Alex is the content creator and energy researcher behind Green RoiLab's library of calculators and guides. Alex writes about renewable energy systems, electric vehicles, and home energy efficiency, turning complex data into clear, actionable information for homeowners.
Every calculator and article on Green RoiLab is built using publicly available data from authoritative sources — the U.S. Energy Information Administration (EIA), Department of Energy (DOE), National Renewable Energy Laboratory (NREL), Environmental Protection Agency (EPA), and the Internal Revenue Service (IRS). Alex researches, verifies, and presents this data so that anyone can understand their energy options without needing a technical background.
What drives Alex's work is a commitment to transparency and accuracy. Every claim in our content is linked to its original source. Every calculator is built using published, industry-standard formulas. There are no black-box algorithms — just honest math with real-world data.
Trust is earned through transparency. Every number on Green RoiLab comes from a verifiable source. When we say the average U.S. household spends $1,500 a year on electricity, we link to the EIA's latest data. When we calculate solar payback periods, we use the same methodology as NREL's PVWatts. Our content doesn't rely on opinions — it relies on data that you can check yourself. Learn more about how we research and verify every claim.
