Simple cycle gas turbine plants (dashed line) required similar prices to gas - fired thermal plants until 1985 - 90, when improving turbine efficiency reduced fuel and lowered required prices.

Not exact matches

By comparison, today's simple cycle power plants (gas turbine generator only) operate with efficiencies ranging between 33 and 44 percent depending on the size and model.

Some say thermometers are flawed and the world isn't warming much, others that warming and cool spells are the result of solar vagaries, ocean cycles or simple random variability in a sloshy system (basically anything but greenhouse gases, their critics note).

This simple illustration is only part of the carbon cycle, increased calcification will remove carbon dioxide from the water, allowing for the dissolution of more gas.

MAGICC is itself a collection of simple gas - cycle, climate, and ice - melt models to efficiently emulate the output of complex climate models.

The emission data were converted to concentration data, using a selected simple carbon - cycle climate model for well - mixed greenhouse gases and an atmospheric chemistry model for reactive short - lived substances.

The Kawasaki Heavy Industries (KHI) M7A is a single - shaft, simple - cycle, axial - flow, high - efficiency gas turbine engine in the 5.5 to 7.4 MW class.

Yet a simple calculation will show that less than 10 years of greenhouse gas forcing offset the difference between the peak and trough of the solar cycle, so this is not possible without widespread and sustained vulcanism — is he predicting this?

Worse, these would need to be inefficient simple - cycle gas turbines (due to the need to be able to ramp up and down within minutes if the wind changes) meaning that the CO2 emissions reductions compared to using gas alone (using more efficient combined - cycle gas turbines) are negligible.
