Sentences with phrase «means more turbines»

Natural gas the real replacement, but new Michigan wind mandate means more turbine towers coming, too

Not exact matches

RW: With the current interest in buying electric cars, plus more wind turbines being built and growing Chinese infrastructure, does this mean the fundamentals are falling into place for rising copper prices and copper company share values?

A combination of structural and economic considerations drives the use of three slender blades on most wind turbines — using one or two blades means more complex structural dynamics, and more blades means greater expense for the blades and the blade attachments to the turbine.

Attaching turbines directly to the craft would mean more generators and therefore more power.

This means the turbine will not always have more than the pump will.

BMW's patented cross-bank exhaust manifolds are mounted inside the valley (V), making this engine a «Hot V.» The shorter pipe length means more efficient airflow on the way to the turbochargers, while a combustion chamber arrangement mirroring the firing sequence ensures a consistent level of pressure acting on the two turbochargers, without any kind of counterflow, for rapid turbine response and constant pressure charge.

One reason is that the game, while very much entertainment, forces players (at least the demo I saw) to make choices, to understand that forswearing coal means installing an amazing number of much more expensive wind turbines and solar panels.

If the lifetime of a wind turbine is 15 years rather than 25, that presumably means that the electricity it generates is going to be much, much more expensive.

This means that up to ten times more solar panels and wind turbines need to be manufactured.

Using data without a safety margin, such as mean values for a given turbine model, measurements from a single turbine, or «best guess» for future turbines gives in principle a probability of 50 per cent that the actual erected turbines will emit more noise than assumed and that noise limits will be exceeded.»

The fuel cell operates much more efficiently than a conventional gas - burning turbine, meaning it emits between 3,400 and 5,000 tonnes less CO2 per year.

To replace a 1500 MW coal plant with wind turbines means you will need way more than 1500 MW of installed capacity of wind generation to get an average of 1500 MW of power even if you had a perfect energy storage system.

In that time, innovations within the offshore wind industry has led to more powerful machines being developed, meaning NNG will use far fewer turbines than originally envisaged.

Concerns have also been raised that the additional power generated by the massive turbines could supply almost the entire capacity of a proposed new interconnector cable that would transport power to the mainland, meaning no more community schemes could link up to it.

By comparison, removing the aerodynamic interference between propeller - style wind turbines would require spacing them about 20 diameters apart, which means a distance of more than one mile between the largest wind turbines now in use.

Then you have to discharge conditions and order the long lead items, such as grid equipment and turbines — that can mean several more years before you build.

It is possible to build wind turbines without rare earth elements, but doing so increases the complexity, decreases reliability, and jacks the generator weight up, which in turn means all the support structures have to be more massive, all of which results in higher cost.

Which should mean that we can generate more energy from fewer turbines.

In other parts of the world, turbines are going up that are over meters tall, meaning steadier wind speeds and more energy generated.

This does not have to mean more dams, but more turbines at existing dams and a big expansion of capacity to use surplus wind or nuclear to pump water up to a higher dam reservoir.

That means when their turbine is generating more power than they are using, the electric meter spins backward.

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.
