A product catalog is a series of editorial decisions. We try to make ours transparent: this article walks through how we decide what goes on ShopForTerra, what we won't list, and how the rating system fits alongside those decisions.
The category scope
ShopForTerra focuses on home energy and efficiency products: solar panels, home batteries, portable power stations, insulation, and climate control. We chose this scope for three reasons:
- The category matters. Home energy use is a major slice of a typical household's environmental footprint and monthly spending. Small upgrades tend to compound — a more efficient air conditioner plus better insulation plus a small solar setup saves more than any one of them alone.
- The products pair with our tools. The calculators on this site are only useful if we can connect them to real purchaseable products. Sticking to a narrow category means the calculator results always land somewhere real.
- The research is sustainable. We can write a credible buying guide for portable power stations without pretending to be experts on every category online. Wide catalogs reward scale; narrow catalogs reward depth.
We don't list apparel, beauty, or general lifestyle products anymore — even attractively eco-branded ones — because we'd be spreading thin rather than going deep.
How a product gets listed
Most products start with reader interest (someone asks about a brand or category) or with a manufacturer or affiliate network approach. From there, the basic checklist is:
- A clear use case: a real reason a household trying to reduce energy use would consider this product.
- Real specs: published capacity, efficiency, warranty, or R-value figures that we can verify against the manufacturer's own materials.
- A reputable seller: an established affiliate merchant that can actually ship, support returns, and stand behind the warranty.
- Available in the markets we cover: currently the US and the UK, with US dollars or pounds sterling pricing.
If a product passes the checklist, we ask how it compares to the direct alternatives, not in isolation. A slightly better window AC only earns its place if it's a real competitor to the units around it.
The eco-score
Every product we list carries an eco-score from 1 to 10 and one or more eco-tags. The score reflects four factors:
- Energy savings (the largest weight — does the product genuinely reduce household energy use?)
- Durability (how long is it likely to last vs. the alternative?)
- Material impact (recycled content, repairability, end-of-life disposition)
- Brand behavior (warranty terms, repair availability, take-back programs)
The eco-tags are the supporting evidence — phrases like 'Plug-and-Play Solar,' 'Energy Efficiency,' 'LiFePO4,' or 'DIY Friendly' that show why the score is what it is. The full scoring rubric is published in our ratings methodology.
What we don't list
We won't list products that:
- Make unverifiable claims ('saves 99 percent on your energy bill!') without backing documentation
- Have no real warranty or return path
- Are sold primarily through un-refundable marketplaces
- Are obviously greenwashed — a low-impact product in an eco-friendly wrapper
The list evolves. As we develop merchant partnerships in additional categories, the catalog grows; as products are discontinued or fail to live up to claims, they're archived.
How recommendations land on the page
Featured products are the ones we believe are the strongest fit for a typical first-time buyer in their category — usually a balance of quality and price rather than the absolute cheapest or newest. The 'All Products' grid shows the full catalog, sorted by recency. Filtering by category narrows to that scope; the calculators surface a single recommended product given the parameters you enter, and that recommendation comes from the same pool.
If a product we've featured turns out to underperform expectations — yours or ours — we'd rather know, and we won't hesitate to take it down. The point is to make a recommendation you can use, not to keep the catalog padded.
