Solar Power 101 — Turning Light into DC and Connecting It to the Grid and Batteries

Solar power is a system that converts light into DC electricity at a photovoltaic cell's pn junction, then delivers it to loads or the grid via MPPT, an inverter, and a transformer. This piece organizes I-V characteristics, the effects of temperature, shading, and irradiance, grid interconnection, batteries, current equipment, and cutting-edge perovskite research, with equations and diagrams.

Wind Power Primer — Turning the Momentum of Wind Into Rotation, Electricity, and Grid Control

In wind power, blades capture the momentum of wind, spin, and a generator plus inverter convert that spin into electricity. This article works through the Betz limit, pitch/yaw control, fixed- vs. variable-speed systems, offshore wind, forecasting, grid interconnection, noise and bird strikes, and current floating-turbine research, with equations and diagrams.
