Discover how to create a compact vertical-axis wind turbine with everyday materials in this detailed step-by-step guide. Watch as we build composite turbine blades, assemble a helical rotor, and ...

It's only fitting that the company generating electricity by loop-de-looping a ground-tethered winged drone is from North Carolina. After all, North Carolina is the birthplace of human flight. In 2023 ...

How can open ocean currents generate energy? Ocean currents contain kinetic energy that can be converted to electrical power using turbines. This is similar to offshore wind farms, or wind turbines ...

Dear Jim: I am tired of my high electric bills and consuming so much fossil fuels (coal, gas and oil). I like the idea of using a small windmill to produce my own electricity. What are the options for ...

Solar panels and wind turbines give the world bountiful energy — but come with a conundrum. When it’s sunny and windy out, in many places these renewables produce more electricity than is actually ...

Wind energy infrastructure doesn’t produce power if the air isn’t moving, and solar doesn’t generate power if the sun’s not out. But that doesn’t mean that either source of energy is "worthless" ...
