Live divergence board for annual bill and footprint — so cheaper kWh never pretends to be cleaner kWh.
Educational end-use sketch. Bill ≠ footprint. Not a utility audit or official grid factor.

01
A household has one set of end-use loads — lights, plugs, cooling, water heat, space heat. Those loads produce two different stories: what you pay and what you emit. Grid intensity and volumetric rates do not move in lockstep. Cheaper kWh is not automatically cleaner kWh.
This page’s framing is Bill ≠ footprint. The panel still totals annual dollars and kilograms, then refuses to treat them as one ranking.
That is a different job from personal carbon footprint (Inventory ≠ lever across lifestyle categories) and energy efficiency (Portfolio ≠ priority for upgrade payback). Here we stay on the house meter before you rank measures.
Decision framing: “Did the bill and the carbon story agree?” — not only “How many kWh?”
02
The unique affordance is the divergence board: twin annual readouts for bill and footprint, each compared as a percent versus a US-average baseline on identical loads. Divergence is bill Δ% minus footprint Δ%. When that gap is large, Bill ≠ footprint is not a slogan — it is the product.
Flip region chips only (France, Australia, California, Texas) and watch the two percentages peel apart while end-use kWh and heat amounts stay fixed. That is not a method-gap tax board, not a habit-error rail, and not a cooling-curve scrubber.
03
Customer charges and other fixed monthly fees add dollars with zero kilograms in this sketch. The high-fixed-charge preset makes the bill climb while the footprint barely moves — another Bill ≠ footprint path that has nothing to do with the grid.
Override $/kWh when you know your volumetric rate. Leave it blank to use the region default educational rate.
04
Lights & plugs, cooling, electric water heat, and space heat (gas, oil, propane, or electric) build the meter. Dual thin rails show relative $ and kg per slice. When the cost leader and the carbon leader disagree — gas heat vs dirty-grid cooling, for example — the panel flags it. That is end-use Bill ≠ footprint, not a lifestyle inventory stack.
05
Electric kWh is the sum of lights, cooling, water heat, and electric space heat. Bill is electric × rate, plus fuel cost for non-electric heat, plus fixed × 12. Footprint is electric × regional grid factor plus fuel emission factors. US compare recomputes the same loads on US-average rate and grid (no rate override).
Factors are educational averages — not your utility’s residual mix or tariff book.
06
After you see Bill ≠ footprint, upgrade order belongs on energy efficiency; lifestyle inventory on carbon footprint; backup kWh on battery storage; generation payback on solar ROI.
07
Scenario A — Gas heat Midwest. Load the US gas preset. Bill and footprint both sit near the US baseline, so divergence is small. That is agreement — still useful as a control.
Bill ≠ footprint appears when you change only the region chip, not when you rewrite every kWh field.
Scenario B — All-electric France. Same style of electric heat loads on a nuclear-lean grid: footprint Δ% should fall hard while the bill may stay elevated versus US rates. Divergence pp is the teaching number.
Scenario C — Australia + AC. Cooling-heavy loads on a carbon-heavy grid: footprint can outrun the bill story. Cost leader and carbon leader may also disagree across slices.
Scenario D — High fixed charge. California-style rates plus a large monthly fixed fee: dollars rise with little carbon movement. Bill ≠ kWh×rate sits beside Bill ≠ footprint.

Share links snapshot region, rate, fixed charge, loads, and heat. Live typing never rewrites the address bar.

Stop here for Bill ≠ footprint literacy on the house meter. Hand off for measure order, lifestyle inventory, backup energy, EV road cost, or geothermal loops.

Annual dollars on the utility story and kilograms of CO₂e from the same end-use loads can move in different directions when you change grid intensity or rates. A cheaper region is not automatically a cleaner region. The divergence board shows bill % and footprint % versus a US-average baseline on identical loads.
No. It is an educational sketch of end-use loads, volumetric energy cost, fixed charges, and region grid factors. Real bills include tiers, demand charges, taxes, and weather. Use a utility portal or an auditor for decisions.
Because Bill ≠ kWh×rate. Fixed customer charges add dollars with zero kWh and zero CO₂ in this sketch. The high-fixed-charge preset makes that gap visible next to Bill ≠ footprint.
Personal carbon footprint owns Inventory ≠ lever across lifestyle categories (travel, diet, waste). This page owns the house meter: electricity end-uses plus space heat fuel, read as Bill ≠ footprint. Use footprint for the yearbook; use home energy for the utility story.
Energy efficiency owns Portfolio ≠ priority — which upgrade to fund first by payback. Home energy owns the baseline bill and carbon picture before you rank measures. Hand upgrade order next door after you see Bill ≠ footprint.
Gas heat can dominate dollars while a dirty-grid cooling block dominates kilograms — or the reverse on a clean grid. When those leaders disagree, Bill ≠ footprint is not only a region story; it is an end-use story.
No. Region chips use educational average intensities and default rates. Your utility’s residual mix and tariff will differ. Override the $/kWh field when you know your volumetric rate.
