Geothermal Cooling: How Ground-Source AC Works
Geothermal cooling works like a conventional air conditioner, but it sends indoor heat into the ground instead of hot outdoor air. Because shallow ground temperatures are steadier than summer air temperatures, a ground-source … Read more
Geothermal Energy Pros and Cons: A Practical Guide
Geothermal energy can mean two very different technologies: deep geothermal resources used for electricity or direct heat, and shallow ground-source heat pumps used to heat and cool buildings. Both use the earth, but … Read more
Geothermal Tons per Square Foot: How to Size a System
There is no dependable geothermal tons-per-square-foot number. A rough estimate may put many homes near one ton per 400 to 600 square feet, but insulation, windows, air leakage, climate and occupancy can move … Read more
How Deep Are Geothermal Loops? Depth by System Type
Most residential geothermal heat-pump loops are either buried in trenches at least four feet deep or installed in vertical boreholes that extend hundreds of feet. The correct depth depends on loop type, frost … Read more
How Is Biomass Calculated? Mass, Energy and Carbon
Biomass is calculated differently depending on whether you need wet weight, dry matter, energy content or stored carbon. Mixing those measures creates major errors because water adds mass but little usable energy, while … Read more
Hydropower for Home: Is Microhydro Right for Your Property?
Home hydropower can produce steady electricity day and night, but only a property with enough year-round water flow and vertical drop is a serious candidate. Measure the site and check water rights and … Read more
