How can we store renewable energy? 4 technologies that can
3 · Mechanical energy storage harnesses motion or gravity to store electricity. If the sun isn''t shining or the wind isn''t blowing, how do we access power from renewable sources? The key is to store energy produced when renewable generation capacity is high, so we can use it later when we need it.

How a Wind Turbine Works
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

How do inverters convert DC electricity to AC?
O ne of the most significant battles of the 19th century was fought not over land or resources but to establish the type of electricity that powers our buildings.. At the very end of the 1800s, American electrical pioneer Thomas Edison (1847–1931) went out of his way to demonstrate that direct current (DC) was a better way to supply
How do electric kettles work?
An energy-efficient lamp rated at 10 watts uses 10 joules of energy every second (because 1 watt means using one joule per second), so it would take it 37,800 seconds—about 10.5 hours—to use as much energy as our kettle uses in a single boil!
