulation, and geography shape what you pay per kilowatt-hour, and cover the major energy sources powering the US grid.
Understanding Electricity Rates
What cents per kilowatt-hour means, how your bill is calculated, and what the EIA data shows about pricing across the US.
Why Energy Prices Vary by State
The factors that make electricity cheap in some states and expensive in others, from generation mix to regulation to geography.
US Energy Sources Explained
Natural gas, coal, nuclear, wind, solar, and hydro, how each source contributes to the grid and what it means for prices.
Cheapest States for Electricity
Which states have the lowest electricity rates, why hydropower and natural gas dominate the cheap end, and what it means for your energy costs.
Renewable vs Fossil Fuel Costs
How the cost of wind, solar, natural gas, and coal generation compare, levelized cost of energy and what it means for future electricity prices.
Understanding Electricity Rate Structures
Flat rates, tiered blocks, time-of-use schedules, and demand charges, how utilities price electricity and which structure your utility likely uses.
Comparing Utility Costs Across States
Why electricity prices vary by 4x across states, what drives the gap, and how to use rate data for relocation and business decisions.
Methodology
Our guides are based on publicly available data from authoritative government sources. All statistics, ratings, and figures cited in these guides are drawn directly from official datasets and publications, with sources clearly referenced throughout.
We aim to present complex government data in plain language that is accessible to general audiences. When methodologies differ between data sources or change over time, we note these variations inline. Our editorial process includes regular reviews to ensure accuracy and timeliness of the information presented.
This page is a navigation index; the guides it links to cite their own data sources inline. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of 2026-05-15.
