Every month it is the same sinking feeling. You open the electric bill, stare at the total, and wonder how a family that tries to be careful with power can owe that much. If you have done the usual things already, the LED bulbs, the thermostat nudges, unplugging chargers, and the bill barely moved, this Power Efficiency Guide review is for you.
The Power Efficiency Guide is a step-by-step DIY program by Mark Edwards that shows you how to build a small home power generator from inexpensive parts. It claims big cuts to your electricity bill and backup power for outages. Bold claims, so let us look at what it actually delivers, what it costs, and who it makes sense for.
Quick Verdict
Our rating: 4.2 out of 5
Best for: hands-on homeowners and renters tired of rising electricity costs who want a backup power source for emergencies.
Not for: anyone expecting a magic box that eliminates the bill entirely, or people unwilling to spend a weekend building something with basic tools.
Price: one-time payment of $49 (frequently discounted), with a 60-day money-back guarantee through ClickBank.
Bottom line: an honest, well-organized set of blueprints with realistic expectations. It will not power your whole house off the grid, but it is a legitimate weekend project that can trim your bill and give you backup power.
What Is the Power Efficiency Guide?
The Power Efficiency Guide is a downloadable program that teaches you to build your own small "mini power plant" at home. The idea comes from Mark Edwards, a teacher who started looking for an alternative power source after repeated outages and soaring bills at his own home. Working from research his late uncle left behind, he and an engineer friend built a working prototype from simple parts, then documented the entire build.
The guide itself is a digital ebook with illustrated blueprints, a materials list, and step-by-step instructions. You buy it once, download it instantly, and follow the plans at your own pace. Along with the main guide you get several bonus ebooks on saving power and cutting household costs, plus lifetime customer support if you get stuck during the build.
How the Power Efficiency Guide Works
The generator in the plans is built around what the guide calls the "endless power principle," the same self-charging concept used in electric vehicles, where the spinning wheels help recharge the battery while the car coasts. In this home version, a set of cogwheels, belts, and a rigid cylinder are arranged so the device keeps itself running, producing a steady supply of electricity you can route to your home appliances.
Now, a word of honesty. This is a small-scale generator, not a replacement for your utility connection. Think of it the way you would think of a backup generator, except silent, fuel-free, and cheap to run. Anyone promising zero bills forever is selling fantasy. What the plans realistically offer is supplemental power that shaves a meaningful chunk off your monthly total.
What You Get Inside the Power Efficiency Guide
- The main guide: complete blueprints with pictures, a shopping list of materials, and plain-language assembly instructions. The parts are said to cost around $106 at a typical hardware store.
- Five bonus ebooks: Saving Power, Saving the World, Money Saving Tips for Families, 15 Top Ways to Save Money, Go Green, Save Green at the Same Time, How to Be Environmentally Friendly.
- Instant access: everything is digital, so you can start reading minutes after checkout on your phone, tablet, or computer, even while standing in the hardware store aisle.
- Lifetime support: the creator offers ongoing help by email if a step in the build does not make sense.
- 60-day guarantee: the purchase is handled by ClickBank, which backs it with a 60-day, no-questions-asked refund policy.
Power Efficiency Guide Review: Pros and Cons
What we like
- One-time payment with no subscription and no shipping fees.
- Parts are cheap and available at ordinary hardware stores.
- Silent and fuel-free, unlike gas generators that annoy the neighbors.
- Useful as genuine backup power during outages and storms.
- 60-day refund window removes most of the risk.
- Beginner-friendly instructions with pictures, no engineering degree needed.
What to watch out for
- It requires a weekend of actual building. This is a DIY project, not a plug-and-play appliance.
- Savings claims of up to 60 percent are best-case numbers. Your results depend on your build and your usage.
- It supplements your power rather than replacing the grid. Large appliances like central air will still draw from the utility.
- Digital-only format. If you wanted a printed manual, you will have to print it yourself.
Who Should Try It, and Who Should Skip It
This program suits homeowners and renters who like hands-on projects and want two things at once: lower monthly bills and a quiet backup source when the grid goes down.
Skip it if you dislike building things, or if you are looking for a zero-effort fix. Nobody should buy this expecting to cancel their utility account. And if money is very tight, remember the build itself needs roughly a hundred dollars in parts on top of the guide, so budget for both.

Final Verdict
After a full Power Efficiency Guide review, here is where we land. This is not a miracle, but underneath the hype there is a real, coherent DIY project: clear blueprints, cheap parts, a silent fuel-free generator, and a genuine 60-day refund window that makes trying it low-risk.
