But so is the cost of any method of reducing greenhouse gas emissions enough to make a similar difference — whether it's doubling the fuel efficiency of every single car and truck on the road (which would cost a few trillion dollars and take at least 15 years) or building scores of new wind turbines for each turbine already turning today or erecting hundreds of new solar cell arrays for every array in use today.

Designing wind farms with close packing of turbines, based on schooling fish, could greatly increase efficiency, say researchers at a meeting of the Division of Fluid Dynamics of the American Physical Society.

In wind turbines, carbon fiber's stiffness means rotors can use longer blades, thereby increasing the efficiency of each individual generator.

The techniques for achieving energy efficiency are many: daylighting strategies that determine the orientation of a building, and the size and placement of windows; automated controls that measure daylight levels and regulate the amount of artificial light needed; and alternative energy sources such as solar panels, wind turbines and geothermal wells.

The electric energy that wind turbines and solar panels produce will be converted into kinetic energy in an electric car with an efficiency of > 80 %.

Steady state energy must come from the sun, so I'd start with insolation and work from there, using the efficiency of photosynthesis, photovoltaics, wind turbines, etc..

It could be said that before windmills and wind turbines all the energy in the wind was being wasted — that is, the efficiency of converting wind energy to useful work was 0 %.

Mr Libby felt that this rate of «efficiency», 24 %, justified calling the wind turbine «absurdly inefficient», even though it is very similar to the efficiency of a coal - fired power station and far better than the 15 % efficiency we get from our cars if you calculate the energy available in the fuel and the power delivered to the wheels.

Dr Shahriar Hossain from the University of Woolongong in Australia is looking to overcome the problems posed by gearboxes in wind turbines by replacing them with a superconducting coil to slash production costs and drastically improve efficiency.

Libby calculates that at a wind speed of 14m / second a particular turbine will generate 2MW of electricity while the total power available in the air passing through the turbine is 8.5 MW (giving an efficiency of about 24 %, very similar to that of coal - fired power stations).

Frederic Hauge, director of the environmental group Bellona, says solar power and wind turbines and energy efficiency are all worthwhile, but they won't replace fossil fuels anytime soon.

Requiring no gigantic «smart grid» sucking the efficiency like a vampire — things that are inherent to these nasty wind machines — Nuclear SMRs are going to allow us to meet all our CO2 reduction goals, without the canard of «nominal power output» being accepted by the lost eco-sheep, and without the 100 % conventional, CO2 - generating backup generators — which must be kept on idle at all times should the wind die down, or a cloud pass over a solar cell — and which all of these wind turbines require.
