GridBasics
Energy, made simple
Plain English · Non-partisan · Sourced

Energy sounds complicated. It really isn't.
Here's how it all works — and what you can do about it.

GridBasics is the friendly starting point for understanding how power gets made, moved, and used. No jargon, no agenda — every number is sourced, every trade-off is spelled out. Then we hand you simple tools to go from "someone should figure this out" to "here's exactly what I'm doing this weekend."

Heads up · Federal ITC status

Section 25D — the 30% residential solar tax credit — expired Dec 31, 2025. Buying cash or loan in 2026 gets zero federal credit. Third-party-owned systems (lease/PPA) still qualify through 2027. State incentives still live.

Interactive Energy Value Chain

Click any stage. Every technology we cover lives somewhere on this chain.

Generation, conversion, storage, distribution, consumption. Five stages. Every home, every city, every grid operates inside this loop. Tap in and explore the full map — each node opens to the technologies that make it work.

World Scoreboard

The 50-state scorecard. No commentary. Just data.

Composite scores across renewable share, solar + wind per capita, net-metering policy, permitting difficulty, EV adoption, grid carbon, and more. Each state opens to a full profile with sources and trend lines.

The Cost of Waiting

The average US household spent $12,400 on electricity the last five years. A median rooftop would have saved $7,800.

Our "Cost of Resistance" calculator shows, state by state, what residents have already paid vs. the counterfactual where renewables were deployed faster.
