1) Alternative energies?
Energy sources that replace fossil fuels—typically renewable or low‑carbon (solar, wind, hydro, geothermal, biomass, tidal, etc.).
2) How tidal power works?
Rising/falling tides or tidal currents turn turbines (barrages, tidal-stream turbines, or lagoons); turbines drive generators that produce electricity.
3) Formula for energy efficiency?
η = (useful energy output / energy input) × 100% (or η = P_out / P_in × 100%).
4) How a hybrid car charges its battery?
Regenerative braking converts kinetic energy to electricity; the engine can drive a generator/alternator to charge; plug‑in hybrids can also charge from the grid.
