Technical potential

The theoretical maximum amount of emissions reduction that is possible from a particular technology (e.g. What would be achieved if every cavity wall were filled). This measure ignores constraints on delivery and barriers to firms and consumers that may prevent up take.

Tidal stream

A form of renewable electricity generation which harnesses the energy contained in fast-flowing tidal currents.


A type of forced induction system, which compresses the air flowing into a petrol or diesel combustion engine, squeezing more air into a cylinder, then allowing more fuel to be added. A turbocharged engine produces more power overall from each explosion in each cylinder, improving the power-to-weight ratio of the engine. One advantage is that it reduces fuel consumption without compromising engine performance.
