A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces.

A thyristor-switched capacitor is a type of equipment used for compensating reactive power in electrical power systems.

Thyristor-controlled reactors can be used for limiting voltage rises on lightly loaded transmission lines.

A solid-state semiconductor device with four layers of alternating P- and N-type materials.

A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning[1] and its acoustic effect on the Earth's atmosphere, known as thunder.

A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.

The threshold limit value (TLV) of a chemical substance is believed to be a level to which a worker can be exposed day after day for a working lifetime without adverse effects.

In particle physics, the threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they collide.

Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution.

The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, it has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012.

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232Th, as the fertile material.

American inventor and businessman who established the first investor-owned electric utility in 1882, basing its infrastructure on DC power.

Third-generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells.

Algae can be produced in ponds or tanks on land, and out at sea.

Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the "smell of natural gas" is due to the smell of the thiol used as the odorant.

A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film of photovoltaic material on a substrate, such as glass, plastic or metal.

A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness.

A valve that is controlled automatically by the set temperature of the temperature sensor.

Usage of the reactionary nature of salts when thay are hydrated and dehydrated for heat transfer.

Salinity gradient power is a specific renewable energy alternative that creates renewable and sustainable power by using naturally occurring processes.
